[POWERPC] Pass per-file CFLAGs for platform specific op codes
As a result of compiling all of the wrapper files for every platform

[POWERPC] Small fixes for the Ebony device tree
This patch corrects a number of minor errors in the Ebony device tree:
- Missing (given as 0) cache sizes are added to the CPU node
- device_type properties are removed from nodes which don't
have a reasonably well defined device_type binding. This does require
a very small code change to locate the busses to be probed for
of_platform devices by 'compatible' instead of 'device_type'.
- A node is added for the SRAM controller
- The unit address of the small-flash node is adjusted to
correctly reflect the reg property.
- device_type values for the MAL and ZMII are updated to
reflected more up-to-date versions of the binding.
- An incorrect offset in the partition map for the large-flash
node is corrected.
- Some redundant values, already commented out are removed
entirely.

However, when adding properties, it adds the property definition

Fix ACPI suspend / device suspend ordering problem
In commit
e3c7db621bed4afb8e231cb005057f2feb5db557 we fixed the resume
ordering, so that the ACPI low-level resume code was called before the
actual driver resume was called. However, that broke the nesting logic
of suspend and resume, and we continued to suspend the devices _after_
we the ACPI device suspend code was called.
That resulted in us saving PCI state for devices that had already been
changed by ACPI, and in some cases disabled entirely (causing the PCI
save_state to be all-ones). Which in turn caused the wrong state to be
written back on resume.
This moves the ACPI device suspend to after the device model per-device
suspend() calls. This fixes the bogus state save.

o Only register/deregister this custom codec device with the AC97 bus.
The generic AC97 driver already does this for generic codec devices.

libata: during revalidation, check n_sectors after device is configured
Device might be resized during ata_dev_configure() due to HPA or
(later) ACPI _GTF. Currently it's worked around by caching n_sectors
before turning off HPA. The cached original size is overwritten if
the device is reconfigured without being hardreset - which always
happens after configuring trasnfer mode. If the device gets hardreset
for some reason after that, revalidation fails with -ENODEV.
This patch makes size checking more robust by moving n_sectors check
from ata_dev_reread_id() to ata_dev_revalidate() after the device is
fully configured. No matter what happens during configuration, a
device must have the same n_sectors after fully configured to be
treated as the same device.

[SPARC64]: Add hypervisor API negotiation and fix console bugs.
Hypervisor interfaces need to be negotiated in order to use
some API calls reliably. So add a small set of interfaces
to request API versions and query current settings.
This allows us to fix some bugs in the hypervisor console:
1) If we can negotiate API group CORE of at least major 1
minor 1 we can use con_read and con_write which can improve
console performance quite a bit.
2) When we do a console write request, we should hold the
spinlock around the whole request, not a byte at a time.
What would happen is that it's easy for output from
different cpus to get mixed with each other.
3) Use consistent udelay() based polling, udelay(1) each
loop with a limit of 1000 polls to handle stuck hypervisor
console.

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

ucc_geth: eliminate max-speed, change interface-type to phy-connection-type
It was agreed that phy-connection-type was a better name for
the interface-type property, so this patch renames it.
Also, the max-speed property name was determined too generic,
and is therefore eliminated in favour of phy-connection-type
derivation logic.

smc911x: fix compilation breakage
Looks like the new version of this patch has been overlooked,
so I'm resending it.
It just adapts the driver to the new IRQ API
according to what Russell has pointed out.

pasemi_mac: Fix local-mac-address parsing
Turns out we have an old version of firmware that stores the mac address
in 'mac-address' as a string instead of a byte array. All versions that
use local-mac-address should have it as byte array, so no need to do
string parsing for that case.
