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.

MCR boards are plugged in racks. The position in the rack can be read
in a register.
For MCR3000, that's provided by the FPGA so check it is loaded before
reading the address.
For the other boards, the FPGA is loaded by hardware so it can be
read inconditionnaly.

Unlike CMPC885 and CMPCPRO boards, the FPGA of MCR3000 board doesn't
load code automatically but needs to be loaded by software through SPI.
Until now it was loaded later by Linux, but we'd like U-boot to have
access to some information that require the FPGA, like board address
in racks.
So, implemented the load of FPGA in U-boot.

MCR3000 board has some components tied to the SPI bus, like the Texas
Instruments LM74 temperature sensor.
Add support for SPI bus. The SPI chipselects are a bit special in the
way that they are driven by 3 bits in a register of the board's CPLD
where the value writen in those bits exclusively activates one of the
7 possible chipselects and value 0 sets all chipselets to inactive.
So add a special GPIO driver that simulates GPIOs for those chipselect.

mpc8xx, mpc83xx and mpc86xx have similar watchdog with almost same
memory registers.
Refactor the driver to get the register addresses from the
device tree and use the compatible to know the prescale factor.
Calculate the watchdog setup value from the provided timeout.
Don't declare it anymore as an HW_WATCHDOG, u-boot will start
servicing the watchdog early enough.
On mpc8xx the watchdog configuration register is also used for
configuring the bus monitor. So add it as an option to the watchdog
when it is mpc8xx. When watchdog is not selected, leave the
configuration of the initial SYPCR from Kconfig.

version
Both U-boot and Linux kernel have grown over the last releases
and don't fit anymore in the 2M EPROM of the board.
So, rework the setup to allow storing the Linux kernel image
on the UBIFS NAND Flash.
Also add support to FIT images as this is what the Linux kernel
look like nowadays.
Also increase CFG_SYS_BOOTMAPSZ to 32Mbytes and define
CONFIG_SYS_BOOTM_LEN with the same value, otherwise it defaults
to 8M which is not sufficient anymore with nowadays Linux kernels.
And set the netmask to 255.255.255.0 as a class C address is used.

We can move all of the environment changes to come
from CONFIG_EXTRA_ENV_TEXT.
