[U-Boot-Users] saveenv to flash for MPC8360ERDK evaluation board.

Hi,

I am trying to update the u-boot for the LogicPD/Freescale MPC8360ERDK 
evaluation board and found some problems with saving the environment 
configurations to flash.

What I found is that in u-boot 1.3.2 the saveenv command works ok, but 
since u-boot 1.3.3-rc1 (and I suspect later version) the command does 
not save the environment variable.

from the git-trees, I rolled back /drivers/mtd/cfi_flash.c to the u-boot 
1.3.2 version and now the saveenv command seems to work again.

I think some change in there (maybe cmd_set_amd_read_jedec_ids, when 
info->device_id is populated)
causes the flash writing mishap.

Have anyone else experienced this as well?

Any suggestions are also welcome.

Thank you,

Richard Retanubun

When nobody can answer in a general fashion, it is time to crank up
git-bisect(1) and identify the one single commit breaking the
functionality.  Once you have that located, it may be pretty obvious
what is going wrong.
