[U-Boot] [PATCH 0/7] Add Device Tree for OMAP3 and omap3_logic

[Adam Ford]

This patch series copies the Linux Device trees for the OMAP3 and
OMAP3630 platforms as well as some additional device trees to support
the Logic PD Torpedo and Logic PD SOM-LV both based on DM3730
(OMAP3630) processors.  There are no changes to patches 2-7 from the
initial version posted as RFC, but I added "Reviewed-by: Lokesh Vutla
<lokeshvutla at ti.com>" to patches 2-7

Patch 1 removes the wrong comments I made when mixed up the am33xx
datasheet.  It should correctly supports the proper offsets on the
OMAP34XX platforms and should not break the am33xx and newer boards
with the different offset.  I don't believe there is any debate on
this.  Sorry for the noise.

This series allows us to eliminate the board detection code as well as
move to DM_I2C and DM_MMC and push the DM_SERIAL setup to the OF
except when in SPL.  This should give enough background for other
OMAP3 boards to migrate to device tree.
