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
