This patch will create a configuration option for a minimum configuration for
the ns16550 serial driver at drivers/serial/ns16550.c and will apply this new
configuration option to the SIMPC8313.h config file in order to fix the NAND
bootstrap build error. This option will exclude all functions with exception of
NS16550_putc and NS16550_init. This will be used primarily to save space and
remove unused code from builds in which space is limited.

1. Changes to the default environment:
- "bootcmd" defined as "run flash_self"
- "saveenv" command removed from "update"
- "uboot" changed to "u-boot" (also in "load")
- "addmtd" variable defined (and added to all boot commands)
2. CONFIG_CMD_JFFS2 defined to enable "mtdparts" command
3. MTDIDS_DEFAULT and MTDPARTS_DEFAULT defined
4. CONFIG_SYS_CBSIZE changed from 256 to 512. That solves the problem
with truncated "bootargs" environment variable.

- Extend ub_dev_read() and ub_dev_recv() so they return the length actually
read, which allows for better control and error handling (this introduces
additional error code API_ESYSC returned by the glue mid-layer).
- Clean up definitions naming and usage.
- Other minor cosmetics.
Note these changes do not touch the API proper, so the interface between
U-Boot and standalone applications remains unchanged.

De-hardcode range in RAM we search for the API signature. Instead use the stack
pointer as a hint to narrow down the range in which the signature could reside
(it is malloc'ed on the U-Boot heap, and is hoped to remain in some proximity
from stack area). Adjust PowerPC code in API demo to the new scheme.

Here's a new framework (based roughly off the linux one) for managing
MMC controllers. It handles all of the standard SD/MMC transactions,
leaving the host drivers to implement only what is necessary to
deal with their specific hardware.
This also hooks the infrastructure into the PowerPC board code
(similar to how the ethernet infrastructure now hooks in)
Some of this code was contributed by Dave Liu <daveliu@freescale.com>

The current MMC infrastructure relies on the existence of an
arch-specific header file. This isn't necessary, and a couple
drivers were forced to implement dummy files to meet this requirement.
Instead, we move the stuff in those header files into a more appropriate
place, and eliminate the stubs and the #include of asm/arch/mmc.h

The ecm variable in sdram.c was being declared for all 8548, but only
used by specific 8548 boards, so we make that variable require those
specific boards, too
The nand code was using an index "i" into a table, and then re-using "i"
to set addresses for each upm. However, then it relied on the old value
of i still being there to enable things. Changed the second "i" to "j"

This patch makes accesses to the system memory cachable by removing the
caching-inhibited and guarded flags from the relevant TLB entries for
the TQM8548_BE and TQM8548_AG modules. FYI, the Freescale MPC85* boards
are configured similarly.
This results in a big averall performace improvement. TFTP downloads,
NAND Flash accesses, kernel boots, etc. are much faster.

The TQM8548_AG module does not have the standard PCI/PCI-X interface

As the reset vector is located at 0xfffffffc, all flash sectors from the
beginning of the U-Boot binary to 0xffffffff must be protected. On the
TQM8548-AG having small sectors at the end of the flash it happened that
the last two sector were not protected and an "erase all" left an
un-bootable system behind:
Bank # 2: CFI conformant FLASH (32 x 16) Size: 32 MB in 270 Sectors

Update the 86xx reset sequence to try executing a board-specific reset
function. If the board-specific reset is not implemented or does not
succeed, then assert #HRESET_REQ. Using #HRESET_REQ is a more standard
reset procedure than the previous method and allows all board
peripherals to be reset if needed.

Previously if we >=4G of memory and !CONFIG_PHYS_64BIT we'd report

lowest priority LAWs we setup the DDR controller and the max amount

In the 36-bit physical config for MPC8572DS when need the start address
of memory and it size to be kept in phys_*_t instead of a ulong since

When we introduced the 36-bit config of the MPC8572DS board we had the
wrong PCI MEM bus address map. Additionally, the change to the address
map exposes a small issue in our dummy read on the ULI bus. We need
to use the new mapping functions to handle that read properly in the
36-bit config.
