[ELDK] MPC5200B in large flash mode

Hi All,
We have a custom MPC5200B board using large flash mode (hence no
PCI/ATA), otherwise it is very similar to the Lite5200. The kernel is
configured using lite5200_defconfig with PCI disabled.
We have not found another design that uses large flash mode as a
reference, maybe there is more kernel configuration we have to do.
uboot's tftp works fine; however, we find that NFS mount (and
networking generally) is very slow in the kernel. The server is ok as
a Lite5200 using the same NFS mount works. Please see the serial
output below.
We are interested in any person/company we could contract to fix the
problem.
