Currently, some linker scripts are found by common code in config.mk.
Some are found using CONFIG_SYS_LDSCRIPT, but the code for that is
sometimes in arch config.mk and sometimes in board config.mk. Some
are found using an arch-specific rule for looking in CPUDIR, etc.
Further, the powerpc config.mk rule relied on CONFIG_NAND_SPL
when it really wanted CONFIG_NAND_U_BOOT -- which covered up the fact
that not all NAND_U_BOOT builds actually wanted CPUDIR/u-boot-nand.lds.
Replace all of this -- except for a handful of boards that are actually
selecting a linker script in a unique way -- with centralized ldscript
finding.
If board code specifies LDSCRIPT, that will be used.
Otherwise, if CONFIG_SYS_LDSCRIPT is specified, that will be used.
If neither of these are specified, then the central config.mk will
check for the existence of the following, in order:
$(TOPDIR)/board/$(BOARDDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/$(CPUDIR)/u-boot-nand.lds (only if CONFIG_NAND_U_BOOT)
$(TOPDIR)/board/$(BOARDDIR)/u-boot.lds
$(TOPDIR)/$(CPUDIR)/u-boot.lds
Some boards (sc3, cm5200, munices) provided their own u-boot.lds that
were dead code, because they were overridden by a CPUDIR u-boot.lds under
the old powerpc rules. These boards' own u-boot.lds have bitrotted and
no longer work -- these lds files have been removed.

In order to support boardId / hwkey lists, the u-boot default
environment has been updated: Added a script checkboardidlist
which checks the list of boardId / hwkey if the boadrId / hwkey
of the IVM is included in that list. This feature is used if you
got different HW variants but you only want to create one boot
package. E.g. supx5 board series.

Add:
- introduce "bootrunner" environment variable
This allows to execute consecutive different commands
specified in the list "subbootcmd". If one command fails
the command serie will stop.
- introduce environment variable "develop", "ramfs" and "release"
Each variable is one way to boot our linux. "develop" is for
development purpose and boots the SW via NFS. "release" is for
booting the linux image from flash, "ramfs" allows to load an SW
image via tftp into ram and executes from there
- introduce "addmem" variable, this command adds the used memory
for linux to the bootargs
- introduce "addvar" variable, this command adress for the /var
directory to the kernel command line
- introduce "setramfspram" and "setrootfsaddr" these calculation
were done if "ramfs" was used (only for debugging)
- introduce "tftpramfs" used for "ramfs" to load the image into
RAM (only for debugging)
Remove unneeded stuff:
- CONFIG_IO_MUXING is obsolete for keymile boards
- CONFIG_KM_DEF_ENV_PRIVATE is also obsolete
- define CONFIG_SYS_TEXT_BASE in board configs only

The mgcoge2 board from keymile deploys two different processors.
An ARM based Kirkwood for the "unit" part of the SW and a PPC for
the "ne" part of the SW. Therefore in Linux and U-Boot the names
for the board are mgcoge2un and mgcoge2ne. This patch adds the
mgcoge2ne part of the board. The ppc part of mgboge2 is quite
similar to mgcoge, therefore a generic header km82xx-common.h
was introduced to collect all similiarities. Currently the only
difference is that mgcoge2ne has a 64 MB numonyx NOR flash with
a single die. The mgcoge has a dual die flash 2*32MB from spansion.

29.7.8 Multi-block Read

to read has been defined by previous CMD23 for MMC, or pre-defined number
of blocks in CMD53 for SDIO/SDCombo,or whatever multi-block read without
abort command at card side, an abort command, either automatic or manual
CMD12/CMD52, is still required by ESDHC after the pre-defined number of
blocks are done, to drive the internal state machine to idle mode. In this
case, the card may not respond to this extra abort command and ESDHC will
get Response Timeout. It is recommended to manually send an abort command
with RSPTYP[1:0] both bits cleared.

Use the 'video-mode' environment variable (for Freescale chips that have a
DIU display controller) to designate the full video configuration. Previously,
the DIU driver used the 'monitor' variable, and it was used only to determine
the output video port.
The old definition of the "monitor" environment variable only determines
which video port to use for output. This variable was set to a number (0,
1, or sometimes 2) to specify a DVI, LVDS, or Dual-LVDS port. The
resolution was hard-coded into board-specific code. The Linux command-line
arguments needed to be hard-coded to the proper video definition string.
