d9d77a5209 configs: pico-imx6ul: convert DM_VIDEO
It's due to the warning messages issue after compiled:

  ===================== WARNING ======================
  This board does not use CONFIG_DM_VIDEO Please update
  the board to use CONFIG_DM_VIDEO before the v2019.07 release.
  Failure to update by the deadline may result in board removal.
  See doc/driver-model/migration.rst for more info.
  ====================================================

Enable DM_VIDEO can fix it on the stage of compilation.

4b44bea701 ARM: imx: Add support for reading out the primary/secondary bmode to MX7
Implement the 'getprisec' subcommand of 'bmode' command for i.MX7 by
reading out the SRC GPR10 bit 30. This bit is either set by the BootROM
if it switched to the secondary copy due to primary copy being corrupted
OR it can be overridden by the user.

Add new 'getprisec' subcommand to 'bmode' command, which sets the return
value of the 'bmode' command to either 0 if the system booted from primary
copy or to 1 if the system booted from secondary copy. This can be used
e.g. in 'test' command to determine which copy of the system is running.

5ec83561c4 ARM: imx: Add support for switching primary/secondary boot mode to bmode
The i.MX6/i.MX7 is capable of booting a secondary "redundant" system
image in case the primary one is corrupted. The user can force this
boot mode as well by explicitly setting SRC GPR10 bit 30. This can be
potentially useful when upgrading the bootloader itself. Expose this
functionality to the user.

52956e535e efi_loader: signature: correct a behavior against multiple signatures
Under the current implementation, all the signatures, if any, in
a signed image must be verified before loading it.

Meanwhile, UEFI specification v2.8b section 32.5.3.3 says,
    Multiple signatures are allowed to exist in the binary’s certificate
    table (as per PE/COFF Section “Attribute Certificate Table”). Only
    one hash or signature is required to be present in db in order to pass
    validation, so long as neither the SHA-256 hash of the binary nor any
    present signature is reflected in dbx.

This patch makes the semantics of signature verification compliant with
the specification mentioned above.

If an exception occurs in an UEFI binary additionally the load addresses of
the UEFI binaries are needed. With this patch:

    => setenv efi_selftest exception
    => bootefi selftest

    Unhandled exception: Illegal instruction

db3585d181 cmd: exception: unaligned data access on RISC-V
The command 'exception' can be used to test the handling of exceptions.

Currently the exception command only allows to create an illegal
instruction exception on RISC-V.

Provide a sub-command 'exception unaligned' to cause a misaligned load
address exception.

Adjust the online help for 'exception undefined'.
