[U-Boot-Users] [PATCH 1/2] add MPC8343 based board mvBlueLYNX-M7 aka mvblm7

["André Schwarz" <Andre.Schwarz@matrix-vision.de>]

Kim,

please review this resubmitted patch with changes as you have requested :

- coding style issues
- Makefile
- Maintainer
- common mpc83xx PCI code
- added README.mvblm7

Please let me know if anything is still invalid or not acceptable.

As mentioned before the merge window is close -> take it into "next" please.

Due to size I have to split the patch.

Thanks,
Andre
