On mpc832x, SPI can be either handled by CPU or QE.
In order to work in CPU mode, bit 17 of SPMODE has to
be set to 1, that bit is called OP.
Also, data is located at a different place than the one expected
by the driver today. In 8 bits mode with REV set, data to be
transmitted is located in the most significant byte while
received data is located in second byte. So perform the
necessary shifts.
In order to differentiate with other CPUs, a new compatible is
added for mpc832x: fsl,mpc832x-spi

At startup, some RAM is needed (for instance for stack) before
DRAM is initialised.
One way to offer such RAM, used by mpc83xx, is to lock some entries
in the cache. To do that, MMU needs to be activated.
On mpc83xx having a QUICC Engine an alternative is to user some
part of from the Multi User RAM, like done on mpc8xx for instance.
For that, the MMU is not needed.
Activating the MMU is problematic because exception vectors are not
setup yet so in case of ISI or DSI that CPU will crash and reboot.
At the time being, MMU is activated regardless.
Only activate it when locking cache entries to provide initial RAM.

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.

U-Boot can be booted from NAND without SPL by prepending the DCD header to
the actual U-Boot binary. However this requires prepending 1024 bytes to
u-boot.imx (DCD + u-boot.bin).
There is already a similar target to build spl/u-boot-nand-spl.imx, add the
same option for no-SPL boot.
Tested on i.MX6ULL.
The resulting layout of u-boot-nand.imx is:
- Offset 0x0000 (0 KiB): padding
- Offset 0x0400 (1 KiB): DCD header
- Offset 0x1000 (4 KiB): u-boot.bin

J721e SK has been broken since at least March 2022.
The main-navss and mcu-navss nodes were renamed and this caused the
A72 SPL to fail early in the boot even before the serial port was
enabled. Fix this.
A later patch series between v2022.07 and v2022.10 additionally broke
boot on this board by introducing hbmc nodes which are not present on
this board. The right fix is to disable these by default in the SOC
dtsi file, but for now we can also disable them in the u-boot dtsi.
With both these fixed, we can now boot the j721e SK board fully from
mainline u-boot.

Originally, the mmc aliases node was present in imx6qdl-pico.dtsi.
After the sync with Linux in commit d0399a46e7 ("imx6dl/imx6qdl:
synchronise device trees with linux"), the aliases node is gone as
the upstream version does not have it.
This causes a boot regression in which the eMMC card cannot be found anymore.
Fix it by passing the alias node in the u-boot.dtsi file to
restore the original behaviour where the eMMC (esdhc3) was
mapped to mmc0.

The DWMAC clock in i.MX8M Plus were so far configured via ad-hoc
architecture code. Replace that with DM clock instead. This way,
the driver claims all its required clock, enables and disables
them, and even gets the CSR clock rate and sets the TX clock rate,
without any need of architecture specific register fiddling. Drop
the architecture specific code while at it too.
The adjustment here is modeled after STM32MP15xx clock handling
