Ok, last night's PXA build regressed with this:
arch/arm/mm/built-in.o: In function `xscale_dma_unmap_area':
cache-xsc3l2.c:(.text+0x4194): undefined reference to `xscale_80200_A0_A1_flush_kern_cache_louis'
That's because we missed that proc-xscale.S aliases a bunch of functions to
xscale_80200_A0_A1_xxx from xscale_xxx. And looking at that, it seems that
we also .type equivalent symbols - have you tested this on T2 builds to
check whether it works correctly there?
