455f55e4a3 arm: mvebu: turris_omnia: Show MCU version
There are already more MCU firmware versions for Turris Omnia in
production, so display git commit (version) of the MCU firmware during
U-Boot startup. It will help to identify what version of MCU firmware is
Turris Omnia using.

MCU firmware for Turris Omnia is open source and available at website:
https://gitlab.nic.cz/turris/hw/omnia_hw_ctrl

It can be updated from running system via i2c bus with this tool:
https://gitlab.nic.cz/turris/omnia-mcutool

5a86d67e31 arm: kirkwood: pogo_v4: Add Distro boot capability
- Add distro boot to board include file and deconfig file
- Miscellaneous changes:
	- Add CONFIG_SUPPORT_PASSING_ATAGS and friends to support legacy
	kernel method of booting (e.g. OpenWrt) with appended DTB.
	- Add CONFIG_LTO and CONFIG_UBIFS_SILENCE_MSG, and disable some
	unused configs	to reduce binary size.

Note that this patch is depended on the following patch:

397626ced6 arm: mvebu: Define env_sf_get_env_addr() for all Armada boards in SPL
SPI0 CS0 Flash is mapped to address range 0xD4000000 - 0xD7FFFFFF by BootROM.
Proper U-Boot removes this direct mapping. So it is available only in SPL.
This applies for all 32-bit Armada BootROMs. SPL mvebu code is used only on
32-bit Armada SoCs. So move env_sf_get_env_addr() function from Turris
Omnia board to common SPL mvebu code and add proper checks for SPI0 CS0.

b6d4e0850b CI: Move to Ubuntu 2022.04 "Jammy" for CI base
- We now have a new enough sbsigntools in the distro, stop building.
- Use the 20220801 tag for Jammy.
- Move to pygit2 1.9.2 (current version) as the old one doesn't build on
 "Jammy".
- Add the working directory to the list of safe directories for git.
- Move to pytest 6.2.5 to address other issues.
- This move exposed a number of minor issues in the existing scripts we
  used within CI to perform the jobs themselves.  The most notable changes
  here involve using 'set +e / set -e' to enforce when we should or should
  not make non-zero buildman status be a fatal error.

080b7d89ae mtd: rawnand: fsl_elbc: Remove NAND_NO_SUBPAGE_WRITE flag
Subpage write support for freescale eLBC NAND controller driver is
implemented in U-Boot and was fixes in the commit d3963721d9 ("nand: Sync
with Linux v4.1").

So remove NAND_NO_SUBPAGE_WRITE flag from the fsl_elbc_nand.c driver. This
partially revert commit cb04c77234 ("nand/fsl: add NAND_NO_SUBPAGE_WRITE
to eLBC and IFC drivers"), only eLBC driver part.

With this change U-Boot with default settings can read from NAND UBIFS
image created on Linux with Linux default settings. Prior this change
U-Boot was unable to read from NAND UBIFS images created with Linux default
settings due to differnet UBI geometry.

Linux kernel fsl_elbc_nand.c driver also does not set NAND_NO_SUBPAGE_WRITE
flag and has implemented subpage write support.

Fixes: cb04c77234 ("nand/fsl: add NAND_NO_SUBPAGE_WRITE to eLBC and IFC drivers")

007f1d1473 mtd: nand: samsung: Retrieve ECC requirements from extended
Upstream linux commit 8fc82d456e40a0.

On some nand controllers with hw-ecc the controller code wants to know
the ecc strength and size and having these as 0, 0 is not accepted.

Specifying these in devicetree is possible but undesirable as the nand
may be different in different production runs of the same board, so it
is better to get this info from the nand id where possible.

This commit adds code to read the ecc strength and size from the nand
for Samsung extended-id nands. This code is based on the info for the 5th
id byte in the datasheets for the following Samsung nands: K9GAG08U0E,
K9GAG08U0F, K9GAG08X0D, K9GBG08U0A, K9GBG08U0B. These all use these bits
in the exact same way.

94633c36f9 net: Make DM_ETH be selected by NETDEVICE
The deadline for DM_ETH migration passed 2 years ago.  Now that
platforms which cannot be migrated have been either removed or had
drivers disabled, and platforms that needed minor help to migrate have
been forcefully migrated, we can complete the migration.

This entails select'ing DM_ETH under NETDEVICES, and then removing now
extraneous depends on lines.  In a few places, we can now either remove
options or just simplify later dependencies.

4f463e3dee binman: Remove obsolete compressed data header handling

to compress and decompress data. The header is uncommon, not supported
by U-Boot and incompatible with external compressed artifacts.

9f74395ee5 binman: Disable compressed data header
Disable the compressed data header of the utilities to compress and
decompress data. The header is uncommon, not supported by U-Boot and
incompatible with external compressed artifacts.

The header was introduced as part of commit eb0f4a4cb4 ("binman:
Support replacing data in a cbfs") to allow device tree entries to be
larger than the compressed contents.

6aa8000e74 binman: Add length header attribute to dtb entry
Add an optional length header attribute to the device tree blob entry
class based on the compressed data header from the utilities to compress
and decompress data.

If needed the header could be enabled with the following
attribute beside the compress attribute:
  prepend = "length";

The header was introduced as part of commit eb0f4a4cb4 ("binman:
Support replacing data in a cbfs") to allow device tree entries to be
larger than the compressed contents. Regarding the commit "this is
necessary to cope with a compressed device tree being updated in such a
way that it shrinks after the entry size is already set (an obscure
case)". This case need to be fixed without influence any compressed data
by itself.
