Hi
It is a V2 serie after Marek feedback for
http://patchwork.ozlabs.org/project/uboot/list/?series=168378
This serie allows dcache activation in SPL or in U-Boot preloc stage
for ARM board.
See "arm: stm32mp1: activate data cache in SPL and before relocation"
for example of usage in SPL and in U-Boot pre-reloc of the function
dcache_enable() and of mmu_set_region_dcache_behaviour().
A branch named "dcache" with the needed patches for stm32mp1 boards
is available in:
https://gitlab.denx.de/u-boot/custodians/u-boot-stm.git
Changes in v2:
- update patch after Marek's proposal. but I just divided by 2 instead
of 4kB (minimal MMU page size)
Patrick Delaunay (3):
arm: caches: protect dram_bank_mmu_setup access to bi_dram
arm: caches: add DCACHE_DEFAULT_OPTION
arm: caches: manage phys_addr_t overflow in
mmu_set_region_dcache_behaviour
