Newer PPC's like 440SPe, 460EX/GT can be equipped with more than 2GB of SDRAM.
To support such configurations, we "only" map the first 2GB via the TLB's. We
need some free virtual address space for the remaining peripherals like, SoC
devices, FLASH etc.
Note that ECC is currently not supported on configurations with more than 2GB
SDRAM. This is because we only map the first 2GB on such systems, and therefore
the ECC parity byte of the remaining area can't be written.

This patch (Part 1 of 2):
* Rolls up a suite of changes to enable correct primordial stack and
global data handling when the data cache is used for such a purpose
for PPC40x-variants (i.e. CFG_INIT_DCACHE_CS).
* Related to the first, unifies DDR2 SDRAM and ECC initialization by
eliminating redundant ECC initialization implementations and moving
redundant SDRAM initialization out of board code into shared 4xx
code.
* Enables MCSR visibility on the 405EX(r).
* Enables the use of the data cache for initial RAM on
both AMCC's Kilauea and Makalu and removes a redundant
CFG_POST_MEMORY flag from each board's CONFIG_POST value.
- Removed, per Stefan Roese's request, defunct memory.c file for
Makalu and rolled sdram_init from it into makalu.c.
With respect to the 4xx DDR initialization and ECC unification, there
is certainly more work that can and should be done (file renaming,
etc.). However, that can be handled at a later date on a second or
third pass. As it stands, this patch moves things forward in an
incremental yet positive way for those platforms that utilize this

This patch makes two additions to GPIO support:
First, it adds function gpio_read_in_bit() to read the a bit from the
GPIO Input Register (GPIOx_IR) in the same way that function
gpio_read_out_bit() reads a bit from the GPIO Output Register
(GPIOx_OR).
Second, it modifies function gpio_set_chip_configuration() to provide
an additional option for configuring the GPIO from the
"CFG_4xx_GPIO_TABLE".
According to the 440EPx User's Manual, when an alternate output is used,
the three-state control is configured in one of two ways, depending on
the particular output. The first option is to select the corresponding
alternate three-state control in the GPIOx_TRSH/L registers. The second
option is to select the GPIO Three-State Control Register (GPIOx_TCR) in
the GPIOx_TRSH/L registers, and set the corresponding bit in the
GPIOx_TCR register to enable the output. For example, the Manual
specifies configuring the GPIO00 Alternate 1 Signal (PreAddr07) to use
the alternate three-state control (first option), and specifies
configuring the GPIO32 Alternate 1 Signal (USB2OM0) with the output
enabled in the GPIOx_TCR register (second option).
Currently, gpio_set_chip_configuration() configures all alternate signal
outputs to use the first option. This patch allow the second option to
be selected by setting the "out_val" element in the table entry to
"GPIO_OUT_1". The first option is used when the "out_val" element is
set to "GPIO_OUT_0". Because "out_val" is not currently used when an
alternate signal is selected, and because all current GPIO tables set
"out_val" to "GPIO_OUT_0" for all alternate signals, this patch should
not change any existing configurations.

map_physmem() returns a virtual address which can be used to access a

This patch adds a stub implementation which simply returns the

which converts the physical address to an uncached virtual mapping.
unmap_physmem() is a no-op on all architectures, but if any
architecture needs to do such mappings through the TLB, this is the
hook where those TLB entries can be invalidated.

Support external interrupts from platform to eliminate system hangs.
Define CONFIG_INTERRUPTS board configure option to enable.
Enable ecm, ddr, lbc, and pci/pcie error interrupts in PIC.
Remove extra cpu initialization redundant with hardware initialization.
Whitespace cleanup.
Define and use _START_OFFSET consistent with other processors using
ppc_asm.tmpl
Move additional code from .text to boot page to make room for
exception vectors at start of image.
Handle Machine Check, External and Critical exceptions.
Fix e500 machine check error determination in traps.c
TEXT_BASE can now be 0xfffc_0000 - which cuts binary image in half.

All of the PCI/PCI-Express driver and initialization code that
was in the MPC8641HPCN port has now been moved into the common
drivers/fsl_pci_init.c. In a subsequent patch, this will be
utilized by the 85xx ports as well.
Common PCI-E IMMAP register blocks for FSL 85xx/86xx are added.
Also enable the second PCI-Express controller on 8641
by getting its BATS and CFG_ setup right.
Fixed a u16 vendor compiler warning in AHCI driver too.

The new function remove_tlb() can be used to remove the TLB's used to
map a specific memory region. This is especially useful for the DDR(2)
setup routines which configure the SDRAM area temporarily as a cached
area (for speedup on auto-calibration and ECC generation) and later
need this area uncached for normal usage.

- Introduced dedicated switches for building 440 and 405 images required
for 440-specific machine instructions like 'rfmci' etc.
- Exception vectors moved to the proper location (_start moved away from
the critical exception handler space, which it occupied)
- CriticalInput now serviced (with default handler)
- MachineCheck properly serviced (added a dedicated handler and return
subroutine)
- Overall cleanup of exceptions declared with STD_EXCEPTION macro (unused,
unhandled and those not relevant for 4xx were eliminated)
- Eliminated Linux leftovers, removed dead code

Rather than misleadingly define PVR_83xx as the specific type of 83xx
being built for, the PVR of each core revision is defined. checkcpu() now
prints the core that it detects, rather than aborting if it doesn't find
what it thinks it wants.

For better format and style, I streamlined the 83xx head files,
including immap_83xx.h and mpc83xx.h. In the old head files, 1)
duplicated macro definition appear in the both files; 2) the structure
of QE immr is duplicated in the immap_83xx.h and immap_qe.h; 3) The
macro definition put inside the each structure. So, I cleaned up the
structure of QE immr from immap_83xx.h, deleted the duplicated stuff and
moved the macro definition to mpc83xx.h, Just like MPC8260.

Some CPUs like PPC, BLACKFIN need sync() to ensure cfi flash write command

This patch adds support for the DDR2 controller used on the
440SP and 440SPe. It is tested on the Katmai (440SPe) eval
board and works fine with the following DIMM modules:
- Corsair CM2X512-5400C4 (512MByte per DIMM)
- Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM)
- Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM)
This patch also adds the nice functionality to dynamically
create the TLB entries for the SDRAM (tlb.c). So we should
never run into such problems with wrong (too short) TLB
initialization again on these platforms.

1. Add 7447A and 7448 processor support.
2. Add the following flags.
CFG_CONFIG_BUS_CLK : If the 74xx bus frequency can be configured dynamically
(such as by switch on board), this flag should be set.
CFG_EXCEPTION_AFTER_RELOCATE: If an exception occurs after the u-boot
relocates to RAM, this flag should be set.
CFG_SERIAL_HANG_IN_EXCEPTION: If the print out function will cause the
system hang in exception, this flag should be set.
