ppc4xx: Add Mnemonics for AMCC/IBM DDR2 SDRAM Controller
This patch completes the preprocessor mneomics for the IBM DDR2 SDRAM
controller registers (MODT and INITPLR) used by the
PowerPC405EX(r). The MMODE and MEMODE registers are unified with their
peer values used for the INITPLR MR and EMR registers,
respectively. Finally, a spelling typo is correct (MANUEL to MANUAL).
With these mnemonics in place, the CFG_SDRAM0_* magic numbers for
Kilauea are replaced by equivalent mnemonics to make it easier to
compare and contrast other 405EX(r)-based boards (e.g. during board
bring-up).
Finally, unified the SDRAM controller register dump routine such that
it can be used across all processor variants that utilize the IBM DDR2
SDRAM controller core. It produces output of the form:
PPC4xx IBM DDR2 Register Dump:
...
SDRAM_MB0CF[40] = 0x00006701
...
which is '<mnemonic>[<DCR #>] = <value>'. The DCR number is included
since it is not uncommon that the DCR values in header files get mixed
up and it helps to validate, at a glance, they match what is printed
in the user manual.

AMCC Kilauea/Haleakala:

This patch fixes a potentially serious issue related to USB which was
discouvered by Martin Krause <martin.krause@tqs.de> and fixed for
ARM920T. Martin wrote:
Turn off USB to prevent the host controller from writing to the
SDRAM while Linux is booting. This could happen, because the HCCA
(Host Controller Communication Area) lies within the SDRAM and the
host controller writes continously to this area (as busmaster!), for
example to increase the HccaFrameNumber variable, which happens
every 1 ms.
This is a slightly modified version of the patch in order to shutdown
USB when booting on all architectures.

ppc4xx: Enable support for > 2GB SDRAM on AMCC Katmai
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 makes SPARC targets build again. It is caused by
phys_addr_t and phys_size_t being defined in the wrong header

Fix boot from NOR due to incorrect reset delay.
AT91 RSTC registers are battery-backuped, so their values
are not reset across power cycles. One of those registers,
the AT91_RSTC_MR register, is being modified by U-Boot, in
the ethernet initialisation routine, to generate a 500ms
user reset.
Unfortunately, this value is not being restored afterwards,
causing subsequent resets to also last for 500ms.
This long reset sequence causes problems (at least) in the
boot sequence from NOR: by the time the CPU tries to load
a program from the NOR flash, the latter is still in reset
and not yet available.
Additionaly, this patch fixes a bug in the original code which
caused the reset delay to last for 2s instead of 500ms.
