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.Signed-off-by: Hector Palacios

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.MXSSB: http://git.denx.de/?p=mxssb.git;a=summary
The code is based on research presented at:

Add functions to report the HAB (High Assurance Boot) status
of e.g. i.MX6 CPUs.This is taken from

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.Signed-off-by: Stefano Babic

Implement function vrec_header to be able to pad the final
data image file according the what has been calculated for
boot_data.length.Signed-off-by: Stefano Babic
-
Use previously unused return value of function vrec_header
to return a padding size to generic mkimage. This padding
size is used in copy_files to pad with zeros after copying
the data image.Signed-off-by: Stefano Babic
-
Change to dynamically allocate the imx_header to correctly
allocate the IVT, Boot Data and DCD at correct locations
depending on the boot media.Also check that the Image Vector Table Offset + IVT +
Boot Data + DCD -
This better reflects the naming from the Reference Manual
as well as fits better since "flash" is not really applicabe
for SATA.Signed-off-by: Stefano Babic

Our Linux kernel switches the HDMI connector onto IPU0/DI1,
but the U-Boot display driver only supports IPU0/DI0 for the
time being.Because of this, a soft re-boot will leave the HDMI output
connected to the wrong display port and prevent video from
being displayed.Signed-off-by: Eric Nelson

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
-
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.Signed-off-by: Justin Waters

The BeagleBone Black can boot from either the MMC card
or eMMC chip on board. We should try both interfaces.This modification also allows a graceful fallback if
a device exists but boot images are not present on it.Changes for v2:
* Fix boot partition - it should always show up as mmcblk0p2
* Fix missing FDT loadSigned-off-by: Justin Waters

Many modern U-Boot ports enable command line editing and

accessing a lan9303 switch with the cpsw driver results in wrong
speed detection, as the switch sets the BMSR_ERCAP in BMSR
register, and follow read of the MII_STAT1000 register fails, as
the switch does not support it. Current code did not check,
if a phy_read() fails ... fix this.Signed-off-by: Heiko Schocher

The Beaglebone White may be populated with a memory cape that has a NOR
module. Document how to program it.Signed-off-by: Tom Rini
-
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.Cc: Albert ARIBAUD

We rework the various board_is_foo() checks to take a pointer to
struct am335x_baseboard_id rather than using a local copy in board.c.

problems when this code could be running from read-only memory.Reviewed-by: Peter Korsgaard

- Style cleanup (# define -> #define)
- Due to ROM issues, redudant loading isn't feasible, so drop.
- Given extra space, increase max size of U-Boot to 512KiB
- Correct env size to match usage (we had not re-defined ENV_SIZE).
- Given extra space, keep env size as 128KiB, add redundant environment.Reviewed-by: Peter Korsgaard

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.A related patch to our kernels allows things to work under
Linux:
