2025-11-28xtensa: Assure end of U-Boot is at 8-byte aligned offsetMarek Vasut
Make sure the end of U-Boot is at 8-byte aligned offset, not 4-byte aligned offset. This allows safely appending DT at the end of U-Boot with the guarantee that the DT will be at 8-byte aligned offset. This 8-byte alignment is now checked by newer libfdt 1.7.2 .

2024-07-04xtensa: Correct define of _end symbolJiaxun Yang
So U-Boot is using _end symbol to detect location of devicetree appended at the end of the ROM. It needs to be calculated based on end of .data load address, as in our lds .current address is address in RAM. Tested-by: Max Filippov <[email protected]> Signed-off-by: Jiaxun Yang <[email protected]>

2024-05-06xtensa: Remove <common.h> and add needed includesTom Rini
Remove <common.h> from all xtensa architecture files and when needed add missing include files directly. Signed-off-by: Tom Rini <[email protected]>
2022-12-05global: Move remaining CONFIG_SYS_SDRAM_* to CFG_SYS_SDRAM_*Tom Rini
The rest of the unmigrated CONFIG symbols in the CONFIG_SYS_SDRAM namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace. Signed-off-by: Tom Rini <[email protected]> Reviewed-by: Simon Glass <[email protected]>
2022-06-23linker_lists: Rename sections to remove . prefixAndrew Scull
Rename the sections used to implement linker lists so they begin with '__u_boot_list' rather than '.u_boot_list'. The double underscore at the start is still distinct from the single underscore used by the symbol names. Having a '.' in the section names conflicts with clang's ASAN instrumentation which tries to add redzones between the linker list elements, causing expected accesses to fail. However, clang doesn't try to add redzones to user sections, which are names with all alphanumeric and underscore characters.

2021-05-24treewide: Convert macro and uses of __section(foo) to __section("foo")Marek BehĂșn
This commit does the same thing as Linux commit 33def8498fdd. Use a more generic form for __section that requires quotes to avoid complications with clang and gcc differences. Remove the quote operator # from compiler_attributes.h __section macro. Convert all unquoted __section(foo) uses to quoted __section("foo"). Also convert __attribute__((section("foo"))) uses to __section("foo") even if the __attribute__ has multiple list entry forms.

2020-01-17common: Move relocate_code() to init.hSimon Glass
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 <[email protected]>
2019-12-02common: Move interrupt functions into a new headerSimon Glass
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 <[email protected]> Reviewed-by: Tom Rini <[email protected]>
2019-12-02Move strtomhz() to vsprintf.hSimon Glass
At present this function sits in its own file but it does not really justify it. There are similar string functions in vsprintf.h, so move it there. Also add the missing function comment. Use the vsprintf.h include file explicitly where needed. Signed-off-by: Simon Glass <[email protected]> Reviewed-by: Tom Rini <[email protected]>

While converting CONFIG_SYS_[DI]CACHE_OFF to Kconfig, there are instances where these configuration items are conditional on SPL.

2019-05-18CONFIG_SYS_[ID]CACHE_OFF: unify the 'any' caseTrevor Woerner
According to De Morgan's Law[1]: !(A && B) = !A || !B !(A || B) = !A && !B There are 5 places in the code where we find: #if !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF)) and 4 places in the code where we find: #if (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF)) In words, the construct: !defined(CONFIG_SYS_[DI]CACHE_OFF) means: "is the [DI]CACHE on?" and the construct: defined(CONFIG_SYS_[DI]CACHE_OFF) means: "is the [DI]CACHE off?" Therefore !(defined(CONFIG_SYS_ICACHE_OFF) && defined(CONFIG_SYS_DCACHE_OFF)) means: "the opposite of 'are they both off?'" in other words: "are either or both on?" and: (!defined(CONFIG_SYS_ICACHE_OFF) || !defined(CONFIG_SYS_DCACHE_OFF) means: "are either or both on?" As a result, I've converted the 4 instances of '(!A || !B)' to '!(A && B)' for consistency. [1] https://en.wikipedia.org/wiki/De_Morgan%27s_laws Signed-off-by: Trevor Woerner <[email protected]>
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 <[email protected]>
