Tom already applied the patch to mainline ...

Thats linux ... not u-boot!

Ok, nice to hear!

> How can the 8xx survive without U-boot support ?

Tom asked (I think a lot of times) regarding converting mpc8xx to
Kconfig / DM and nobody did the necessary steps. We also asked
our customers if they can do the necessary changes, none was interested.

So, if you need mpc8xx support in U-Boot, simply add it again with
Kconfig and DM support included!

bye,
Heiko
