2019-05-18CONFIG_SPL_SYS_[DI]CACHE_OFF: addTrevor Woerner2-3/+18
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_[DI]CACHE_OFF: convert to KconfigTrevor Woerner1-0/+12
CONFIG_SYS_[DI]CACHE_OFF had been partially converted to Kconfig parameters; only for the ARC architecture. This patch turns these two parameters into Kconfig items everywhere else they are found. All of the include/configs/* and defconfig changes in this patch are for arm machines only. The Kconfig changes for arc, nds32, riscv, and xtensa have been included since these symbols are found in code under arch/{arc,nds32,riscv,xtensa}, however, no currently-defined include/configs/* or defconfigs for these architectures exist which include these symbols. These results have been confirmed with tools/moveconfig.py.

2019-05-18CONFIG_SYS_[ID]CACHE_OFF: unify the 'any' caseTrevor Woerner1-2/+1
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>

2018-09-10arch: types.h: factor out fixed width typedefs to int-ll64.hMasahiro Yamada1-31/+2
All architectures have the same definition for s8/16/32/64 and u8/16/32/64. Factor out the duplicated code into <asm-generic/int-ll64.h>. BTW, Linux unified the kernel space definition into int-ll64.h a few years ago as you see in Linux commit 0c79a8e29b5f ("asm/types.h: Remove include/asm-generic/int-l64.h").

2018-08-16CONFIG_SYS_GENERIC_BOARD: Finish migrationTom Rini1-18/+0
While we have long since migrated to CONFIG_SYS_GENERIC_BOARD being enabled, we had just a few places left that still referenced or defined it. Update. Signed-off-by: Tom Rini <trini@konsulko.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini44-93/+44
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>

2017-10-02xtensa: Use asm-generic/io.hPaul Burton1-23/+2
Convert the xtensa architecture to make use of the new asm-generic/io.h to provide address mapping functions. As the generic implementations are suitable for xtensa this is primarily a matter of moving code. This has only been build-tested, feedback from architecture maintainers is welcome.

2017-08-16env: Rename getenv/_f() to env_get()Simon Glass1-1/+1
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.

2017-04-13board_f: Rename initdram() to dram_init()Simon Glass1-0/+5

2017-04-05board_f: Make relocation functions genericSimon Glass2-15/+1
This header file is used by three archs. It could be used by all of them since relocation is a common function. Move it into a generic file. Signed-off-by: Simon Glass <sjg@chromium.org>
2016-09-23Remove arch/${ARCH}/include/asm/errno.hMasahiro Yamada1-1/+0
Unlike Linux, nothing about errno.h is arch-specific in U-Boot. As you see, all of arch/${ARCH}/include/asm/errno.h is just a wrapper of <asm-generic/errno.h>. Actually, U-Boot does not export headers to user-space, so we just have to care about the consistency in the U-Boot tree. Now all of include directives for <asm/errno.h> are gone. Deprecate <asm/errno.h>. Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Alexey Brodkin <abrodkin@synopsys.com>
