Hi.
- We should check error bits in psc->sr_csr (not in psc->isr_imr)
- SR_ERROR should also contains SR_RB bit
P.S. Changes were made according with linux code
(http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/drivers/tty/serial/mpc52xx_uart.c
function mpc52xx_uart_int_rx_chars()) and MPC5200b user's manual (chapter
15.2.2.3))
there are some other problems in this area. We have
/* Used to handle more than one channel */
struct per_channel_info channel_info[NUM_PORTS];
but the structure is defined in the source file. So nobody except a debugger
can read these values properly even though this is a global variable.
Maybe we should remove this stuff completely?
