This patch reworks all headerfiles for keymile boards. Furthermore
the environment variables are refactored.

Changes:
  - introduce km-powerpc.h file and extract ppc specific parts to it
  - move ARM specific options and vaiables to km_arm.h
  - sort the environment variables to logical groups
  - enhance the description of the environment variables
  - remove KM specific HW key and board id from kernel command line

For freescale i.MX53 eSDHCv2, when using CMD12, cmdtype need
to be set to ABORT, otherwise, next read command will hang.

This is a software Software Restrictions in i.MX53 reference manual:

29.7.8 Multi-block Read
For pre-defined multi-block read operation, that is,the number of blocks
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.

	video-mode=<driver>:<xres>x<yres>-<depth>@<freq><,option=string>

	<driver> The video driver, ignored by U-Boot
	<xres> The X resolution (in pixels) to use.
	<yres> The Y resolution (in pixels) to use.
	<depth> The color depth (in bits) to use.
	<freq> The frequency (in Hz) to use.
	<options> A comma-separated list of device-specific options

There seems to be tools producing incorrect 'end of bitmap data'
markers '0100' in a RLE bitmap. Drawing such bitmaps can result
in overwriting memory above the frame buffer. E.g. on MPC5121e
based boards this memory can contain U-Boot environment.

We may not rely on the correct end of bitmap data marker 0001
only, but also have to check whether we are going to draw a
valid frame buffer scan line.

The patch provides a fix by maintaining a pixel counter
which is incremented by the amount of pixels we are going
to draw. If the counter exceeds frame buffer pixels limit
we stop the drawing with the error message.

u-boot environments, esp. when boards are shared across multiple
users, can get pretty large and time consuming to visually parse.
The grepenv command this patch adds can be used in lieu of printenv
to facilitate searching.  grepenv works like printenv but limits
its output only to environment strings (variable name and value
pairs) that match the user specified substring.

the following examples are on a board with a 5313 byte environment
that spans multiple screen pages:

Example 1:  summarize ethernet configuration:

=> grepenv eth TSEC
etact=FM1@DTSEC2
eth=FM1@DTSEC4
ethact=FM1@DTSEC2
eth1addr=00:E0:0C:00:8b:01
eth2addr=00:E0:0C:00:8b:02
eth3addr=00:E0:0C:00:8b:03
eth4addr=00:E0:0C:00:8b:04
eth5addr=00:E0:0C:00:8b:05
eth6addr=00:E0:0C:00:8b:06
eth7addr=00:E0:0C:00:8b:07
eth8addr=00:E0:0C:00:8b:08
eth9addr=00:E0:0C:00:8b:09
ethaddr=00:E0:0C:00:8b:00
netdev=eth0
uprcw=setenv ethact $eth;setenv filename p4080ds/R_PPSXX_0xe/rcw_0xe_2sgmii_rev2_high.bin;setenv start 0xe8000000;protect off all;run upimage;protect on all

=>

Example 2: detect unused env vars:

=> grepenv etact
etact=FM1@DTSEC2
=>

Example 3: reveal hardcoded variables; e.g., for fdtaddr:

=> grepenv fdtaddr
fdtaddr=c00000
nfsboot=setenv bootargs root=/dev/nfs rw nfsroot=$serverip:$rootpath ip=$ipaddr:$serverip:$gatewayip:$netmask:$hostname:$netdev:off console=$consoledev,$baudrate $othbootargs;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr - $fdtaddr
ramboot=setenv bootargs root=/dev/ram rw console=$consoledev,$baudrate $othbootargs;tftp $ramdiskaddr $ramdiskfile;tftp $loadaddr $bootfile;tftp $fdtaddr $fdtfile;bootm $loadaddr $ramdiskaddr $fdtaddr
=> grep $fdtaddr
fdtaddr=c00000
my_boot=bootm 0x40000000 0x41000000 0x00c00000
my_dtb=tftp 0x00c00000 $prefix/p4080ds.dtb
nohvboot=tftp 1000000 $dir/$bootfile;tftp 2000000 $dir/$ramdiskfile;tftp c00000 $dir/$fdtfile;setenv bootargs root=/dev/ram rw ramdisk_size=0x10000000 console=ttyS0,115200;bootm 1000000 2000000 c00000;

commit 560d424b "env: re-add
support for auto-completion" fell short of its description -
the 'used' logic in hmatch_r was reversed - 'used' is 0 if
the hash table entry is not used, or -1 if deleted.  This
patch makes hmatch_r actually match on valid ('used') entries,
instead of skipping them and failing to match anything.

typing 'printenv tft' and hitting 'tab' now displays valid
choices for variable names.
