* arch: Move NEEDS_MANUAL_RELOC symbol to KconfigMichal Simek2020-11-041-4/+0

* microblaze: Switch to generic bootm implementationMichal Simek2019-10-081-0/+2
| | | | | | | | | | | | | | There is no reason to use private code for standard bootm command. Current implementation is also broken and don't support image relocation properly. Switching to generic bootm implementation is fixing these issues. cmdline and bdt bootm subcommands are returning -1 because they are not implemented. Similar change was done long time ago by for example commit 2bb5b638791d ("MIPS: bootm: rework and fix broken bootm code") Signed-off-by: Michal Simek <michal.simek@xilinx.com>

BTW, Linux unified the kernel space definition into int-ll64.h a few years ago as you see in Linux commit 0c79a8e29b5f ("asm/types.h: Remove include/asm-generic/int-l64.h").

* microblaze: Convert generic platform to DM gpioMichal Simek2018-07-191-13/+0
| | | | | | | | | | | | | | | | | | | | | | | | Converting GPIO to DM requires to do changes in reset subsystem that's why support for Microblaze soft reset via sysreset and GPIO sysreset support was added. These two patches enables enabling GPIO DM. Microblaze soft reset is bind at last reset method. GPIO reset is handled via sysreset with adding this fragment to DT. gpio-restart { compatible = "gpio-restart"; gpios = <&reset_gpio 0 0 0>; /* 3rd cell ACTIVE_HIGH = 0, ACTIVE_LOW = 1 */ }; hard-reset-gpio property is not documented and also handled. Conversion is required. Unfortunately do_reset is required for SPL that's why use only soft microblaze reset for now. Signed-off-by: Michal Simek <michal.simek@xilinx.com>

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-0710-19/+10
| | | | | | | | | | | | | | | | | | | | 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>

* Remove arch/${ARCH}/include/asm/errno.hMasahiro Yamada2016-09-231-1/+0
| | | | | | | | | | | | | | Unlike Linux, nothing about errno.h is arch-specific in U-Boot. As you see, all of arch/${ARCH}/include/asm/errno.h is just a wrapper of <asm-generic/errno.h>. Actually, U-Boot does not export headers to user-space, so we just have to care about the consistency in the U-Boot tree. Now all of include directives for <asm/errno.h> are gone.

* microblaze: Fix C99/gnu99 compatiblity for inline functionsNathan Rossi2015-11-192-43/+22
| | | | | | | | | | | | | | | | | 'extern inline' is not portable across various C standards. To ensure compatiblity with various standards/compilers change the functions to static inline. This is a portable construct and serves as a comparable definition to 'extern inline' from the gnu90 standard. Additionally remove the function prototypes as they are not required due to the functions being declared static and functions are correctly ordered based on dependence.

| | | | | | | | | | | | | | | | | | | | | | | | Microblaze uses gpio which is connected to the system reset. Currently gpio subsystem wasn't used for it.

* Introduce generic link section.h symbol filesSimon Glass2013-03-151-0/+27
| | | | | | | | | | | | | | | | | | We create a separate header file for link symbols defined by the link scripts. It is helpful to have these all in one place and try to make them common across architectures. Since Linux already has a similar file, we bring this in even though many of the symbols there are not relevant to us. Each architecture has its own asm/sections.h where symbols specifc to that architecture can be added. For now everything except AVR32 just includes the generic header. One change is needed in arch/avr32/lib/board.c to make this conversion work. Reviewed-by: Tom Rini <trini@ti.com> (version 5) Signed-off-by: Simon Glass <sjg@chromium.org>
