Patch name: patch.stray-APP_END
Author: Bryce Denney (bryce@tlw.com)

Detailed description:
In defines.h APP_END is redefined to the wrong value (1024).  With
APP_END=1024, chip erase only clears addresses 0-0x3ff.  0x400 and beyond are
not cleared, so they cannot be reprogrammed correctly.

Removing the #define fixes the problem, and chip erase works correctly again.
