missing interrupt handling logic for UART4-7 (2014-1-6).
* nuttx/tools/mkconfig.c: Cast size to unsigned in calculation of
CONFIG_RAM_END to avoid complains about integer overflow (2013-1-6).
* nuttx/tools/mkconfig.c: Back out the last change, this causes
problems for assembly language. How to prevent the integer over-
flow warnings? (2014-1-6).
* arch/arm/src/a1x/a1x_serial.c: Handle BUSY interrupt (2014-1-6).
