audioniek, but you are right(shame on you, Fortis!),
in fact by factory default the bootargs sector ( 0xa0040000-0xa005ffff ) is empty and the loaders only use the embedded bootargs. whenever a "saveenv" is done at the serial console the bootargs are saved to the flash and then are preferred if the sector info is correct.
and to all:
the git MTD info and MTD partition layout is NOT the same as uboot/iboot mtds. its a thing for the coder to use the proper values and take care things go right.
