Re: MPC5200b MMC over SPI into PSC6

Hello!
I've seen you guys are playing with a Lite5200b board, so I've decided
to do another attempt with mine.

If I'm not wrong, the right sequence of commands should be the following:

$ make ARCH=powerpc mpc5200_defconfig
$ make ARCH=powerpc menuconfig
... [customizations]...
$ make ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- cuImage.lite5200b

and this is the output:
...
  CHK     include/linux/version.h
  CHK     include/linux/utsrelease.h
  CALL    scripts/checksyscalls.sh
  CHK     include/linux/compile.h
  CALL    arch/powerpc/kernel/systbl_chk.sh
  WRAP    arch/powerpc/boot/cuImage.lite5200b

At this point I've loaded the cuImage and rootfs.uimage on the board:
=> usb start
=> usb scan
=> fatload usb 0 0x03000000 cuImage.lite5200b
=> fatload usb 0 0x04000000 rootfs.uimage
=> bootm 0x03000000 0x04000000

but it still hangs after this:

I've looked at Load Address and Entry Point of the cuImage and it
sounds a little strange to me that these values are not zero, so I've
manually changed them both to  0x00000000 using mkimage, but the
result is always the same: no boot at all.
