Out of curiosity: what are the problems if the D-Cache is turned on?

I don't remember this was asked when we submitted the original imxrt1050-evk_defconfig

The problem is that mmu_set_region_dcache_behaviour() is not implemented for armv7m and mxsfb.c requires it when DCache is enabled, that's why I've disabled.

So we can keep it as is or implement armv7m complete mmu_set_region_dcache_behaviour()

Best regards
