ARC: Implement a function to sync and cleanup caches

2018-03-21T14:06:54Z

Implement specialized function to clenup caches (and therefore sync instruction and data caches) which can be used for cleanup before linux launch or to sync caches during U-Boot self-relocation. Signed-off-by: Eugeniy Paltsev Signed-off-by: Alexey Brodkin

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.

arc: bootm: Move slave cores kick-starting under !fake

2017-11-24T16:38:07Z

Currently slave cores will be kick-started even if we want to dry run bootm which is not what we really want. Signed-off-by: Alexey Brodkin Cc: Eugeniy Paltsev

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

libfdt: replace ARCH_FIXUP_FDT with ARCH_FIXUP_FDT_MEMORY

2016-12-03T03:54:34Z

Commit e2f88dfd2d96 ("libfdt: Introduce new ARCH_FIXUP_FDT option") allows us to skip memory setup of DTB, but a problem for ARM is that spin_table_update_dt() and psci_update_dt() are skipped as well if CONFIG_ARCH_FIXUP_FDT is disabled. This commit allows us to skip only fdt_fixup_memory_banks() instead of the whole of arch_fixup_fdt(). It will be useful when we want to use a memory node from a kernel DTB as is, but need some fixups for Spin-Table/PSCI.

arc: implement slave cores kick-start for Linux kernel

2015-07-01T14:17:27Z

With new SMP-enabled CPUs with ARC HS38 cores and corresponding support in Linux kernel it's required to add basic SMP support in U-Boot. Currently we assume the one and only core starts execution after power-on. So most of things in U-Boot is handled in UP mode. But when U-Boot is used for loading and starting Linux kernel right before jumping to kernel's entry point U-Boot: [1] Sets all slave cores to jump to the same address [kernel's entry point] [2] Really starts all slav cores In ARC's implemetation of SMP in Linux kernel all cores are supposed to run the same start-up code. But only core with ID 0 (master core) processes further while others are looping waiting for master core to complete some initialization. That means it's safe to un-pause slave cores and let them execute kernel - they will wait for master anyway. Signed-off-by: Alexey Brodkin Cc: Vineet Gupta
