I cannot comment much on this code as I have no access to any hardware
with such a device, but here are a few formal comments:

This line is probably missing some additional indentation?

I'm not happy with the parameter format of the "erase"  and  "unlock"
commands  -  using  an  address  specification  of "start-end" breaks
existing conventions in U-Boot. Please  use  two  separate  arguments
instead.

Also, I don;t see what  the  difference  between  "erase  block"  and
"erase"  is  -  can  we  avoid  "erase block" all together? If not, I
recommend to  change  it  into  "eraseblock"  (which  could  then  be
shortened to "eraseb") to avoid too different command formats.


After changing this, you have my ACK.

Thanks a lot.

Best regards,

Wolfgang Denk

In the beginning there was nothing.
And the Lord said "Let There Be Light!"
And still there was nothing, but at least now you could see it.
