[U-Boot] [PATCH] OMAP3EVM: net_chip uses CS5 not CS6

[Matthias Ludwig]

Wolfgang, Dirk,

cause for this patch was originally the plan to bring my company's new
omap3-based platform into U-Boot. As we do use other CS for a network
chip this patch was intended to be the starting point (otherwise our
patchset will not apply).

I can prepare a big #define -> c_struct patch for omap next week.
The only problem i see, my following patches will be rebased onto that
and will only apply after the transition #define -> c_struct is done.

If this is ok for you i will submit this mid/end of next week.

best regards,
Matthias
