[U-Boot] [PATCH] AT91: Defer Dataflash access to env_relocate_spec

[Reinhard Meyer]

Dear Hong Xu,

I cannot really decide if that is a good approach. Where would be
the issue if SPI/dataflash were initialized at this point (before
relocation)?
Same works well for example for I2C.

If Wolfgang is OK with it, I can pick up this patch (once
it is agreed on the way to solve the issue).

Best Regards,
Reinhard
