The demux code for the IRQ EINTs above 3 was

[ARM] 3870/1: AT91: Start removing static memory mappings
This patch removes the static memory mapping for the currently-unused
peripherals [Synchronous Serial, Timer/Counter unit], and for those
drivers that already ioremap() their registers [UART].
Also, the Ethernet driver now uses the platform_device resources but
doesn't yet use ioremap() so we need to pass it the virtual address
instead of the physical address.

On stepping A0/A1 of the 80200, invalidating D-cache by line doesn't
clear the dirty bits, which means that if we invalidate a dirty line,
the dirty data can still be written back to memory later on.
To work around this, dma_inv_range() on these two processors is
implemented as dma_flush_range() (i.e. do a clean D-cache line before
doing the invalidate D-cache line.) For this, we currently have a
