P30 flash is supported in that it supports CFI.  You can read and write 
to it as long as it's unlocked.  CFI does not support automatic 
unlocking, it assumes if it's locked, it's locked for a reason.  The 
bootloader has to ensure that the sectors occupied by the rootfs are 
unlocked before mounting the filesystem.  We're using P30 here without 
problems.
