As the PHYTEC phyCORE-i.MX91 [1] is just another variant of the existing
PHYTEC phyCORE-i.MX93 SoM but with i.MX91 SoC populated instead, add it
to the existing board-code "phycore_imx93", and rename that board to
"phycore_imx91_93" to reflect the dual SoCs support. While at it, also
rename and change common files accordingly. This way i.MX91 and i.MX93
SoC variants of the phyCORE SoM share most of the code and documentation
without duplication, while maintaining own device-tree and defconfigs
for each CPU variant.
Supported features:
- 1GB LPDDR4 RAM
- Debug UART
- EEPROM
- eMMC
- Ethernet
- SD-card
- USB

Our last sync with the kernel was 5.1. Even that was a partial one
as some patches from 4.x kernels were already missing making the
transition to a modern kbuild infeasible.
We are so out of sync now, that tracking the patches and backporting
them one by one makes little sense and it's going to take ages.
This is an attempt to sync up Makefile[.lib/.kbuild].
Unfortunately due to sheer amount of patches this is not easy to review,
but that's what we decided during a community call.
One of the biggest changes is get rid of partial linking entirely and
build .a archives isntead of .o.
We diaviate from the kernel on that. Instead of calling a custom script
to create the archive symbol table, we call ar with rcTP (isntead of
rcSTP) since we want a resulting archive that's sauble with the linker.
The only affected platforms are PPC ones. Unfortunately I don't have any
of them around to test, but the objdump of the resulting files --
arch/powerpc/lib/built-in.[oa] looks identical.

The phyCORE-i.MX 93 is available in various variants. Relevant variant
options for the spl/u-boot are:
- with or without HS400 support for the eMMC
- with 1GB ram chip, or 2GB ram chip
The phyCORE's eeprom contains all information about the existing variant
options. Add evaluation of the eeprom data to the spl/u-boot to
enable/disable HS400 and to select the appropriate ram configuration at
startup.

This API is based on a block structure with a 8 Byte large
API v3 header and various of different blocks following. It extends
our current API v2, which is always 32 Byte large, and is located
directly after v2.
Add the MAC block as first block type. It contains the physical
Ehternet interface number, a MAC address and a CRC checksum over the
MAC payload.

As part of bringing the master branch back in to next, we need to allow

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.
This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Factor out code that we can reuse across all our K3 based SoMs.
2nd patch of this series require patch [1] to be applied first.

Environment handling code can be reused across all our K3 based SoMs.
Instead of adding the same code for every new SoM, move it to a common
board.c file.

Commit aa7858fe5e2e ("board: phytec: som_detection: move definitions to
source file") moved function definitions from header to source file.
Makefile however was not updated to unconditionally (from
[..]_SOM_DETECTION) build the imx8 and phytec som detection units.
Also remove unused includes that cause build failures on arm 32bit
boards. SoM detection shall support 32bit boards as well, but arch
specific code should not be included in the generic module.

Recent shipped PHYTEC SoMs come with an i2c EEPROM containing
information about the hardware such as board revision and variant.
This can be used for RAM detection and loading device tree overlays
during kernel start.
