>From 0 to 0x10000 is reserved for the ROM monitor. You can reclaim it if
you like, but then you won't be able to use the ROM monitor services for
e.g. debugging. To do that you configure your application with
CYGSEM_HAL_USE_ROM_MONITOR disabled, and then adjust your memory map to use
the memory from 0x0 (similar to how the ROM startup does).
