The AUTO_RESTART flag of HW_RTC_PERSISTENT0 register will
power up the chip automatically 180ms after power down.
This bit must be enabled by the boot loader to ensure the
target can start upon hardware reset or watchdog reset
even when powered from a battery.
Currently the function named 'mxs_power_clear_auto_restart()'
is setting this flag although the 'clear' in its name suggest
the opposite.
This patch renames the function to 'mxs_power_set_auto_restart()'
and removes the comment about EVK revision A which was confusing
because the function indeed was setting the flag.

Add mkimage support for generating and verifying MXS bootstream.
The implementation here is mostly a glue code between MXSSB v0.4
and mkimage, but the long-term goal is to rectify this and merge
MXSSB with mkimage more tightly. Once this code is properly in
U-Boot, MXSSB shall be deprecated in favor of mkimage-mxsimage
support.
Note that the mxsimage generator needs libcrypto from OpenSSL, I
therefore enabled the libcrypto/libssl unconditionally.

Add support for setting the CSF (Command Sequence File) pointer
which is used for HAB (High Assurance Boot) in the imximage by
adding e.g.
CSF 0x2000
in the imximage.cfg file.
This will set the CSF pointer accordingly just after the padded
data image area. The boot_data.length is adjusted with the
value from the imximage.cfg config file.
The resulting u-boot.imx can be signed with the FSL HAB tooling.
The generated CSF block needs to be appended to the u-boot.imx.

The BeagleBone Black differs from the other AM335x boards in a few
significant ways, so it makes sense to create a custom configuration
for it. In particular, it uses eMMC instead of NAND flash.
Signed-off-by: Justin Waters <justin.waters@timesys.com>
Some boards, such as the BeagleBone Black, have an eMMC chip intstead
of NAND. We can use the eMMC boot partition to store the environment,
since it isn't used for anything else. This allows us to have a
configurable environment on those boards.

The BeagleBone Black can boot from either the MMC card

NOR requires that s_init be within the first 4KiB of the image so that
we can perform the rest of the required pinmuxing to talk with the rest
of NOR that we are found on. When NOR_BOOT is set we save our
environment in NOR at 512KiB and a redundant copy at 768KiB. We avoid
using SPL for this case and u-boot.bin is written directly to the start
of NOR.
We enclose the DMM-related parts of arch/arm/cpu/armv7/am33xx/emif4.c
with TI81xx checks as at this time U-Boot does not discard unused
sections in the main build and this code relies on functions specific to
(and only provided in) ti81xx-related code.

A little background is probably appropriate for this patch.
Since "the beginning" of usage of the SABRE Lite and Nitrogen6x
boards, DVI detection has been somewhat broken.
Some (most) DVI monitors don't produce the "HPD" bit in
the PHY_STAT0 register, but do show proper toggling of the
RX_SENSE0..3 bits.
Creating a new the bit-mask to include all five bits and
modifying the 'hdmidet' command and internal detection
routines allows these monitors to function properly in U-Boot.

If no other bootoption works, try loading up device tree and zImage.
This is selected as the last option to allow backward compatibility as
well as support the recent trend in moving kernel boot to using zImage
and device tree.
NOTE: if uImage is present in bootpart, it will try this first and
will assume this is to be booted with bootm (so may be concatenated
image or plain vanilla ATAG MACHINE_ID based image)

bootdir=/boot (/boot in second partition)
