[u-boot] hwo to setup ENV in compile time

Hi mountain8848,

Something that just caught my eye:

cmd=(vu_char *)0x555;//20051018:according AM29LV128 CFI commands

writeb (cmd, 0xaa);

If you're using the device in 16-bit mode, you have to change a few things.

When you port from the 065 to the 128, you have to change to vu_char to

vu_short, writeb()/readb() to writew()/readw(), etc.

But you might find it easier to grab an existing implementation (e.g. from the

tqm5200 or xsengine board tree). If you're not using a data cache you won't

have to worry about using writew/readw.

Regards,
