AM43xx Starter Kit is a new board based on
AM437x line of SoCs. Being a low-cost EVM and
small size EVM are intended to provide an entry
level development platform on a full fledged
Hardware System.

This family is supported by the TPS65218 PMIC.  Implement a scale_vcores
to set the MPU and CORE voltage correctly to the max frequency that is
supported (and what we will be scaling them to in setup_dplls()).

loadbootenv expects devtype variable to be set. This is missing in
mmcboot command. With this the following error comes:
U-Boot# run mmcboot
mmc0 is current device
SD/MMC found on device 0
** Bad device usb 0 **
** Bad device usb 0 **
Fixing this by setting devtype as mmc.

With the changes to the i2c framework (and adopting the omap24xx_i2c
driver to them) we can no longer call i2c functions prior to gd having
been set and cleared.  When SPL booting, this is handled by setting gd
to point to SRAM in s_init.  However in the cases where we are loaded
directly by ROM (memory mapped NOR or QSPI) we need to make use of the
normal hooks to slightly delay these calls.

The ePOS EVM and EVM SK have QSPI as an option to boot.  Add a qspiboot
target that utilizes QSPI for env and so forth as an example of best
practices.  As QSPI is booted from directly we need to chang
CONFIG_SYS_TEXT_BASE.

Note that on ePOS EVM the QSPI and NAND are mutually exclusive choices
we need to handle that elsewhere, once NAND support is also added.

QSPI booting on this board does not use SPL, so drop SPI-SPL related

In general, we want to load the DT at base+128MB, so that we ahve
sufficient room for the kernel and a larger device tree.  In the case of
OMAP3, use 64MB instead as we have a number of boards with 128MB DDR.

To deal with a reoccurring problem properly we need to specify addresses
for the Linux kernel, Flatted Device Tree and ramdisk that obey the
constraints within the kernel's Documentation/arm/Booting file but also
make sure that we relocate things within a valid address range.

It is possible with these addresses to also set fdt_high and initrd_high
to the value of 0xffffffff.  We don't do this by default to allow for
the most likely success of people using custom addresses however.
