This patch adds 4 BIT ECC support in the DaVinci NAND
driver. Tested on both the DM355 and DM365.

Update chipselect handling in davinci_nand.c so that it can
handle 2 GByte chips the same way Linux does: as one device,
even though it has two halves with independent chip selects.
For such chips the "nand info" command reports:
Device 0: 2x nand0, sector size 128 KiB
Switch to use the default chipselect function unless the board
really needs its own. The logic for the Sonata board moves out
of the driver into board-specific code. (Which doesn't affect
current build breakage if its NAND support is enabled...)

All DaVinci SOC's use a CLE mask of 0x10 and an ALE mask of 0x8
except the DM646x. This was decided by the design team driving the design.
This patch updates the CLE and ALE values for DM646x.
Updated patches for DM646x will be sent shortly.
This applies to u-boot-nand-flash git

The ALE mask used by DaVinci SOCs is wrong. The patch changes the mask value
from '0xa' to '0x8'. This is the mask we use for all TI releases.

Remove CONFIG_SYS_DAVINCI_BROKEN_ECC option. It's not just nasty;
it's also unused by any current boards, and doesn't even match the
main U-Boot distributions from TI (which use soft ECC, or 4-bit ECC
on newer chips that support it).
DaVinci GIT kernels since 2.6.24, and mainline Linux since 2.6.30,
match non-BROKEN code paths for 1-bit HW ECC. The BROKEN code paths
do seem to partially match what MontaVista/TI kernels (4.0/2.6.10,
and 5.0/2.6.18) do ... but only for small pages. Large page support
is really broken (and it's unclear just what software it was trying
to match!), and the ECC layout was making three more bytes available
for use by filesystem (or whatever) code.
Since this option itself seems broken, remove it. Add a comment
about the MV/TI compat issue, and the most straightforward way to
address it (should someone really need to solve it).

Minor cleanup for DaVinci NAND code:
- Use I/O addresses from nand_chip; CONFIG_SYS_NAND_BASE won't
be defined when there are multiple chipselect lines in use
(as with common 2 GByte chips).
- Cleanup handling of EMIF control registers
* Only need one pointer pointing to them
* Remove incorrect and unused struct supersetting them
- Use the standard waitfunc; we don't need a custom version
- Partial legacy cleanup:
* Don't initialize every board like it's a DM6446 EVM
* #ifdef a bit more code for BROKEN_ECC
Sanity checked with small page NAND on dm355 and dm6446 EVMs;
and large page on dm355 EVM (packaged as two devices, not one).

Different flavours of DaVinci SOC's have differences in their EMAC IP
This patch does the following
1) Updates base addresses for DM365
2) Updates MDIO frequencies for DM365 and DM646x
3) Update EMAC wrapper registers for DM365 and DM646x
Patch applies to u-boot-net git. the EMAC driver itself
will be updated shortly to add support for DM365 and DM646x

Move the clock-rate dumping code into the cpu/.../davinci area
where it should have been, enabled by CONFIG_DISPLAY_CPUINFO,
updating the format and showing the DSP clock (where relevant).
Switch boards to use the cpuinfo() hook for this stuff.
Remove a few now-obsolete PLL #defines.

Add some basic declarations for DaVinci DM355/DM350/DM335 support,
keyed on CONFIG_SOC_DM355. (DM35X isn't quite right because the
DM357 is very different; while the DM355 is like a DM355 without
the MPEG/JPEG coprocessor).
These have different peripherals than the DM6446, and some of
the peripherals are at different addresses. Notably for U-Boot,
there's no EMAC, and the NAND controller address is different

Move DaVinci PSC support from board/* to cpu/* where it belongs.
The PSC module manages clocks and resets for all DaVinci-family
SoCs, and isn't at all board-specific.

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...
