  To: u-boot

Fix the definitions of CFG_ENV_ADDR and CFG_ENV_SECT_SIZE for all of the
currently-defined 83xx boards.  This change guarantees that the environment
will be located on the first flash sector after the U-Boot image.

No, this comment is definitely wrong.

You just touch some (Freescale) boards here. For exampole, you don't
touch the code for the TQM834x board.

Best regards,

Conceptual integrity in turn dictates that the  design  must  proceed
from  one  mind,  or  from  a  very small number of agreeing resonant

Sorry, I understand now.  I just kept thinking that "MPC83xx" == all 83xx.  I 
don't know what's wrong with me.

Applied to mpc83xx branch of u-boot-mpc83xx.

Please base your 83xx patches on this branch in the future (I handled
extending this patch to 837x this time).
