Pull request for UEFI sub-system for efi-2020-10-rc1 (4)

Improvements for the UEFI subsystem include:

* support for read-only TEE-backed variables
* allow to compile PK, KEK, db, dbx fixed values into U-Boot
* bug fixes

Python testing related changes comprise:

* enable 'bootefi hello' for better test coverage
* remove SKIP messages in UEFI Python tests

The fitupd command is dropped.
Build errors for the lsblk command are fixed.

Commit 45032991 has a side effect on this board, and build is broken.
Adjust mx6memcal_defconfig to build it again.

Currently default output of 'printenv -e' is restricted to variables with
GUID EFI_GLOBAL_VARIABLE. This excludes db and dbx. As the number of
variables is small there is no need for this restriction.

If no GUID is provided, print all matching variables irrespective of GUID.

Always show the numeric value of the GUID.

If the GUID provided to 'setenv -e' is invalid, return CMD_RET_USAGE.

To determine if a varible is on the of the authentication variables

As explained in the CONFIG_DM_MDIO text inside drivers/net/Kconfig:

"Useful in particular for systems that support
DM_ETH and have a stand-alone MDIO hardware block shared by multiple
Ethernet interfaces."

i.MX6 has a single FEC instance, so there is no need to select
CONFIG_DM_MDIO.

This commit enables imx28 based XEA board's u-boot.sb (SPL) to download
u-boot proper (u-boot.img) via Ymodem protocol.

This is extremely useful in the recovery scenario where u-boot.sb is
downloaded via uuu utility to SDRAM [*], and then one can upload u-boot
proper via serial console to fully debrick the device.

Note - debricking procedure of imx28 devices:
- NXP's original USB based tools (like mxsldr or uuu) expect single
  u-boot.sb which is a relic of the old U-Boot (~2013) without SPL and
  U-Boot proper distinction.

[*] On Host:
------------
cat << EOF > imx28_xea.lst
uuu_version 1.3.0
SDPS: boot -f /srv/tftp/xea/u-boot.sb
SDPU: done
EOF

Please start picocom:
sudo picocom -b 115200 -s "sz -vv" /dev/ttyUSB1
sudo ./uuu/uuu -V imx28_xea.lst

On the U-boot console one shall see:
Trying to boot from UART

Then please press CTRL+A, S
and type u-boot.img

After "4b969dea watchdog: imx: Add DM support", the imx watchdog
can be started by wdt command. But the imx watchdog driver only
support start with the default timeout.

This commit adds the support for setting the timeout which pass from
the wdt command into the imx watchdog. If the timeout out of the
valid range(0.5~128s), start the watchdog with a timeout within the
valid range and the timeout is the one which closest to the passed

Current mxc_gpio DM driver allocates the platdata in bind function to
handle both OF_CONTROL enabled case and disabled case. This implementation
puts the devfdt_get_addr in bind, which introduces much overhead especially
in board_f phase.

Change the driver to a common way for handling the cases by using
ofdata_to_platdata and using DM framework to allocate platdata.

i.MX platforms provide large AHB mapped space for QSPI, each
controller has 256MB. However, current driver only maps small
size (AHB buffer size) of AHB space, this implementation
causes i.MX failed to boot M4 with QSPI XIP image.

Add config CONFIG_FSL_QSPI_AHB_FULL_MAP (default enabled for i.MX)
to address above problem.

When the config is set:
1. Full AHB space is divided to each CS.
2. A dedicated LUT entry is used for AHB read only.
3. The MODE instruction in LUT is replaced to standard ADDR instruction
4. The address in spi_mem_op is used to SFAR and AHB read
