[PATCH v2 01/10] powerpc/8xx: move CPM1 related files from sysdev/ to platforms/8xx

[PATCH v2 01/10] powerpc/8xx: move CPM1 related files from sysdev/ to platforms/8xx

[Christophe Leroy]

Only 8xx selects CPM1 and related CONFIG options are already
in platforms/8xx/Kconfig

Move the related C files to platforms/8xx/.

[PATCH v2 05/10] powerpc/8xx: Refactor microcode write

[Christophe Leroy]

Add empty microcode tables so that all tables are defined
all the time. Regroup the writing of the 3 tables regardless
of the selected microcode.

define them as part of the patch set and refactor their
programming from that definition.

[PATCH v2 10/10] powerpc/8xx: Add microcode patch to move SMC parameter RAM.

[Christophe Leroy]

Some SCC functions like the QMC requires an extended parameter RAM.
On modern 8xx (ie 866 and 885), SPI area can already be relocated,
allowing the use of those functions on SCC2. But SCC3 and SCC4
parameter RAM collide with SMC1 and SMC2 parameter RAMs.

This patch adds microcode to allow the relocation of both SMC1 and
SMC2, and relocate them at offsets 0x1ec0 and 0x1fc0.
Those offsets are by default for the CPM1 DSP1 and DSP2, but there
is no kernel driver using them at the moment so this area can be
reused.

This microcode is provided by Freescale/NXP in Engineering Bulletin
EB662 ("MPC8xx I2C/SPI and SMC Relocation Microcode Packages")
dated 2006. The binary code is public. The source is not available.
