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.

Convert the mips architecture to make use of the new asm-generic/io.h to provide address mapping functions. As mips actually performs non-identity mapping between physical & virtual addresses we can't simply make use of the generic functions, with the exception of being able to drop our no-op unmap_physmem() and definitions of unused map flags.

2017-08-15env: Convert CONFIG_ENV_IS_IN... to a choiceSimon Glass
At present we support multiple environment drivers but there is not way to select between them at run time. Also settings related to the position and size of the environment area are global (i.e. apply to all locations). Until these limitations are removed we cannot really support more than one environment location. Adjust the location to be a choice so that only one can be selected. By default the environment is 'nowhere', meaning that the environment exists only in memory and cannot be saved. Also expand the help for the 'nowhere' option and move it to the top since it is the default.

2017-07-27mips: spl: configure SYS_MALLOC_F_LEN independently for SPL and full U-BootAndy Yan
Some platforms have very limited SRAM to run SPL code, so there may not be the same amount space for a malloc pool before relocation in the SPL stage as the normal U-Boot stage. Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.

2017-07-25Convert CONFIG_ENV_IS_IN_MMC/NAND/UBI and NOWHERE to KconfigSimon Glass
This converts the following to Kconfig: CONFIG_ENV_IS_IN_MMC CONFIG_ENV_IS_IN_NAND CONFIG_ENV_IS_IN_UBI CONFIG_ENV_IS_NOWHERE In fact this already exists for sunxi as a 'choice' config. However not all the choices are available in Kconfig yet so we cannot use that. It would lead to more than one option being set. In addition, one purpose of this series is to allow the environment to be stored in more than one place. So the existing choice is converted to a normal config allowing each option to be set independently. There are not many opportunities for Kconfig updates to reduce the size of this patch. This was tested with ./tools/moveconfig.py -i CONFIG_ENV_IS_IN_MMC And then manual updates. This is because for CHAIN_OF_TRUST boards they can only have ENV_IS_NOWHERE set, so we enforce that via Kconfig logic now.
