serverworks: PIO mode setup fixes
* limit max PIO mode to PIO4, this driver doesn't support PIO5 and attempt
to program PIO5 by svwks_tune_chipset() could result in incorrect PIO
timings being programmed and possibly the data corruption (it seems that
the minimum possible values were used but I lack the datasheets to be sure)
* select best PIO mode in svwks_tune_drive() and not in svwks_tune_chipset()
when doing PIO autotuning (pio == 255)
* don't try to tune PIO in config_chipset_for_dma() as ide_dma_enable() could
return 1 if DMA was previously enabled (svwks_config_drive_xfer_rate()
takes care of PIO tuning if no suitable DMA mode is found)
* remove config_chipset_for_pio() and use svwks_tune_drive() instead,
config_chipset_for_pio() contained numerous bugs when selecting PIO mode
(luckily it was only used for devices limited to PIO by capabilities/BIOS):
- it didn't check for validity of id->eide_pio_modes and id->eide_pio_iordy
before using them
- it tried to found out maximum PIO mode basing on minimum IORDY cycle time
(moreover wrong cycle times were used for PIO0/1/5)
- it was overriding PIO blacklist and conservative PIO "downgrade" done
by ide_get_best_pio_mode()
- if the max drive PIO was PIO5 then XFER_PIO_0/XFER_PIO_SLOW was selected
(XFER_PIO_SLOW is not supported by svwks_tune_chipset() so the result
was the same as if using XFER_PIO_5 => wrong PIO timings were set)
- it was overriding drive->current_speed
* bump driver version

pdc202xx_old: rewrite mode programming code (v2)
This patch is based on the documentation (I would like to thank Promise
for it) and also partially on the older vendor driver.
Rewrite mode programming code:
* disable 66MHz clock in pdc202xx_tune_chipset() so it is correctly disabled
even if both devices on the channel are not DMA capable and after reset
* enable/disable IORDY and PREFETCH bits in pdc202xx_tune_chipset()
as they need to be setup correctly also for PIO only devices, plus IORDY
wasn't disabled for non-IORDY devices and PREFETCH wasn't disabled for
ATAPI devices
* remove dead code for setting SYNC_ERDDY_EN bits from config_chipset_for_dma()
(driver sets ->autotune to 1 so PIO modes are always programmed => lower
nibble of register A never equals 4 => "chipset_is_set" is always true)
* enable PIO mode programming for all ATAPI devices
(it was limited to ->media == ide_cdrom devices)
* remove extra reads of registers A/B/C, don't read register D et all
* do clearing / programming of registers A/B/C in one go
(gets rid of extra PCI config space read/write cycle)
* set initial values of drive_conf/AP/BP/CP variables to zero
(paranoia for the case when PCI reads fail)
* remove XFER_UDMA6 to XFER_UDMA5 remapping case - it can't happen
(ide_rate_filter() takes care of it)
* fix XFER_MW_DMA0 timings (they were overclocked, use the official ones)
* fix bitmasks for clearing bits of register B:
- when programming DMA mode bit 0x10 of register B was cleared which
resulted in overclocked PIO timing setting (iff PIO0 was used)
- when programming PIO mode bits 0x18 weren't cleared so suboptimal
timings were used for PIO1-4 if PIO0 was previously set (bit 0x10)
and for PIO0/3/4 if PIO1/2 was previously set (bit 0x08)
* add FIXME comment about missing locking for 66MHz clock register
Also while at it:
* remove unused defines
* do a few cosmetic / CodingStyle fixes
* bump driver version
v2:
* in pdc202xx_tune_chipset() the old content of drive configuration
registers is used only by the debugging code so cover "drive_conf"
PCI registers read by #if PDC202XX_DEBUG_DRIVE_INFO

policy count for that direction. Since the user can supply any value
for dir, this can corrupt our policy count.
I know this is the problem because a few days ago I was deleting
policies by hand using indicies and accidentally typed in the wrong
direction. It still deleted the policy and at the time I thought
that was cool. In retrospect it isn't such a good idea :)

[POWERPC] Add arch/powerpc support for the Motorola PrPMC2800
This finally adds the PPC_PRPMC2800 Kconfig option, the board setup
code (the setup and reset functions) and the defconfig, to support the
Motorola PrPMC2800 platform.

[POWERPC] Add bootwrapper support for Motorola PrPMC2800 platform
The Motorola PrPMC280 and PrPMC2800 processor modules sit on an F101 or
PrPMC2800 baseboard, respectively. There are several variants of each
type of processor module which can have different amounts of memory,
amounts of FLASH, cpu frequencies, and an mv64360 or an mv64362.
The bootwrapper code for that platform reads VPD from an I2C EEPROM
to determine the processor module variant. From the variant, the
amount of memory, etc. is determined and the device tree is updated
accordingly. If the variant cannot be determined (e.g., corrupted
VPD or a previously unknown variant), the property values already
in the device tree are used.
Also, the firmware for those platforms does not completely configure
the mv64x60 host bridge so that configuration is done here.

[POWERPC] Add DTS file for the Motorola PrPMC2800 platform
Add the device tree source file for the prpmc2800 line of processor PMCs.
Several of the property values are updated by the bootwrapper but sane
defaults have been chosen in case the bootwrapper can't determine the
exact processor board variant. The defaults should allow the kernel
to boot despite having non-optimal device tree property values.

check_cache_coherency() verifies that the cache coherency setting of
the kernel (CONFIG_NOT_COHERENT_CACHE) matches that left by the firmware,

This patch adds PCI bridge support for the Marvell mv64x60 chip.
We also provide the ability to read/write the mv64x60 hotswap

device tree.
