[PATCH] powerpc: udbg updates
The udbg low level io layer has an issue with udbg_getc() returning a char (unsigned on ppc) instead of an int, thus the -1 if you had no available input device could end up turned into 0xff, filling your display with bogus characters. This fixes it, along with adding a little blob to xmon to do a delay before exiting when getting an EOF and fixing the detection of ADB keyboards in udbg_adb.c Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
