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

Hi Timur,

IMHO this would work only if the sum of
CFG_MONITOR_BASE + CFG_MONITOR_LEN is sector aligned.
Did you set CFG_MONITOR_LEN appropriately?
(Just to avoid unexpected behaviour)

Best regards
   Jens

I'm under the assumption that CFG_MONITOR_LEN is always supposed to be a 
multiple of the sector size.  Should I add comments to the header files to state 
that explicitly?

It's just, because I saw implementations, where CFG_MONITOR_LEN was an
arbitrary value. It depends on how the developer interpretes this
define and how it is used in the cpu and board specific code.

Maybe a comment would help, but I leave the decision to you.

Best regards
   Jens

The comment is clearly wrong. Thsi  does  not  apply  to  *all*  83xx
boards  (there is a whole world outside of FSL, actually). Please fix
and resubmit.

Best regards,

I said "all the 83xx boards", not "all 83xx" boards.  Technically, 
there's a difference.  However, I see your point and I will reword the 
comment.
