command, log: print with "log show" a full logbuffer
If the logbuffer contains LOGBUFF_LEN chars, they never got printed with the "log show" command, because chars get printed with the following for loop: for (i = 0; i < (size & LOGBUFF_MASK); i++) { with size = LOGBUFF_LEN and LOGBUFF_MASK = (LOGBUFF_LEN-1) for loop never executed ... Fix this. Signed-off-by: Heiko Schocher <hs@denx.de> Acked-by: Detlev Zundel <dzu@denx.de> Fixed merge conflict. Signed-off-by: Wolfgang Denk <wd@denx.de>
