#+--------------------------------------------------------------------------+
#| Relocation address. Set this to the linear address where you want your code
#| to start. It should abide to the following constraints:
#| RELOCADDR >= 0x10200
#| RELOCADDR + 'image file size' < 0xA0000
#| RELOCADDR % 4 = 0 (i.e. aligned on a 4 byte boundary)

# is currently required. It is expected that as of gcc 2.8, the end user
# will be able to override parts of the compilers specs and link using gcc.
