2019-12-02common: Move enable/disable_interrupts out of common.hSimon Glass
Move these two functions into the irq_funcs.h header file. Also move interrupt_handler_t as this is used by the irq_install_handler() function. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>
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>

2019-12-02common: Move some cache and MMU functions out of common.hSimon Glass
These functions belong in cpu_func.h. Another option would be cache.h but that code uses driver model and we have not moved these cache functions to use driver model. Since they are CPU-related it seems reasonable to put them here. Move them over. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Tom Rini <trini@konsulko.com>

2019-05-18CONFIG_SYS_[DI]CACHE_OFF: convert to KconfigTrevor Woerner
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 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>
2019-04-12dts: switch spi-flash to jedec, spi-nor compatibleNeil Armstrong
There is no reason not to use the Linux "jedec,spi-nor" binding in U-Boot dts files. This compatible has been added in sf_probe, let use it. This patch switches to jedec,spi-nor when spi-flash is used in the DTS and DTSI files, and removed spi-flash when jedec,spi-nor is already present. The x86 dts are switched in a separate commit since it depends on a change in fdtdec.

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>

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.
