c7190f028f mpc83xx: retain POR values of non-configured ACR, SPCR, SCCR, and LCRR bitfields
some LCRR bits are not documented throughout the 83xx family RMs.
New board porters copying similar board configurations might omit
setting e.g., DBYP since it was not documented in their SoC's RM.

Prevent them bricking their board by retaining power on reset values
in bit fields that the board porter doesn't explicitly configure
via CONFIG_SYS_<registername>_<bitfield> assignments in the board
config file.

also move LCRR assignment to cpu_init_r[am] to help ensure no
transactions are being executed via the local bus while CLKDIV is being
modified.

also start to use i/o accessors.

6e1385d5f8 NAND boot: change NAND loader's relocate SP to CONFIG param
So that we can set the NAND loader's relocate stack pointer
to the value other than the relocate address + 0x10000.

d9ac3d5a17 mpc83xx: set 64BIT_VSPRINTF for boards using nand_util
When enabling NAND support for a board, one must also define
CONFIG_SYS_64BIT_VSPRINTF because this is needed in nand_util.c
for correct output.

942556a92a mtd: MTD related config header changes (mtdparts command)
By changing the cmd_mtdparts to only use the MTD infrastructure and
not the direct interface to the CFI NOR FLASH driver we now need
to add the MTD infrastructure to all boards using those mtdparts
commands. This patch adds those components:

CONFIG_MTD_DEVICE (for all FLASH types)

plus

CONFIG_FLASH_CFI_MTD (for NOR FLASH)

To all board maintainers: Please test this on your platforms and
report any problems/issues found. Thanks.

d48eb5131d i2c: Remove deprecated individual i2c commands
The following individual I2C commands have been removed: imd, imm, inm,
imw, icrc32, iprobe, iloop, isdram.

The functionality of the individual commands is still available via
the 'i2c' command.

This change only has an impact on those boards which did not have
CONFIG_I2C_CMD_TREE defined.

c123098035 mpc83xx: Set guarded bit on BAT that covers the end of the address space
The mpc8313erdb board currently sets DBAT6 to cover all of the final 256MiB of
address space; however, not all of this space is covered by a device.  In
particular, flash sits at 0xfe000000-0xfe7fffff, and nothing is mapped
at the far end of the address space.

In zlib, there is a loop that references p[-1] if p is non-NULL.  Under
some circumstances, this leads to the CPU speculatively loading from
0xfffffff8 if p is NULL.  This leads to a machine check.

68d7d65100 Separate mtdparts command from jffs2
Currently the mtdparts commands are included in the jffs2 command support.
This doesn't make sense anymore since other commands (e.g. UBI) use this
infrastructure as well now. This patch separates the mtdparts commands from
the jffs2 commands making it possible to only select mtdparts when no JFFS2
support is needed.

f5675aa5ce Create configuration option for restricted ns16550 functions
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.

bdab39d358 rename CONFIG_CMD_ENV to CONFIG_CMD_SAVEENV
The CONFIG_CMD_ENV option controls enablement of the `saveenv` command
rather than a generic "env" command, or anything else related to the
environment.  So, let's make sure the define is named accordingly.

5bb907a492 mpc83xx: New board support for SIMPC8313
This patch will create a new board, SIMPC8313, from Sheldon Instruments.  This
board boots from NAND devices and is configureable for either large or small
page devices.  The board supports non-soldered DDR2, one ethernet port, a
Marvell 88E1118 PHY, and PCI host support.  The board also has a FPGA connected
to the eLBC providing glue logic to a TMS320C67xx DSP.
