Is it not better to have the same mtdparts as in the original stock
firmware and in the next linux kernel ?
Then we will just need small specifics distribution patch to customize
the upstream uboot for the specifics boot params:
In Debian, we need the initrd for raid support system bootup.
It is better to have the same partition scheme in next linux kernel and
in uboot, whatever it will be.
And better to be more closer from the original one, to make end-user
upgrade process simpler.
An alternative will be to have parameters, if possible, to put uboot
distribution wide compatible.
May be a bootstrap call (bootscript call from uboot) or another tweak ?
