Nishanth Menon	861ac52a7e	uart: 16550: Fix getc ... tbz check for RDR status is to check for a bit being zero. Unfortunately, we are using a mask rather than the bit position. Further as per http://www.ti.com/lit/ds/symlink/pc16550d.pdf (page 17), LSR register bit 0 is Data ready status (RDR), not bit position 2. Update the same to match the specification.

Varun Wadekar	c13b2e32f1	Driver for 16550 UART interface ... This patch adds driver for the 16550 UART interface. The driver is exposed as a console, which platforms can use to dump their boot/crash logs. Signed-off-by: Varun Wadekar <vwadekar@nvidia.com>	2015-05-29 11:25:20 +05:30
