Adds support for ethernet networking on the da830evm platform.
This platform uses an SoC EMAC interface and a 3 port ethernet
switch as a PHY with an RMII interface. The PHY also has a i2c
interface for configuring the switch functions.

Davinci: Table driven pinmux configuration
Add code to allow pinmux_config tables to be grouped and configured
as a single resource. This removes multiple calls to the pinmux
configuration code from board_init and allows pinmuxes to be
individually configured and added by data manipulation only.
All related #ifdefs can the be removed from board_init code and
since the compiler optimises away statics, #ifdefs can be reduced in
the data definitions as well.

We get a compliation warning when we enable the NAND driver

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...)

Initial U-Boot support for the DaVinci DM355 EVM. This is a board
from Spectrum Digital. Board docs include schematic and firmware
for its microcontroller:
http://c6000.spectrumdigital.com/evmdm355/revd/
Most of the DM355 chip is fully documented by TI, the most notable
exception being the MPEG/JPEG coprocessor (programmable using codecs
available at no cost from TI), which is omitted from its DM335 sibling:
http://focus.ti.com/docs/prod/folders/print/tms320dm355.html
This version can boot from the on-board DM9000 Ethernet chip, after
being loaded (from NAND, MMC/SD, or UART). In the near future, NAND
and USB support could be added ... NAND support is being held back
until the support for the 4-bit ECC hardware is ready.

actually the timer init use the interrupt_init as init callback
which make the interrupt and timer implementation difficult to follow
so now rename it as int timer_init(void) and use interrupt_init for interrupt
btw also remane the corresponding file to the functionnality implemented
as ixp arch implement two timer - one based on interrupt - so all the timer

Chips without the EMAC controller won't need the utilities
it uses to read an Ethernet address from EEPROM; so don't
include them needlessly.
Use is_valid_ether() to validate the address from EEPROM.
All-zero addresses aren't the only invalid addresses.
A fully erased EEPROM returns all-ones, also invalid...
Switch those Ethernet utilities to use "%pM" for printing
MAC addresses; and not say ROM when they mean EEPROM.

A recent gcc added a new unaligned rodata section called '.rodata.str1.1',
which needs to be added the the linker script. Instead of just adding this
one section, we use a wildcard ".rodata*" to get all rodata linker section
gcc has now and might add in the future.
However, '*(.rodata*)' by itself will result in sub-optimal section
ordering. The sections will be sorted by object file, which causes extra
padding between the unaligned rodata.str.1.1 of one object file and the
aligned rodata of the next object file. This is easy to fix by using the
SORT_BY_ALIGNMENT command.
This patch has not be tested one most of the boards modified. Some boards
have a linker script that looks something like this:
*(.text)
. = ALIGN(16);
*(.rodata)
*(.rodata.str1.4)
*(.eh_frame)
I change this to:
*(.text)
. = ALIGN(16);
*(.eh_frame)
*(SORT_BY_ALIGNMENT(SORT_BY_NAME(.rodata*)))
This means the start of rodata will no longer be 16 bytes aligned.
However, the boundary between text and rodata/eh_frame is still aligned to
16 bytes, which is what I think the real purpose of the ALIGN call is.

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]
For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.
The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.
