For some reason we duplicated the majority of code in lib_ppc/interrupts.c
not show how that happened, but there is no good reason for it.
Use the interrupt_init_cpu() and timer_interrupt_cpu() since its why
they exist.

The main purpose of this rewrite it to be able to share the same
initialization code on all FSL PowerPC products that have DDR
controllers. (83xx, 85xx, 86xx).
The code is broken up into the following steps:
GET_SPD
COMPUTE_DIMM_PARMS
COMPUTE_COMMON_PARMS
GATHER_OPTS
ASSIGN_ADDRESSES
COMPUTE_REGS
PROGRAM_REGS
This allows us to share more code an easily allow for board specific code
overrides.
Additionally this code base adds support for >4G of DDR and provides a
foundation for supporting interleaving on processors with more than one
controller.

This adds a helper function to unlock the PCI configuration bit, so that
any extra PCI setup (such as outbound windows, etc.) can be done after
using the 83XX_GENERIC_PCI code to set up the PCI bus.

- 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

During recent PCI-E tests it has been found that current
driverl level and de-emphasis values are not set correctly.
After sweeping throgh all de-ephasis values, it was found that
0x130 is a right value. Where 0x13 is driver level and 0 is
de-emphasis.

This patch fixes some minor issues introduced with the patch:
ppc4xx: Optimize PLB4 Arbiter... from Prodyut Hazarika:
- Rework memory-queue and PLB arbiter optimization code, that the
local variable is not needed anymore. This removes one #ifdef.
- Use consistant spacing in ppc4xx.h header (XXX + 0x01 instead
of XXX+ 0x01). This was not introduced by Prodyut, just a
copy-paste problem.

- Moved PLB4 Arbiter register definitions to ppc4xx.h since it is shared
across processors (405 and 440/460)
- Optimize Memory Queue settings for PPC440SP/SPE and PPC460EX/GT/SX
processors
- Add register bit definitions for Memory Queue Configuration registers

Move to using the environment variables 'ethaddr', 'eth1addr', etc..
instead of bd->bi_enetaddr, bi_enet1addr, etc.
This makes the code a bit more flexible to the number of ethernet
interfaces.

There is no point in disabling the icache on 7xx/74xx/86xx parts and not
also flushing the icache. All callers of invalidate_l1_instruction_cache()
call icache_disable() right after. Make it so icache_disable() calls
invalidate_l1_instruction_cache() for us.
Also, dcache_disable() already calls dcache_flush() so there is no point
in the explicit calls of dcache_flush().

Note that with older board revisions, NAND boot may only work after a
power-on reset, and not after a warm reset. I don't have a newer board
to test on; if you have a board with a 33MHz crystal, please let me know
if it works after a warm reset.

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.

This patch changes the 4xx NAND driver ndfc.c to match the new

subsystem was recently synced again with the Linux 2.6.22 MTD/NAND
subsystem.

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
