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 arch/arm/include/asm/system.h | 8 ++++++++ arch/arm/lib/cache-cp15.c | 20 ++++++++++---------- 2 files changed, 18 insertions(+), 10 deletions(-)
