Why rboot need up to addr 0x2000? #34

Hello Raburton,

Why have you specify that rboot is placed between addr 0x00000 and 0x2000? Ok for addr 0x0000 but the bootloader and the structure fo rboot config don't really need of all that?

rBoot needs about half a sector. The config needs very little space, but needs to be in a separate sector so when it is rewritten there is no risk of losing the bootloader itself.
