This patch fixes 2 problems with FDT EBC mappings on Canyonlands.
First, NAND EBC mapping was missing, making Linux NAND driver
unusable on this board. Second, NOR remapping code assumed that
NOR is always on CS0, however when booting from NAND NOR is on CS3.

Currently, when booting from NAND using nand_spl, in the beginning the default
environment is used until later in boot process the dynamic environment is read
out. This way environment variables that must be interpreted early, like the
baudrate or "silent", cannot be modified dynamically and remain at their
default values. Fix this problem by reading out main and redundand (if used)
copies of the environment in the nand_spl code.

The BF537-STAMP Blackfin board had a driver for working with NAND devices
that are simply memory mapped. Since there is nothing Blackfin specific
about this, generalize the driver a bit so that everyone can leverage it.

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

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).

This sets CONFIG_SYS_HZ to 1000 as required, and completely rewrites
timer code, which is now both correct and much smaller. Unused
functions like udelay_masked() have been removed as no driver uses
them, even the ones that are not currently active for this board.
mtu.h is copied literally from the kernel sources.
