- According to ARM Dual-Timer Module (SP804) TRM (ARM DDI0271),
   -- Timer Value Register @ TIMER Base + 4 is Read-only.
   -- Prescale Value (Bits 3-2 of TIMER Control register)
	can only be one of 00,01,10. 11 is undefined.
   -- CFG_HZ for Versatile board is set to
	#define CFG_HZ		(1000000 / 256)
	So Prescale bits is set to indicate
	- 8 Stages of Prescale, Clock divided by 256
 - The Timer Control Register has one Undefined/Shouldn't Use Bit
   So we should do read/modify/write Operation

Here comes a trivial patch to cpu/arm926ejs/davinci/nand.c. Unfortunately I
don't have hardware handy so I can not test it at the moment but changes are
rather trivial so it should work. It would be nice if somebody with a
hardware checked it anyways.

A lot changed in the Linux MTD code, since it was last ported from
Linux to U-Boot. This patch takes U-Boot NAND support to the level
of Linux 2.6.22.1 and will enable support for very large NAND devices
(4KB pages) and ease the compatibility between U-Boot and Linux
filesystems.

This patch is tested on two custom boards with PPC and ARM
processors running YAFFS in U-Boot and Linux using gcc-4.1.2
cross compilers.

MAKEALL ppc/arm has some issues:
 * DOC/OneNand/nand_spl is not building (I have not tried porting
   these parts, and since I do not have any HW and I am not familiar
   with this code/HW I think its best left to someone else.)

Except for the issues mentioned above, I have ported all drivers
necessary to run MAKEALL ppc/arm without errors and warnings. Many
drivers were trivial to port, but some were not so trivial. The
following drivers must be examined carefully and maybe rewritten to
some degree:
 cpu/ppc4xx/ndfc.c
 cpu/arm926ejs/davinci/nand.c
 board/delta/nand.c
 board/zylonite/nand.c

Fix ARM based DaVinci DM644x timer overflow handling and cleanup timer code.

Changes:

- Remove *_masked() functions as noted by Wolfgang

- Adapt register naming to recent TI spec (sprue26, March 2007)

- Fix reset_timer() handling

- As reported by Pieter [1] the overflow fix introduced a delay of factor 16 (e.g 2 seconds became 32). While the overflow fix is basically okay, it missed to divide udelay by 16, too. Fix this.

[1] http://article.gmane.org/gmane.comp.boot-loaders.u-boot/38179

- Remove software division of timer count value (DIV(x) macro) and do it in hardware (TIM_CLK_DIV).

Many thanks to Troy Kisky <troy.kisky@boundarydevices.com> and Pieter Voorthuijsen <pieter.voorthuijsen@Prodrive.nl> for the hints & testing!

Add support for the following DaVinci boards:
- DV_EVM
- SCHMOOGIE
- SONATA

Changes:

- Split into separate board directories
- Removed changes to MTD_DEBUG (or whatever it's called)
- New CONFIG_CMD party line followed
- Some cosmetic fixes, cleanup etc.
- Patches against the latest U-Boot tree as of now.
- Fixed CONFIG_CMD_NET in net files.
- Fixed CONFIG_CMD_EEPROM for schmoogie.
- Made sure it compiles and works (forceenv() link problem) on SCHMOOGIE and
   DV_EVM. Can't check if it works on SONATA, don't have a board any more,
   but it at least compiles.

Here is an excerpt from session log on SCHMOOGIE...

Based on patch by Mike Frysinger, 20 Jun 2006

Modifications are based on the linux kernel approach and
support two use cases:

  1) Add O= to the make command line
  'make O=/tmp/build all'

  2) Set environement variable BUILD_DIR to point to the desired location
  'export BUILD_DIR=/tmp/build'
  'make'

The second approach can also be used with a MAKEALL script
'export BUILD_DIR=/tmp/build'
'./MAKEALL'

Command line 'O=' setting overrides BUILD_DIR environent variable.

When none of the above methods is used the local build is performed and
the object files are placed in the source directory.

  - Fix OMAP support that omap5912osk compiles in current source tree
  - Update with code from "http://omap.spectrumdigital.com/osk5912"
    to fix problems with DDR initialization
  - Fix timer setup
  - Use CFI flash driver and support complete 32MB of onboard flash
  - Add "print_cpuinfo()" and "checkboard()" functions to display
    CPU (with frequency) and Board infos
