Those are the parameters for the chip select timings on the expansion
bus. Since the IXP port does no supply useful defines for these bits, I
had to use magics there (however, even defines would only be readable if
you have the datasheet open at the same time).

This is basically just existing code that is moved around.

Unfortunately, yes, because the environment sector is embedded inside
the u-boot image.
