Hello Tom,
By bisectable, i mean that early patches do not depend on later patches. It should be possible to just apply patch 1 without applying any of the other patch.
Patch 1 looks like is contains the union of all the config file changes. What it should have contained was only 1 change adding CONFIG_AT91_LEGACY. Fixing this will mean separating this changes into their logical parts and rebasing the patchset to include then in the correct order. This is a task best done as you develop instead of after the fact. This is why i recommended that it may be easier to break this patchset into multiple pieces and submit them separately.
I have fully restructured the patch. I will send this as V3 within the next hour. The Parts are now only depended from 9 to 1, but independed from 1 to 9.
regards
Jens
