    Subject[PATCH] ARM: at91: force CPU selection
    Date
    The mach-at91 build does not force the user to make a CPU selection.
    This can yield a build failure when SOC_SAM_V7 is used, but neither
    SOC_SAMA5D4 nor SOC_SAMA5D3 are defined:

    arch/arm/include/asm/glue-pf.h:54:2: error: #error Unknown prefetch abort handler type
    #error Unknown prefetch abort handler type
    ^
    make[2]: *** [arch/arm/kernel/asm-offsets.s] Error 1

    The forced default selection is completely arbitrary.
