Minimon is loaded to 0x0ffff000 by uart_boot, so it needs to be linked to that address as well, or it won't work. Also add that hint to the README, fix a warning, and fix the disassembly base address (was wrong either way).

 with the UART boot mod. 
 It allows to read and write memory, flash program, execute code.
 This is suitable to reflash the box, load Rockbox or the gdb stub, etc.

+The SVN version is linked to 0x0ffff000, i.e. start of IRAM.
+This address has to match the address uart_boot downloads it to.
