Two partitions at same place are bad news... Please expand on "bad news"? What are the runtime effects of this change? Decisions about which kernel(s) to patch depend on this info.

Well... two partitions at same place. If you use one, you will corrupt information on the other one. OTOH this moves partition around (so that they don't overlap) so it is probably not stable candidate. I guess this is not huge issue; people using these boards probably have custom dts changes, anyway... Best regards, Pavel

Or no one's even using it anymore. I can take this via powerpc, I won't mark it for stable etc. cheers

Fix it by shifting the second partition. Signed-off-by: Pavel Machek <pavel@ucw.cz> [mpe: Reconstruct change log from email thread] Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> Minor nit, your From: address doesn't match your Signed-off-by: address, which trips my "check patch is signed-off-by author" script. I can just ignore it, but I think it's preferable if they match. cheers

It is still me, but I guess denx should get the credit here, so you can use. Signed-off-by: Pavel Machek <pavel@denx.de> Thanks, Pavel
