- Add magic for booting NAND flash.
- Change CONFIG_ETRAXFS_SIM to CONFIG_ETRAX_VCS_SIM.

- Use (EtraxFS or Artpec-3) machine specific include for dram and hardware init.
- Remove old specific targets, use more generic ones instead.
- Use if_changed to avoid creating new images when no change.
- Use EXTRA_CFLAGS instead of CFLAGS.
- Remove old specific targets, use more generic ones instead.
- Use if_changed to avoid creating new images when no change.
- Use KBUILD_CFLAGS instead of CFLAGS.
- Use default partition table when no partition is found (for initial tests)
- Add config ETRAX_AXISFLASHMAP_MTD0WHOLE to allow whole flash as mtd0.

- Add config item to set I2C data and clock port.
- Put unneeded testcode inside #if 0.
- Remove CVS id tag.
- Remove CRISv32 common arbiter, dma, io and pinmux files,
they are now defined in machine dependent directories.
- Add cache and cacheflush files for working around cache problems
in CRISv32 chips.
The two chips are somewhat different, and needs different handling.
Adds handing of the dma, dram initialization, hardware settings, io,
memory arbiter and pinmux
Also moves the dma, dram initialization and io from CRIS v32 common files.
- Remove some unneeded configs and add some new ones.
- Merge common config items to common file instead of duplicating them.
- Pull in standard Kconfig.preempt.
- Remove some unneeded Kconfigs for subsystems not (yet) available on CRIS
(md, scsi, ieee1394, i2o, isdn, telephony, media, pcmcia, pci)
- Rename CRISv32 config items which had different types from CRISv10.
(ETRAX_LED2G, ETRAX_LED2R, ETRAX_LED3G, ETRAX_LED3R, ETRAX_I2C_DATA_PORT,
ETRAX_I2C_CLK_PORT)
An extra error handling label is needed for the case where the ioremap has
succeeded.

Improve including of architecture dependent Kconfig files.
- Always include the architecture dependent Kconfig files.
- Wrap architecture dependent Kconfig files inside an appropriate
"if ETRAX_ARCH_Vxx" block.
This makes it possible to run the configuration even without the arch links,
which are created later in the build process.

This code is really really really broken. So much so that it's almost
impossible to fix with a simple patch, so just comment out the offending
registration with the kobject core, and mark the driver as broken.
The problem is that the code is trying to register a "raw" struct
device, which is not allowed. struct device is only for use within the
driver model. This is being done to try to use the firmware layer which
wants a struct device. To properly fix this, use something easy, like a
platform device, which is a struct device and can be used for this kind
of thing.

* Move ETRAX_IDE and friends from arch/cris/arch-{v10,v32}/drivers/Kconfig
to drivers/ide/Kconfig.
* Don't force selecting ide-disk and ide-cd device drivers
(please handle this through defconfig if necessary).
* Make ETRAX_IDE depend on BROKEN for the time being
(it doesn't even compile currently).

These are needed due to a cache bug, and can be used to make sure that the
DMA descriptors are flushed to memory and can be safely handled by DMA.
flush_dma_descr - Flush one DMA descriptor.
flush_dma_list - Flush a complete list of DMA descriptors.
cris_flush_cache - Flush the complete cache.
cris_flush_cache_range - Flush only the specified range

Remove MTD_AMDSTD and MTD_OBSOLETE_CHIPS from defconfig, Kconfig and code,
