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.

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.

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 5b8e76c35ec312a3f73126bd1a2d2c0965b98a9f
("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

- 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.

Commit 94e3c8c4fd7b ("crypto/fsl - Add progressive hashing support
using hardware acceleration.") created entries for CONFIG_SHA1,
CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL.
However, no defconfig has migrated to it. Complete the move by first
adding additional logic to various Kconfig files to select this when
required and then use the moveconfig tool. In many cases we can select
these because they are required to implement other drivers. We also
correct how we include the various hashing algorithms in SPL.
This commit was generated as follows (after Kconfig additions):
[1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL
[2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL
Note:
We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously
because there is dependency between them.
