[U-Boot] [PATCH V2 0/3] i.MX6: mx6qsabrelite: allow use with Freescale 2.6.38 kernels

[Eric Nelson]

	This series of patches is needed to allow main-line U-Boot to be used
	with Freescale's Linux 2.6.38 non-DT kernel releases.

	These releases currently require at least the machine type and
	revision atag entries and are configured to load boot scripts from
	the ext3 filesystem.

	V2 just simplifies patch 2/3 to use CONFIG_MACH_TYPE instead of
	updating mach-types.h and filling things in during boot.

	Three new declarations in the board-specific header and one
	new routine in the board-specific file seem like a low cost
	to add a "U" (Universal) to main-line U-Boot.

	Eric Nelson (3):
	  i.MX6: mx6q_sabrelite: add CONFIG_REVISION_TAG to allow use with
	    Freescale kernels
	  i.MX6: mx6qsabrelite: add MACH_TYPE_MX6Q_SABRELITE
	  i.MX6: mx6qsabrelite: add ext2 support

Applied to u-boot-imx, thanks.
