[U-Boot] [PATCH V3 0/5] imx: Define common routines to set cpu and board environment variables

[Eric Nelson <eric.nelson@boundarydevices.com>]

This series adds support for two environment variables that are
useful for use in scripting startup of an O/S in general, and
specifically in computing DTB names.

Patches 1 and 2 implement the feature through arch_misc_init(), but
don't enable it.

Patch 3 overrides board_name for the nitrogen6x board file, which is
used for both Nitrogen6X and SABRE Lite boards.

Patch 4 enables the feature for nitrogen6x

Patch 5 enables the feature for Freescale mx6*sabre* boards

V3 reworks things completely based on feedback from the mailing list.
In particular:

--	the variable names were changes from "cpu" and "board" to
	"imx_type" and "board_name"
--	the arch_misc_init() routine was added
--	SABRE Lite environment was changed to use the feature

Eric Nelson (5):
  i.MX5x: define cpu_type() to return processor portion of cpu rev.
  imx: Define common routines to set cpu and board environment variables
  i.MX6: nitrogen6x/sabrelite: override set_board_name()
  i.MX6: nitrogen6x/sabrelite: initialize imx_type and board_name values
  i.MX6: mx6*sabre*: initialize imx_type and board_name values
