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.

We have existing entries for this option in a number of places, with
different guards on them. They're also sometimes used for things not
directly inside of the serial driver. First, introduce a new symbol to
guard the use of CONFIG_CONS_INDEX, so that in the case where we don't
need this for the serial driver, but for some other use, we can still do
it. Next, consolidate all of these into the single entry in

Move this option out of mach-omap2 Kconfig to a spot accessible by both

location as this option is not specific to our boards but rather our

This patch adds support for authentication of both plain
text and encrypted binaries. A new SECDEV package is needed
to enable encryption of binaries by default for AM3x.
The ROM authentication API detects encrypted images at
runtime and automatically decrypts the image if the
signature verification passes.
Addition of encryption on AM3x results in a change in the
image format. On AM4x, AM5x and, on AM3x devices signing
clear test images, the signature is appended to the end of the
binary.
On AM3x, when the SECDEV package is used to create signed
and encrypted images, the signature is added as a header
to the start of the binary. So the binary size calculation
has been updated to reflect this change.
The signing tools and encrypted image format for AM3x
cannot be changed to behave like AM4x and AM5x to
maintain backward compatibility with older Sitara
M-Shield releases.
