Have checked with the designer of the UART block and he confirmed that
the 2835 PL011 contains a 16 deep fifo not 32 deep...
Hardware guys, they can never just leave it alone!!!

Stephen Warren reported the recent commit 78506f2 (add support for
extended FIFO-size of PL011-r1p5) breaks the serial port on the
BCM2835 ARM SoC.
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 li
