From: Ben Dooks Date: Wed, 25 Mar 2015 11:27:46 +0000 (+0000) Subject: ARM: debug: fix big endian operation for 8250 word mode X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=6ef4e47926b2008c6a1736fe4e3b2817e3b95463;p=linux-beck.git ARM: debug: fix big endian operation for 8250 word mode If the 8250 debug code is used in word mode on an big endian host then the writes need to be change into little endian for the bus. Note, we have to re-convert the value back as the debug code will inspect the value after writing it to see if a newline has been written.
