Kernel stores information to the RTC_SCRATCH0 and RTC_SCRATCH1 registers
for wakeup from RTC-only mode with DDR in self-refresh. Parse these
registers during SPL boot and jump to the kernel resume vector if the
device is waking up from RTC-only modewith DDR in Self-refresh.
The RTC scratch register layout used is:
SCRATCH0 : bits00-31 : kernel resume address
SCRATCH1 : bits00-15 : RTC magic value used to detect valid config
SCRATCH1 : bits16-31 : board type information populated by bootloader
During the normal boot path the SCRATCH1 : bits16-31 are updated with
the eeprom read board type data. In the rtc_only boot path the rtc
scratchpad register is read and the board type is determined and
correspondingly ddr dpll parameters are set. This is done so as to avoid
costly i2c read to eeprom.
RTC-only +DRR in self-refresh mode support is currently only enabled for
am43xx_evm_rtconly_config.
This is not to be used with epos evm builds.

Almost all users of CONFIG_AM33XX/AM43XX have been migrated. Finish
moving the last few over to Kconfig, and put all of the boards under the
appropriate Kconfig chocie now. This board choice is non-optional, so
remove that keyword on am33xx.

The symbol CONFIG_TI81XX is used for the parts that are common to the
TI816x and TI814x SoCs and are not part of CONFIG_ARCH_OMAP2PLUS nor
CONFIG_AM33XX. It however has so few uses that we can just modify the
code to check for both and drop the symbol. The symbols CONFIG_TI816X
and CONFIG_TI814X are for the repective SoCs.

chiliSOM is a System On Module (http://http://grinn-global.com/chilisom/).
It can't exists on its own, but will be used as part of other boards.
Hardware specification:
* TI AM335x processor
* 128M, 256M or 512M DDR3 memory
* up to 256M NAND
We place source inside arch/arm/mach-omap2/ directory and make it
possible to reuse initialization code (i.e. DDR, NAND init) for all
boards that use it.

The SPL load address changes based on boot type in HS devices,
ISW_ENTRY_ADDR is used to set this address for AM43xx based SoCs
for similar reasons. Add this same logic for AM33xx devices.
Also make the default value for ISW_ENTRY_ADDR correct for GP
devices based on SoC, HS devices already pick the correct
value in their defconfig.

This moves what was in arch/arm/cpu/armv7/omap-common in to
arch/arm/mach-omap2 and moves
arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2
as subdirectories. All refernces to the former locations are updated to
the current locations. For the logic to decide what our outputs are,
consolidate the tests into a single config.mk rather than including 4.
