* env: Move env_get_f() to env.hSimon Glass2019-08-111-0/+1

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-078-17/+8
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
* libfdt: move headers to <linux/libfdt.h> and <linux/libfdt_env.h>Masahiro Yamada2018-03-051-1/+1
| | | | | | | | | | | | | | | | | Thomas reported U-Boot failed to build host tools if libfdt-devel package is installed because tools include libfdt headers from /usr/include/ instead of using internal ones. This commit moves the header code: include/libfdt.h -> include/linux/libfdt.h include/libfdt_env.h -> include/linux/libfdt_env.h and replaces include directives: #include <libfdt.h> -> #include <linux/libfdt.h> #include <libfdt_env.h> -> #include <linux/libfdt_env.h> Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com>
* env: Rename getenv/_f() to env_get()Simon Glass2017-08-161-2/+2
| | | | | | | | | | | We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also.

* fdt: Allow ft_board_setup() to report failureSimon Glass2014-11-211-2/+3
| | | | | | | | | | | | | | | | | | This function can fail if the device tree runs out of space. Rather than silently booting with an incomplete device tree, allow the failure to be detected. Unfortunately this involves changing a lot of places in the code. I have not changed behvaiour to return an error where one is not currently returned, to avoid unexpected breakage. Eventually it would be nice to allow boards to register functions to be called to update the device tree. This would avoid all the many functions to do this. However it's not clear yet if this should be done using driver model or with a linker list. This work is left for later.

| | | | | | | | | | | | | | | | | | | | We have switched to Kconfig and the boards.cfg file is going to be removed. We have to retrieve the board status and maintainers information from it. The MAINTAINERS format as in Linux Kernel would be nice because we can crib the scripts/get_maintainer.pl script. After some discussion, we chose to put a MAINTAINERS file under each board directory, not the top-level one because we want to collect relevant information for a board into a single place.

* kconfig: add board Kconfig and defconfig filesMasahiro Yamada2014-07-301-0/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds: - arch/${ARCH}/Kconfig provide a menu to select target boards - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig set CONFIG macros to the appropriate values for each board - configs/${TARGET_BOARD}_defconfig default setting of each board (This commit was automatically generated by a conversion script based on boards.cfg) In Linux Kernel, defconfig files are located under arch/${ARCH}/configs/ directory. It works in Linux Kernel since ARCH is always given from the command line for cross compile. But in U-Boot, ARCH is not given from the command line. Which means we cannot know ARCH until the board configuration is done. That is why all the "*_defconfig" files should be gathered into a single directory ./configs/.

* 8xxx: Change all 8*xx_DDR addresses to 8xxxAndy Fleming2012-11-271-1/+1
| | | | | | | | | | | | | | | | | | | | | | There were a number of shared files that were using CONFIG_SYS_MPC85xx_DDR_ADDR, or CONFIG_SYS_MPC86xx_DDR_ADDR, and several variants (DDR2, DDR3). A recent patchset added 85xx-specific ones to code which was used by 86xx systems. After reviewing places where these constants were used, and noting that the type definitions of the pointers assigned to point to those addresses were the same, the cleanest approach to fixing this problem was to unify the namespace for the 85xx, 83xx, and 86xx DDR address definitions. This patch does: s/CONFIG_SYS_MPC8.xx_DDR/CONFIG_SYS_MPC8xxx_DDR/g All 85xx, 86xx, and 83xx have been built with this change.

| | | | | | | | | | | | | | Move fsl_ddr_get_spd into common mpc8xxx/ddr/main.c as most boards pretty much do the same thing. The only variations are in how many controllers or DIMMs per controller exist. To make this work we standardize on the names of the SPD_EEPROM_ADDRESS defines based on the use case of the board.

* mpc85xx boards: initdram() cleanup/bugfixBecky Bruce2011-01-141-14/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Correct initdram to use phys_size_t to represent the size of dram; instead of changing this all over the place, and correcting all the other random errors I've noticed, create a common initdram that is used by all non-corenet 85xx parts. Most of the initdram() functions were identical, with 2 common differences: 1) DDR tlbs for the fixed_sdram case were set up in initdram() on some boards, and were part of the tlb_table on others. I have changed them all over to the initdram() method - we shouldn't be accessing dram before this point so they don't need to be done sooner, and this seems cleaner. 2) Parts that require the DDR11 erratum workaround had different implementations - I have adopted the version from the Freescale errata document. It also looks like some of the versions were buggy, and, depending on timing, could have resulted in the DDR controller being disabled. This seems bad. The xpedite boards had a common/fsl_8xxx_ddr.c; with this change only the 517 board uses this so I have moved the ddr code into that board's directory in xpedite517x.c Signed-off-by: Becky Bruce <beckyb@kernel.crashing.org> Tested-by: Paul Gortmaker <paul.gortmaker@windriver.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* Switch from archive libraries to partial linkingSebastien Carlier2010-11-171-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier <sebastien.carlier@gmail.com>

| | | | | | | | | | | | | | | | | | | | | Currently, 83xx, 86xx, and 85xx have a lot of duplicated code dedicated to defining and manipulating the LBC registers. Merge this into a single spot. To do this, we have to decide on a common name for the data structure that holds the lbc registers - it will now be known as fsl_lbc_t, and we adopt a common name for the immap layouts that include the lbc - this was previously known as either im_lbc or lbus; use the former. In addition, create accessors for the BR/OR regs that use in/out_be32 and use those instead of the mismash of access methods currently in play.

* Redundant Environment: protect full sector sizeWolfgang Denk2009-06-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several boards used different ways to specify the size of the protected area when enabling flash write protection for the sectors holding the environment variables: some used CONFIG_ENV_SIZE and CONFIG_ENV_SIZE_REDUND, some used CONFIG_ENV_SECT_SIZE, and some even a mix of both for the "normal" and the "redundant" areas. Normally, this makes no difference at all. However, things are different when you have to deal with boards that can come with different types of flash chips, which may have different sector sizes. Here we may have to chose CONFIG_ENV_SECT_SIZE such that it fits the biggest sector size, which may include several sectors on boards using the smaller sector flash types. In such a case, using CONFIG_ENV_SIZE or CONFIG_ENV_SIZE_REDUND to enable the protection may lead to the case that only the first of these sectors get protected, while the following ones aren't. This is no real problem, but it can be confusing for the user - especially on boards that use CONFIG_ENV_SECT_SIZE to protect the "normal" areas, while using CONFIG_ENV_SIZE_REDUND for the "redundant" area. To avoid such inconsistencies, I changed all sucn boards that I found to consistently use CONFIG_ENV_SECT_SIZE for protection. This should not cause any functional changes to the code.

* Fix all linker script to handle all rodata sectionsTrent Piepho2009-03-201-3/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A recent gcc added a new unaligned rodata section called '.rodata.str1.1', which needs to be added the the linker script. Instead of just adding this one section, we use a wildcard ".rodata*" to get all rodata linker section gcc has now and might add in the future. However, '*(.rodata*)' by itself will result in sub-optimal section ordering. The sections will be sorted by object file, which causes extra padding between the unaligned rodata.str.1.1 of one object file and the aligned rodata of the next object file. This is easy to fix by using the SORT_BY_ALIGNMENT command. This patch has not be tested one most of the boards modified. Some boards have a linker script that looks something like this: *(.text) . = ALIGN(16); *(.rodata) *(.rodata.str1.4) *(.eh_frame) I change this to: *(.text) . = ALIGN(16); *(.eh_frame) *(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*))) This means the start of rodata will no longer be 16 bytes aligned. However, the boundary between text and rodata/eh_frame is still aligned to 16 bytes, which is what I think the real purpose of the ALIGN call is. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org>

Make the bss end address aligned by 4, so that the loop will end as expected. Signed-off-by: Selvamuthukumar <selva.muthukumar@e-coninfotech.com> Signed-off-by: Wolfgang Denk <wd@denx.de>
* Pass dimm parameters to populate populate controller optionsHaiying Wang2008-10-181-1/+4
| | | | | | | | | | | | | Because some dimm parameters like n_ranks needs to be used with the board frequency to choose the board parameters like clk_adjust etc. in the board_specific_paramesters table of the board ddr file, we need to pass the dimm parameters to the board file. * move ddr dimm parameters header file from /cpu to /include directory. * add ddr dimm parameters to populate board specific options. * Fix fsl_ddr_board_options() for all the 8xxx boards which call this function.

* socrates: fix crash after relocationAnatolij Gustschin2008-09-221-1/+1
| | | | | | | | | | Currently U-Boot crashes after relocation to RAM. Changing the CPO value of the DDR SDRAM TIMING_CFG_2 register to READ_LAT + 1 (to the value it was before conversion of socrates to new DDR code) fixes the problem. Signed-off-by: Anatolij Gustschin <agust@denx.de>
* 85xx: socrates: autoprobe Lime chipu-boot@bugs.denx.de2008-09-131-15/+43
| | | | | | | | | This patch is an attempt to implement autoprobing for the Lime presence on the bus. Configure GPCM for Lime CS2 and try to access chip ID registers. Second read atempt delivers register values if the chip is present. Signed-off-by: Anatolij Gustschin <agust@denx.de>

* 85xx: socrates: Enable Lime support.Anatolij Gustschin2008-09-094-2/+233
| | | | | | | | | This patch adds Lime GDC support together with support for the PWM backlight control through the w83782d chip. The reset pin of the latter is attached to GPIO, so we need to reset it in early_board_init_r. Signed-off-by: Anatolij Gustschin <agust@denx.de>
* 85xx: Socrates: Major code update.Detlev Zundel2008-09-092-49/+65
| | | | | | | | | | | | | | | | | - Update the local bus ranges in the FDT for Linux for the various devices connected to the local bus via chip-select. - Set the LCRR_DBYP bit in the LCRR for local bus frequencies lower than 66 MHz and uses I/O accessor functions consequently. - UPM data update. - Update of default environment and configuration. Use I2C multibus as we do have two I2C buses. Also enable sdram and ext2 commands.
