It would really be great if someone cold clean up this mess in
"include/fsl_pmic.h"

Using an "enum" for register definitions is just horrible.

I am well aware that you did not introduce this code, but reading this
feels is if my nails are rolling up.

Don't you feel the need to intr=oduce some readable symbolic
constants for all these magic numbers here?

We don't accept register base plus offset notation any more. Please
use a C struct to describe the register layout.  Please fix globally.

Indentation by TAB only, please. [Check & fix globally, please.]

NAK!!

We do not allow network parameters in the default environment (and
especially not broken/incorrect MAC addresses.

Do you think it makes any sense to your customers to encode your local
settings like "/srv/home/david/Devel/Sandboxes/LEL/XDH/nfsroot" in the
default environment?

I doubt that.

Is this really needed on your hardware?

Please use TABs for vertical alignment.

Hi David,

in addition to Wolfgang's comments:

> +struct io_board_ctrl *mx51_io_board;

Structure is not used, and probably does not match your board. You
should drop it.

Consider to put these defines in include/asm/arch-mx51/iomux.h. They
could be usefult for other boards, too.

Comment is misleading. Remove what is not needed.

Add spaces when needed.

> +#ifdef BOARD_LATE_INIT

Probably it is better (and in mx51evk, too) to remove the #ifdef,
because we need to initialize the pmic, else some functionalities cannot
work. It is mandatory that power_init is called.

Is this structure really used ? I have not seen in code. Or does it come
only from mx51evk ? You can remove the whole file, if it is not needed.
