CONFIG_SPL_SYS_[DI]CACHE_OFF: add

2019-05-18T12:15:35Z

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.

CONFIG_SYS_[ID]CACHE_OFF: unify the 'any' case

2019-05-18T12:15:34Z

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

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

Remove unnecessary instances of DECLARE_GLOBAL_DATA_PTR

2018-04-27T18:54:48Z

We have a large number of places where while we historically referenced gd in the code we no longer do, as well as cases where the code added that line "just in case" during development and never dropped it. Signed-off-by: Tom Rini

fdt: Implement weak arch_fixup_fdt()

2018-02-18T19:53:38Z

Only ARM and in some configs MIPS really implement arch_fixup_fdt(). Others just use the same boilerplate which is not good by itself, but what's worse if we try to build with disabled CONFIG_CMD_BOOTM and enabled CONFIG_OF_LIBFDT we'll hit an unknown symbol which was apparently implemented in arch/xxx/lib/bootm.c. Now with weak arch_fixup_fdt() right in image-fdt.c where it is used we get both items highlighted above fixed.

env: Rename getenv/_f() to env_get()

2017-08-16T12:30:24Z

We are now using an env_ prefix for environment functions. Rename these two functions for consistency. Also add function comments in common.h. Quite a few places use getenv() in a condition context, provoking a warning from checkpatch. These are fixed up in this patch also. Suggested-by: Wolfgang Denk Signed-off-by: Simon Glass

nds32: Remove include files from common.h

With a few tweaks we can avoid including these files, which are only needed by two C files. Signed-off-by: Simon Glass
