Otherwise, I'm fine with this.

sys/arm/arm/cpuinfo.c
248	Please, follow logic used in this function and use one variable for 'mask' and other for 'set'.
sys/arm/include/cpuinfo.h
129	Only minor nit - plat_cpuinfo doesn't looks like best name - what about: struct cpuinfo_quirks { uint32_t actlr_mask; uint32_t actlr_set; };
