2018-09-10arch: types.h: factor out fixed width typedefs to int-ll64.hMasahiro Yamada
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").

2018-08-08mips: au1x00: Remove support for these SoCsTom Rini
The only platform left for the AU1x00 SoCs was the pb1x00 platform, an apparent clone of the dbau1x00 platform. As pb1x00 had no listed maintainer I am assuming that it is also orphaned. Remove this platform and then remove the unused SoC support.

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>

2018-02-18fdt: Implement weak arch_fixup_fdt()Alexey Brodkin
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.

2017-11-28MIPS: Break out of cache loops for unimplemented cachesPaul Burton
If we run on a CPU which doesn't implement a particular cache then we would previously get stuck in an infinite loop, executing a cache op on the first "line" of the missing cache & then incrementing the address by 0. This was being avoided for the L2 caches, but not for the L1s. Fix this by generalising the check for a zero line size & avoiding the cache op loop when this is the case.

2017-11-28MIPS: Clear instruction hazards in flush_cache()Paul Burton
When writing code, for example during relocation, we ensure that the icache has a coherent view of the new instructions with a call to flush_cache(). This handles the bulk of the work to ensure the new instructions will execute as expected, however it does not ensure that the CPU pipeline doesn't already contain instructions taken from a stale view of the affected memory. This could theoretically be a problem for relocation, but in practice typically isn't because we sync caches for enough code after the entry point of the newly written code that by the time the CPU pipeline might possibly fetch any of it we'll have long ago written it back & invalidated any stale icache entries. This is however a problem for shorter regions of code. In preparation for later patches which write shorter segments of code, ensure any instruction hazards are cleared by flush_cache() by introducing & using a new instruction_hazard_barrier() function which makes use of the jr.hb instruction to clear the hazard.

2017-11-28MIPS: Ensure cache ops complete in cache maintenance functionsPaul Burton
A typical use of cache maintenance functions is to force writeback of data which a device is about to read using DMA - for example a descriptor or command structure. Such users of cache maintenance functions require that operations on the cache have completed before they proceed to instruct a device to read memory. This requires that we place a completion barrier (ie. sync instruction) between the cache ops and whatever write informs the device to perform DMA. Whilst strictly speaking this isn't all users of the cache maintenance functions & we could instead place the barriers in the drivers that require them, it would be much more invasive to do so than to just have the barrier be the default by placing it in the cache functions themselves. The cost is low enough that it shouldn't matter to us in any rare cases that we use the cache functions when not performing DMA.
