In order to use QMC mode in the CPM, a SCC requires more space
in parameter RAM.
After SCC1 there is I2C parameter RAM and after SCC2 there is
SPI parameter RAM. MPC866 and MPC885 can already relocate I2C and.
SPI parameter RAM.
But in order to free space after SCC3 and SCC4, SMC1 and SMC2
need to be relocated. In order to do so, a CPM microcode patch
is required.
Binary data for that patch is copied from Linux kernel.

MPC885 CPU has the following ERRATA:
When the USB controller is configured in Host mode, and the
SOF generation (SFTE=1 in USMOD register) is being used,
there may be false CRC error indication in other SCCs.
Although the data is received correctly, the CRC result
will be corrupted.

Using SMC relocation microcode patch or USB-SOF microcode patch
will disable DPRAM memory from 0x2000 to 0x2400 and from 0x2f00
to 0x3000.
At the time being, init RAM is setup to use 0x2800-0x2e00, but
the stack pointer goes beyond 0x2800 and even beyond 0x2400.
For the time being we are not going to use any microcode patch
that uses memory about 0x3000, so reorganise setup to use:
- 0x2800 - 0x2e00 for init malloc and global data and CPM buffers
- 0x3000 - 0x3c00 for init stack

This pull request adds support for the last CPU board from
CS GROUP France (previously CSSI).
That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence
its name) and can be plugged in place of the CMPC885 board.
In order to support that new board, the following changes are included
in this series:
- Make the mpc8xx watchdog driver more generic for reusing it
with mpc83xx
- Fix various small problems on mpc83xx platform
- Add a GPIO Driver for QE GPIOs
- Add support for mpc832x into mpc83xx SPI driver
- Refactor existing board code that will be shared with new board
- Add the new board
CSSI has another CPU board, similar to the CMPC885 board
that get plugged on the two base boards MCR3000_2G and MIAE.
That CPU board is called CMPCPRO because it has a MPC8321E CPU,
also known as Power QUICC II PRO.

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.

The event framework is just that, a framework. Enabling it by itself
does nothing, so we shouldn't ask the user about it. Reword (and correct
typos) around this the option and help text. This also applies to
DM_EVENT and EVENT_DYNAMIC. Only EVENT_DEBUG and CMD_EVENT should be
visible to the user to select, when EVENT is selected.
With this, it's time to address the larger problems. When functionality
uses events, typically via EVENT_SPY, the appropriate framework then
must be select'd and NOT imply'd. As the functionality will cease to
work (and so, platforms will fail to boot) this is non-optional and
where select is appropriate. Audit the current users of EVENT_SPY to
have a more fine-grained approach to select'ing the framework where
used. Also ensure the current users of event_register and also select
EVENT_DYNAMIC.

U-Boot build system builds final U-Boot binary for socrates board in custom

file u-boot-socrates.bin is generated by binman as defined in board binman
config file arch/powerpc/dts/socrates-u-boot.dtsi.
But binman was disabled in commit 5af42eafd7 ("Makefile: Reduce usage of
custom mpc85xx u-boot.bin target") for all mpc85xx boards which do not use
standard powerpc binman config file arch/powerpc/dts/u-boot.dtsi and boards
which do not require binman at all.
The only such mpc85xx board is socrates. So since that commit, U-Boot does
not final binary for socrates board anymore.
Fix this issue by re-enabling binman for socrates board. And build process
starts again producing u-boot-socrates.bin binary.
Note that build process for this socrates board always produce u-boot.bin
binary which is broken and not usable for socrates board. Long term
solution should be to disable building broken binary u-boot.bin and then
renaming u-boot-socrates.bin to u-boot.bin, or switching to use common
powerpc binman config file arch/powerpc/dts/socrates-u-boot.dtsi (if it is
