Subject: [PATCH] ARM: at91: force CPU selection
Date: Mon,  9 Mar 2015 23:59:58 -0700	[thread overview]
Message-ID: <1425970798-14015-1-git-send-email-computersforpeace@gmail.com> (raw)

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.
