With CONFIG_OMAP4_ERRATA_I688 enabled, omap2+ build
was broken as below:
arch/arm/kernel/io.c: In function '_memcpy_toio':
arch/arm/kernel/io.c:29: error: implicit declaration of function 'outer_sync'
make[1]: *** [arch/arm/kernel/io.o] Error 1
This was caused by commit 9f97da78 (Disintegrate asm/system.h for ARM).
