2020-05-18common: Drop asm/ptrace.h from common headerSimon Glass
Move this uncommon header out of the common header. Signed-off-by: Simon Glass <sjg@chromium.org>

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 <sjg@chromium.org>
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 <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
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 <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
2019-05-18CONFIG_SPL_SYS_[DI]CACHE_OFF: addTrevor Woerner
While converting CONFIG_SYS_[DI]CACHE_OFF to Kconfig, there are instances where these configuration items are conditional on SPL. This commit adds SPL variants of these configuration items, uses CONFIG_IS_ENABLED(), and updates the configurations as required.

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 <trevor@toganlabs.com>
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>
2018-02-23xtensa: clean up CONFIG_SYS_TEXT_ADDRMax Filippov
Drop CONFIG_SYS_MEMORY_TOP. Rename CONFIG_SYS_TEXT_ADDR to XTENSA_SYS_TEXT_ADDR. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2017-04-13board_f: Rename initdram() to dram_init()Simon Glass
This allows us to use the same DRAM init function on all archs. Add a dummy function for arc, which does not use DRAM init here. Signed-off-by: Simon Glass <sjg@chromium.org> [trini: Dummy function on nios2] Signed-off-by: Tom Rini <trini@konsulko.com>
2016-08-15xtensa: add support for the xtensa processor architecture [2/2]Chris Zankel
The Xtensa processor architecture is a configurable, extensible, and synthesizable 32-bit RISC processor core provided by Tensilica, inc. This is the second part of the basic architecture port, adding the 'arch/xtensa' directory and a readme file.
