A UART compatible with the ARM PL011-r1p5 should have 32-deep FIFOs. The BCM2835 UART just looks like an ARM PL011-r1p5, but has 16-deep FIFOs just like PL011-r1p4 or earlier revisions. As a workaround for this compatibility issue, this patch overrides the HW UART periphid register values with the actually compatible UART periphid 0x00241011 (r1p3 or r1p4).
