Re: [PATCH] ppc32: Fix SCC Uart write problem after 2. open()

["Heiko Schocher" <hs@denx.de>]

Hello,

Sorry, here comes the resubmit of the Patch because
corruption of whitespaces.

on a MPC8260 based Board, i succesfully wrote chars
over a SCC in UART Mode, but after i closed the port
and opened it again, the write() call failed!
(cpm_uart_tx_empty()returns continually 0).
The following Patch will fix this problem.

thanks
Heiko Schocher
