-When invoking an LE kernel from a BE boot loader or vice versa
-the ATAG_CMDLINE command line will be byte swapped, other ATAGs
-are fine because they are 32 bit values.
-
-This patch adds support for a command line option "swx " - which
-must be at the start of the command line - and which is used to
-detect a need to byte swap the rest of the command line.
