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 -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany
