Hi,
This patch adds the position specific flash_header_0xXXXX section defines
(and friends) so the one barebox image can support multiple boot sources,
for example Nor and SD.
If a board only uses one boot source, the existing generic section defines
are simpler to use, so I've left them.
Cheers
Marc

This (re)enables boards to have multiple boot headers so that the one
image can be used for booting from multiple boot sources.
