It looks like the constants used here will break compilation. You
could instead use 0x80000000 and 0xf0000000 and add an 'orr \rx, \rx,
#0x7000' after the 'movne' to fix this.

Just wondering if the UART addresses used here are valid ? since they
do not seem to correspond to the ones listed in hardware.h.
