b4ebeb86d1 igep00x0: default mmcrootfstype to EXT4
omap2plus_defconfig now has built-in compile support for EXT4 enabled
by default now. So, we can use EXT4 as the default root file system
type for MMC.

e5e73c17db igep00x0: default to OMAP-specific serial driver
An OMAP specific serial driver was merged on the Linux kenel a long
time ago. So, it makes sense to default the console name to OMAP
ttyO instead of the generic ttyS naming.

0d986e61e2 da850/omap-l138: Add support to read u-boot image from MMC/SD
DA850/OMAP-L138 does not support strict MMC/SD boot mode. SPL will
be in SPI flash and U-Boot image will be in MMC/SD card. SPL will
do the low level initialization and then loads the u-boot image
from MMC/SD card.

Define CONFIG_SPL_MMC_LOAD macro in the DA850/OMAP-L138
configuration file to enable this feature.

Add TLB mappings, board target options, and configuration items

Since P1022DS RevB board, the NOR flash have been changed to 16 bit/28bit
address flash, therefore, when SDHC/ESPI booting and access to eLBC,
the PMUXCR[0~1] must be set to 10b, and PMUXCR[9~10] must be set to
00b for them.

Configure the PX_BRDCFG0[0~1] to 10b which is connected to
SPI devices as SPI_CS(0:3)_B.

c9718210b1 powerpc/82xx: use SDRAM detection for mgcoge2ne
mgcoge2ne was an intermediate step towards mgcoge3ne. One difference is the
smaller SDRAM on mgcoge2ne (128MB). To support both boards with the same
u-boot we use here the SDRAM detection.

This patch enables SDRAM detection between 256MB and 128MB.
So in addition to the existing 256MB geometry:
     4 chips x 8M (13 rows, 10 cols) x 16 bit x 4 banks
we can now also have 128MB geometry:
     4 chips x 4M (13 rows,  9 cols) x 16 bit x 4 banks

63905f1616 tegra: define fdt_load/fdt_high variables
These variables act like loadaddr, but for a device tree image. Defining
them in the environment allows boot scripts to be identical on Tegra20 and
Tegra30, which have different memory base addresses, and hence need
different values for these variables.

dd8ab95344 tegra: enable bootz command
bootz is just like bootm, except that it can boot a raw zImage, without
requiring it to be wrapped inside a uImage.

f78d348cb8 tegra: bootcmd: start USB only when needed
Instead of initializing USB as soon as bootcmd is executed, defer it
until the first boot device that (potentially in the case of network)
uses USB is scanned. This avoids initializing USB when booting from MMC,
so speeds that up.

03cddf28eb tegra: bootcmd enhancements
Place the list of searched boot devices, file-system types, boot file
locations/prefixes, and boot script names into variables. This allows
the user to override them directly (e.g. to change boot order, or select
the specific values they use) without having to edit the main bootcmd
and script_boot variables.

The default boot order is changed from USB, MMC, DHCP to MMC, USB, DHCP.
This speeds up the typical MMC boot case. People who want USB boot can
now edit variable boot_targets appropriately.

Also, reformat BOOTCMDS_COMMON to fit within 80 columns.

Potential future enhancements might be:
* Allow boards to specify which of bootcmd_mmc0/... should be defined,
  based on the HW they contain.
* Allow boards to influence the order that the boot targets are added
  into the boot_targets variable.

9cd3f3adf0 tegra: add enterrcm command
Tegra's boot ROM supports a mode whereby code may be downloaded and flash
programmed over a USB connection. On dev boards, this is typically entered
by holding down a "force recovery" button and resetting the CPU. However,
not all boards have such a button (one example is the Compulab Trimslice),
so a method to enter RCM from software is useful.

This change implements the command "enterrcm" to do this, and enables it
for all Tegra boards by default. Even on boards other than Trimslice,
controlling this over a UART may be useful, e.g. to allow simple remote
control without the need for mechanical button actuators, or hooking up
relays/... to the button.
