This updates the optional (non-default!) NAND support for the
DaVinci DM6446 EVM:

 - include MTD partitioning, defaulting to what Linux uses

 - use a flash-based BBT, which among other things speeds bootup

This matches code that's now queued for mainline Linux, and might
even merge in an upcoming 2.6.30-rc; and the MTIDS are set up so
that the U-Boot $mtdparts environment variable can be passed as-is
on the kernel command line as a cmdlinepart override.

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
related code is moved to timer.c

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

Split out DaVinci DM6446-specific bits from more generic bits:

 - Add a CONFIG_SOC_DM644X.  All current boards use DM6446 chips;
   DM6443 and DM6441 chips differ in available peripherals.

 - Move most DM644X-specific bits from psc.c to a new dm644x.c file,
   which is conditionally built.  It provides device-specific setup.

Plus minor coding style and comment updates with respect to the PSC.

Don't needlessly include lowlevel init code; that's only really

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.

This patch moves the malloc initialization before calling flash_init().
Upcoming changes to the NOR FLASH common CFI driver with optional
MTD infrastructure and MTD concatenation support will call malloc().
And nothing really speaks against enabling malloc just a little earlier
in the boot stage. Some architectures already enable malloc before
calling flash_init() so they don't need any changes here.

This patch adds another build target for the AMCC Sequoia PPC440EPx
eval board. This RAM-booting version is targeted for boards without
NOR FLASH (NAND booting) which need a possibility to initially
program their NAND FLASH. Using a JTAG debugger (e.g. BDI2000/3000)
configured to setup the SDRAM, this debugger can load this RAM-
booting image to the target address in SDRAM (in this case 0x1000000)
and start it there. Then U-Boot's standard NAND commands can be
used to program the NAND FLASH (e.g. "nand write ...").

Here the commands to load and start this image from the BDI2000:

440EPX>reset halt
440EPX>load 0x1000000 /tftpboot/sequoia/u-boot.bin
440EPX>go 0x1000000

Please note that this image automatically scans for an already
initialized SDRAM TLB (detected by EPN=0). This TLB will not be
cleared. This TLB doesn't need to be TLB #0, this RAM-booting
version will detect it and preserve it. So booting via BDI2000
will work and booting with a complete different TLB init via
U-Boot works as well.

New default, weak i2c_get_bus_speed() and i2c_set_bus_speed() functions
replace a number of architecture-specific implementations.

Also, providing default functions will allow all boards to enable
CONFIG_I2C_CMD_TREE.  This was previously not possible since the
tree-form of the i2c command provides the ability to display and modify
the i2c bus speed which requires i2c_[set|get]_bus_speed() to be
present.
