[U-Boot] [PATCH 1/2] powerpc/p1022ds: add support for SPI and SD boot

[Timur Tabi]

From: Matthew McClintock <msm@freescale.com>

Add TLB mappings, board target options, and configuration items
need for SPI/SD boot.

Since P1022DS RevB board, the NOR flash have been changed to 16 bit/28bit
address flash, therefore, when SDHC/ESPI booting and access to eLBC,
the PMUXCR[0~1] must be set to 10b, and PMUXCR[9~10] must be set to
00b for them.

Configure the PX_BRDCFG0[0~1] to 10b which is connected to
SPI devices as SPI_CS(0:3)_B.

What's this doing in the SPI/SD patch?

NACK, please use SPD.

Also please use the new SPL infrastructure.

I'm just taking the patches as they are on the SDK and posting them.  I
have no idea how the new SPL infrastructure works.

If you're going to NACK this patch set, then I'm just going to drop them
and work on something else.

Upstream would need these... it's not trivial task.

My best guess on a patch from months ago is just trying to keep things
in sync with other boards.
