* Clean up libfdt.h includesGerald Van Baren2013-02-081-1/+0
| | | | | | | | | | The libfdt.h file is the definition file for libfdt. It is unnecessary to include other fdt header files (the necessary ones are pulled in by libfdt.h). Signed-off-by: Gerald Van Baren <gvb@unssw.com> Acked-by: Simon Glass <sjg@chromium.org> Acked-by: Stefan Roese <sr@denx.de>

* usb: use linux/usb/ch9.h instead of usbdescriptors.hIlya Yanok2012-11-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | Linux usb/ch9.h seems to have all the same information (and more) as usbdescriptors.h so use the former instead of the later one. As a consequense of this change USB_SPEED_* values don't correspond directly to EHCI speed encoding anymore, I've added necessary recoding in EHCI driver. Also there is no point to put speed into pipe anymore so it's removed and a bunch of host drivers fixed to look at usb_device->speed instead. Old usbdescriptors.h included is not removed as it seems to be used by old USB device code. This makes usb.h and usbdevice.h incompatible. Fortunately the only place that tries to include both are the old MUSB code and it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute on musb_regs structure but this attribute seems to be unneeded (old MUSB code doesn't support any DMA at all).

* common: Discard the __u_boot_cmd sectionMarek Vasut2012-10-221-3/+0
| | | | | | | | | | | The command declaration now uses the new LG-array method to generate list of commands. Thus the __u_boot_cmd section is now superseded and redundant and therefore can be removed. Also, remove externed symbols associated with this section from include/command.h .

* serial: powerpc: Implement CONFIG_SERIAL_MULTI into iop480 serial driverMarek Vasut2012-10-151-6/+59
| | | | | | | | | | | | | | Implement support for CONFIG_SERIAL_MULTI into iop480 serial driver. This driver was so far only usable directly, but this patch also adds support for the multi method. This allows using more than one serial driver alongside the iop480 driver. Also, add a weak implementation of default_serial_console() returning this driver.

* PPC405EX CHIP_21 erratumSteven A. Falco2011-05-121-0/+64
| | | | | | | | | | | | | | | | | | | | | | | | | | | APM errata CHIP_21 for the 405EX/EXr (from the rev 1.09 document dated 4/27/11) states that rev D processors may wake up with the wrong feature set. This patch implements the APM-proposed workaround. To enable this patch for your board, add the appropriate define for your CPU to your board header file. See kilauea.h for more information. The following variants are supported: #define CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EXr_NO_SECURITY #define CONFIG_SYS_4xx_CHIP_21_405EXr_SECURITY Please note that if you select the wrong define, your board will not boot, and JTAG will be required to recover. Tested on custom boards using: CONFIG_SYS_4xx_CHIP_21_405EX_NO_SECURITY <sfalco@harris.com> CONFIG_SYS_4xx_CHIP_21_405EX_SECURITY <eibach@gdsys.de> Signed-off-by: Steve Falco <sfalco@harris.com> Acked-by: Dirk Eibach <eibach@gdsys.de> Signed-off-by: Stefan Roese <sr@denx.de>
* Revert "PowerPC: Add support for -msingle-pic-base"Wolfgang Denk2011-04-201-20/+2
| | | | | | | This reverts commit 39768f7715ed637ef02f49fc7de664cc1aaf14b3. Reson: it breaks a number of boards with embedded environment as the code size grows in some places.
* PowerPC: Add support for -msingle-pic-baseJoakim Tjernlund2011-04-111-2/+20
| | | | | | | | | | | | | -msingle-pic-base is a new gcc option for ppc and it reduces the size of my u-boot with 6-8 KB. While at it, add -fno-jump-tables too to save a few more bytes. -msingle-pic-base will be in gcc 4.6, however backported patches are available at http://bugs.gentoo.org/show_bug.cgi?id=347281 Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
* PowerPC: Move -fPIC flag to common placeJoakim Tjernlund2011-04-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | The -fPIC flag belongs with -mrelocatable, move it there. Also change -fPIC to -fpic as this produces smaller binaries. However, currently -mrelocatable promotes -fpic to -fPIC, a fix for this is in upcoming gcc 4.6 or you can apply this small patch to gcc: diff --git a/gcc/config/rs6000/sysv4.h b/gcc/config/rs6000/sysv4.h index 8da8410..e4b8280 100644 --- a/gcc/config/rs6000/sysv4.h +++ b/gcc/config/rs6000/sysv4.h @@ -227,7 +227,8 @@ do { \ } \ \ else if (TARGET_RELOCATABLE) \ - flag_pic = 2; \ + if (!flag_pic) \ + flag_pic = 2; \ } while (0) #ifndef RS6000_BI_ARCH -- Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>

* ppc4xx: Flush complete dcache in relocate_code()Stefan Roese2010-11-281-6/+7
| | | | | | | | | When the cache is enabled in SDRAM we need to flush not only the global data area but also the bd_info struct in relocate_code. This patch now flushed the complete dcache (all dcache lines) via flush_dcache() instead of adding a flush_dcache_range() call for bd_info since this is faster.

* arch/powerpc/*/config.mk: make CONFIG_SYS_LDSCRIPT settings workWolfgang Denk2010-11-261-4/+1
| | | | | | | | | | | | | | | | | | | | | | | | | As we try to get rid of board specific config.mk files we must provide a way for board specific settings of the LDSCRIPT variable (path to the linker script) where needed. We now implement the following hierarchy: - Highest priority has a "#define CONFIG_SYS_LDCONFIG" in the board config file. - If CONFIG_SYS_LDCONFIG is not set, and the system is booting from NAND (CONFIG_NAND_SPL is set), then a board specific linker script board/$(BOARDDIR)/u-boot-nand.lds gets used. - If we are not booting from NAND, we test if a processor specific linker script arch/powerpc/cpu/$(CPU)/u-boot.lds exists; if so we use that. - As default, arch/powerpc/config.mk gets used.

* 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>
* PowerPC: Don't destroy fixup table while doing fixupsJoakim Tjernlund2010-11-141-1/+1
| | | | | | | | | The fixup procedure just stored a constant value in the fixup table rather than just adjusting the table. Although that doesn't seem to do any harm, it prevents relocation more that once. Signed-off-by: Joakim Tjernlund <Joakim.Tjernlund@transmode.se>
