| |
earlyprintk messages are not appearing on the terminal emulator during a big endian kernel boot. In BE mode sending full words to UART will result in unprintable characters as they are byte swapped versions of printable ones. So send only bytes.
Signed-off-by: Arun Chandran <achandran@mvista.com> --- --- Changes since v1: removed the byte swapping logic. Just send characters instead. --- arch/arm/include/debug/zynq.S | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
