Now that no driver any longer depends on the CONFIG_SOC_AU1??? symbols,
it's time to get rid of them: Move some of the platform devices to the
boards which can use them, Rename a few (unused) constants in the header,
Replace them with MIPS_ALCHEMY in the various Kconfig files. Finally
delete them altogether from the Alchemy Kconfig file.

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.
This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).
Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

The current Kconfig text for CONFIG_IDE doesn't give a hint to users that this
subsystem is currently in maintenance mode and isn't actively developed.
Let's correct this by marking it as deprecated, and also get rid of a bunch of
unnecessary text that doesn't really have anything to do with what the option is
for.

This is IDE host driver for AT91 (SAM9, CAP9, AT572D940HF) Static Memory
Controller with Compact Flash True IDE Mode logic.
Driver have to switch 8/16 bit bus width when accessing Task Tile or Data
Register. Moreover some extra things need to be done when setting PIO mode.
Only PIO mode is used, hardware have no DMA support. If interrupt line is
connected through GPIO extra quirk is needed to cope with fake interrupts.

- Added a comment to each of the sscanf lines.

This is a port of libata's pata_cs5536.c (written by Martin K. Petersen)
to IDE subsystem.
Changes done while at it:
* Reprogram PIO/MWDMA timings if needed before and after DMA transfer
(chipset uses shared PIO/MWDMA timings).
* Fix cable detection to report 80-wires cable if BIOS set it for any
device on a port (IDE core will do drive-side cable detection later).
* Don't disable UDMA while programming PIO timings.
* Simplify PCI/MSR support.
Pros of having IDE host driver in addition to libata's one:
* IDE is much lighter than SCSI+libata, the host driver itself is also
a bit smaller:
text data bss dec hex filename
1261 496 4 1761 6e1 drivers/ata/pata_cs5536.o
1242 128 4 1374 55e drivers/ide/cs5536.o
* This allows use of IDE features which are unavailable under libata.
v2:
* Fixes per review from Sergei:
- simplify dependency check in Kconfig
- use IDE_DRV_MASK also for ->drive_data
- disable UDMA when programming MWDMA
- program new DTC timings only when necessary
- fix printk() level in cs5536_init_one()
* Fix patch description according to comments from Alan and Sergei.
v3:
* Smarter masking of UDMA bits per Sergei's suggestion.

Support for the IT8172 IDE controller was removed from the kernel
sometime after 2.6.18. Support for the only boards that used the IT8172
was removed from the kernel after 2.6.18, as they had never compiled
since 2.6.0. However, there are a couple of platforms that use this
chip: the PMC-Sierra Xiao Hu thin-client computer, which is no longer
in production, and the Linksys NSS4000 Network Attached Storage box,
which is based on the Xiao Hu board. I am attempting to add support
for the Xiao Hu to the kernel, and this IT8172 IDE controller is the
first bit of code in this effort.
This patch resurrects the IT8172 IDE controller code. I began with
the 2.6.18 version of the it8172.c file, and have moved it forward so
that it works with the latest version of the kernel. I have run this
driver on a PMC-Sierra Xiao Hu board with the 2.6.28 kernel, and
I have had no problems with it in my configuration. The attached patch
applies cleanly against 2.6.28.
