1e0d51a6c4 powerpc: mpc85xx: Implement CPU erratum A-007907 for secondary cores
Commit 06ad970b53 ("powerpc: mpc85xx: Implemente workaround for CPU
erratum A-007907") clears L1CSR2 for the boot core, but other cores
don't run through the workaround. Add similar code for secondary
cores to clear DCSTASHID field in L1CSR2 register.

ae07d609e9 powerpc: Use asm-generic/io.h
Convert the powerpc architecture to make use of the new asm-generic/io.h
to provide address mapping functions. As powerpc can actually perform
non-identity mapping between physical & virtual addresses we can't
simply make use of the generic phys_to_virt() & virt_to_phys()
functions. However since map_physmem() already effectively implemented
the same thing as virt_to_phys() we can simply implement virt_to_phys()
instead of map_physmem() & use the generic map_physmem(). We also drop
the no-op unmap_physmem().

This has only been build-tested, feedback from architecture maintainers
is welcome.

c1c3fe2307 env: Convert CONFIG_ENV_IS_IN... to a choice
At present we support multiple environment drivers but there is not way to
select between them at run time. Also settings related to the position and
size of the environment area are global (i.e. apply to all locations).

Until these limitations are removed we cannot really support more than one
environment location. Adjust the location to be a choice so that only one
can be selected. By default the environment is 'nowhere', meaning that the
environment exists only in memory and cannot be saved.

Also expand the help for the 'nowhere' option and move it to the top since
it is the default.

2b71d098ee powerpc: spl: configure SYS_MALLOC_F_LEN independently for SPL and full U-Boot
Some platforms have very limited SRAM to run SPL code, so there may
not be the same amount space for a malloc pool before relocation in
the SPL stage as the normal U-Boot stage.

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN,
so the size of pre-relocation malloc pool can be configured memory
space independently.

f3603b4382 powerpc: Remove unneccessary #ifdefs in reginfo
reginfo command is calling mpc8xx_reginfo(), mpc85xx_reginfo()
or mpc86xx_reginfo() based on CONFIG_ symbol.
As those 3 functions can't me defined at the same time, let's
rename them print_reginfo() to avoid the #ifdefs
The name is kept generic as it is not at all dependent on
powerpc arch and any other arch could want to also print
such information.

In addition, as the Makefile compiles cmd/reginfo.c only when
CONFIG_CMD_REGINFO is set, there is no need to enclose the U_BOOT_CMD
definition inside a #ifdef CONFIG_CMD_REGINFO

Lets all remove the #ifdefs around the U_BOOT_CMD as this
file is only compiled when CONFIG_CMD_REGINFO is defined

Finally, this is a PowerPC-only command, disable it on a number of
non-PowerPC platforms.

907208c452 powerpc: Partialy restore core of mpc8xx
CS Systemes d'Information (CSSI) manufactures 8xx boards for
critical communication systems. Those boards have been
running U-Boot since 2010 and will have to be maintained
until at least 2027.

commit 5b8e76c35e
("powerpc, 8xx: remove support for 8xx") orphaned those boards
by removing support for the mpc8xx CPU.

This commit partially restores support for the 8xx, with the
following limitations:
- Restores support for MPC866 and MPC885 only
- Does not restore IDE, PCMCIA, I2C, USB
- Does not restore examples
- Does not restore POST
- Does not restore Ethernet on SCC
- Does not restore console on SCC
- Does not restore bedbug and kgdb support

As the 866 and 885 do not support the following features,
they are not restored either:
- VIDEO / LCD
- RTC clock

The CPM uCODE patch is not restored either, because:
- 866 and 885 already have support for I2C and SPI relocation
without a uCODE patch
- relocation of SMC, I2C or SPI is only needed for using SCCs
for Ethernet or QMC

The dynamic setup/calculation of clocks is removed, we
expect the target being use with the clock and PLPRCR register
defined in the configuration.
All the clock settings for 8xx prior to 866 is removed as
well as we now only support 866 and 885.

This code is mature and addresses mature boards. Therefore
all code enclosed in '#if 0/#endif' and '#if XX_DEBUG/#endif'
is unneeded.

The following files are not restored by this patch:

- arch/powerpc/cpu/mpc8xx/bedbug_860.c
- arch/powerpc/cpu/mpc8xx/fec.h
- arch/powerpc/cpu/mpc8xx/kgdb.S
- arch/powerpc/cpu/mpc8xx/plprcr_write.S

- post/cpu/mpc8xx/uart.c
- post/cpu/mpc8xx/usb.c
- post/cpu/mpc8xx/watchdog.c

Some of the restored files are not located in a proper location.
In order to keep traceability of the changes, they will be
moved to their correct location and moved to Kconfig in a
followup patch.

This patch also declares CSSI as point of contact for the update
of the 8xx platform, as those boards are the only ones still
being maintained on the 8xx area. A later patch will add
those boards to the tree.
