DM644x is just one of a series of DaVinci chips that use the EMAC driver.
By replacing all the function names that start with dm644x_* to davinci_*
we make these function more portable. I have tested this change on my EVM.
DM6467 is another DaVinci SOC which uses the EMAC driver and i will
be sending patches that add DaVinci DM6467 support to the list soon.

- 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

This is particularly problematic now that non-NAND-specific code is
including <nand.h>, and thus all debugging code is being compiled
regardless of whether it was requested, as reported by Scott McNutt

This commit gets rid of a huge amount of silly white-space issues.
Especially, all sequences of SPACEs followed by TAB characters get
removed (unless they appear in print statements).
Also remove all embedded "vim:" and "vi:" statements which hide
indentation problems.

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!

AT91CAP9 and AT91SAM9 SoCs are very close hardware wise, so a

The timer on AT91CAP9/AT91SAM9 is supplied by the SoC, and not by

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...

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
