2024-10-11Merge patch series "Tidy up use of 'SPL' and CONFIG_SPL_BUILD"Tom Rini
Simon Glass <sjg@chromium.org> says: When the SPL build-phase was first created it was designed to solve a particular problem (the need to init SDRAM so that U-Boot proper could be loaded). It has since expanded to become an important part of U-Boot, with three phases now present: TPL, VPL and SPL Due to this history, the term 'SPL' is used to mean both a particular phase (the one before U-Boot proper) and all the non-proper phases. This has become confusing. For a similar reason CONFIG_SPL_BUILD is set to 'y' for all 'SPL' phases, not just SPL. So code which can only be compiled for actual SPL, for example, must use something like this: #if defined(CONFIG_SPL_BUILD) && !defined(CONFIG_TPL_BUILD) In Makefiles we have similar issues. SPL_ has been used as a variable which expands to either SPL_ or nothing, to chose between options like CONFIG_BLK and CONFIG_SPL_BLK. When TPL appeared, a new SPL_TPL variable was created which expanded to 'SPL_', 'TPL_' or nothing. Later it was updated to support 'VPL_' as well. This series starts a change in terminology and usage to resolve the above issues: - The word 'xPL' is used instead of 'SPL' to mean a non-proper build - A new CONFIG_XPL_BUILD define indicates that the current build is an 'xPL' build - The existing CONFIG_SPL_BUILD is changed to mean SPL; it is not now defined for TPL and VPL phases - The existing SPL_ Makefile variable is renamed to SPL_ - The existing SPL_TPL Makefile variable is renamed to PHASE_ It should be noted that xpl_phase() can generally be used instead of the above CONFIGs without a code-space or run-time penalty. This series does not attempt to convert all of U-Boot to use this new terminology but it makes a start. In particular, renaming spl.h and common/spl seems like a bridge too far at this point. The series is fully bisectable. It has also been checked to ensure there are no code-size changes on any commit.

2024-09-24at91: rename mem_init() to at91_mem_init()Jerome Forissier
The AT91-based platforms have a mem_init() function declared in arch/arm/mach-at91/include/mach/at91_common.h and implemented in various places. In preparation of the introduction of the lwIP networking library which also has a global mem_init() function, rename the AT91 one to at91_mem_init().

2021-02-02common: Drop asm/global_data.h from common headerSimon Glass
Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
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>
2020-05-18common: Drop net.h from common headerSimon Glass
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>

2019-12-02Move strtomhz() to vsprintf.hSimon Glass

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
