2020-08-26global: Move from bi_memstart/memsize -> gd->ram_base/ram_sizeStefan Roese1-1/+1
With the planned removal of bi_memstart & bi_memsize, this patch now moves the references to the better suiting gd->ram_base/ram_size variables. Signed-off-by: Stefan Roese <sr@denx.de> Reviewed-by: Simon Glass <sjg@chromium.org>
2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada2-2/+2
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit. The semantic patch that makes this change is as follows: <smpl> @@ typedef bd_t; @@ -bd_t +struct bd_info </smpl> Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2020-05-18command: Remove the cmd_tbl_t typedefSimon Glass2-8/+13
We should not use typedefs in U-Boot. They cannot be used as forward declarations which means that header files must include the full header to access them. Drop the typedef and rename the struct to remove the _s suffix which is now not useful. This requires quite a few header-file additions. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-05-18common: Drop net.h from common headerSimon Glass1-0/+1
Move this header out of the common header. Network support is used in quite a few places but it still does not warrant blanket inclusion. Note that this net.h header itself has quite a lot in it. It could be split into the driver-mode support, functions, structures, checksumming, etc. Signed-off-by: Simon Glass <sjg@chromium.org>
2020-02-28watchdog: mpc8xx: Revert the 8xx watchdog back to CONFIG_HW_WATCHDOGChristophe Leroy1-4/+0
Commit f3729ba6e7b2 ("watchdog: mpc8xx_wdt: Watchdog driver and macros cleanup") switched the watchdog to CONFIG_WATCHDOG. But this is not compatible with the 8xx because it starts the watchdog HW timer at reset and must be serviced from the very beginning including while U-boot is executed in the firmware before relocation in RAM. Select CONFIG_HW_WATCHDOG and make hw_watchdog_reset() visible. Meanwhile, finalise the cleanup of arch/powerpc/cpu/mpc8xx/Kconfig by removing the lines put in comment in that commit, and also remove again the selection of CONFIG_MPC8xx_WATCHDOG which was removed by that commit and brought back by mistake by commit b3134ffbd944 ("watchdog: Kconfig: Sort entry alphabetically") Note that there was an 'imply WATCHDOG' in the original commit but it disappeared in the Kconfig alphabetical sorting, so no need to remove it here.

2020-01-17common: Move relocate_code() to init.hSimon Glass1-1/+1
This is an init function so move it out of the common header. Avoid using the typedef so that we don't have to include the global_data header file. Also tidy up the function style in comments while we are here. Signed-off-by: Simon Glass <sjg@chromium.org>
2019-12-02common: Move interrupt functions into a new headerSimon Glass1-0/+1
These functions do not use driver model but are fairly widely used in U-Boot. But it is not clear that they will use driver model anytime soon, so we don't want to label them as 'legacy'. Move them to a new irq_func.h header file. Avoid the name 'irq.h' since it is widely used in U-Boot already. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

With the generic watchdog driver now implemented, this patch removes some legacy stuff from the MPC8xx watchdog driver and its Kconfig integration. CONFIG_MPC8xx_WATCHDOG is completely removed and hw_watchdog_reset() is made static, as the watchdog will now get serviced via the DM infrastructure if enabled via CONFIG_WATCHDOG.

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini11-24/+11
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>

2017-07-22powerpc: Remove unneccessary #ifdefs in reginfoChristophe Leroy1-1/+2
reginfo command is calling mpc8xx_reginfo(), mpc85xx_reginfo() or mpc86xx_reginfo() based on CONFIG_ symbol. As those 3 functions can't me defined at the same time, let's rename them print_reginfo() to avoid the #ifdefs The name is kept generic as it is not at all dependent on powerpc arch and any other arch could want to also print such information. In addition, as the Makefile compiles cmd/reginfo.c only when CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD definition inside a #ifdef CONFIG_CMD_REGINFO Lets all remove the #ifdefs around the U_BOOT_CMD as this file is only compiled when CONFIG_CMD_REGINFO is defined Finally, this is a PowerPC-only command, disable it on a number of non-PowerPC platforms.
