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/fec.h

- 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.

a6ab4bf978 Patches by Pantelis Antoniou, 30 Mar 2004:
Improve and fix various things in the MPC8xx FEC driver:
1. The new 87x and 88x series of processors have two FECs,
   and the new driver supports them both.
2. Another change in the 87x/88x series is support for
   the RMII (Reduced MII) interface. However numerous
   changes are needed to make it work since the PHYs
   are connected to the same lines. That means that
   you have to address them correctly over the MII
   interface.

  MPC860FADS fixes:
  - add MPC86xADS support (uses MPC86xADS.h)
  - add 866P/T core support (also MPC859T/MPC859DSL/MPC852T)
    o PLPRCR changes
    o BRG changes (EXTAL/XTAL restricted to 10MHz)
    o don't trust gclk() software measurement by default, depend on
      CONFIG_8xx_GCLK_FREQ
  - add DRAM SIMM not installed detection
  - use more "correct" SDRAM initialization sequence
  - allow different SDRAM sizes (8xxADS has 8M)
  - default DER is 0
  - remove unused MAMR defines from FADS860T.h (all done in fads.c)
  - rename MAMR/MBMR defines to be more consistent. Should eventually
    be merged into MxMR to better reflect the PowerQUICC datasheet.
