    14

    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

    - arch/powerpc/cpu/mpc8xx/upatch.c

    - drivers/video/mpc8xx_lcd.c
    - examples/standalone/test_burst.c
    - examples/standalone/test_burst.h
    - examples/standalone/test_burst_lib.S
    - examples/standalone/timer.c
    - include/mpc823_lcd.h
    - include/usb/mpc8xx_udc.h
    - post/cpu/mpc8xx/Makefile
    - post/cpu/mpc8xx/cache.c
    - post/cpu/mpc8xx/cache_8xx.S
    - post/cpu/mpc8xx/ether.c
    - post/cpu/mpc8xx/spr.c
    - 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.

    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.
