This patch adds framework for dual format images. Format detection is added
and the bootm controll flow is updated to include cases for new FIT format
uImages.

When the legacy (image_header based) format is detected appropriate
legacy specific handling is invoked. For the new (FIT based) format uImages
dual boot framework has a minial support, that will only print out a
corresponding debug messages. Implementation of the FIT specific handling will
be added in following patches.

This is a compatibility step that allows both the older form
and the new form to co-exist for a while until the older can
be removed entirely.

All transformations are of the form:
Before:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT)
After:
    #if (CONFIG_COMMANDS & CFG_CMD_AUTOSCRIPT) || defined(CONFIG_CMD_AUTOSCRIPT)

Fix bug introduced by "Fix get_partition_info() parameter error in all
other calls" from 2005-03-04 in cmd_ide.c and cmd_scsi.c, which prevented
to use diskboot or scsiboot form another device than 0.

Block device read/write is anonymous data; there is no need to use a
typed pointer.  void * is fine.  Also add a hook for block_read functions

Patch by Denis Peter, 06 Dec 2004

  (common/cmd_ide.c, common/cmd_reiser.c, common/cmd_scsi.c).

* Enable USB and IDE support for INKA4x0 board

* Patch by Andrew Dyer, 28 February 2005:
  fix ext2load passing an incorrect pointer to get_partition_info()
  resulting in load failure for devices other than 0

  makes 'ld' to overlook binary objects compatibility.

* Moved $(PLATFORM_LIBS) from the library group (--start-group ...
  --end-group) outside of the group. This will make 'ld' to do
  _multiple_ search in the library group when resolving symbol
  references and do only a _single_ seach in libgcc.a after the group
  search.

* Fix stability problems on CPC45 board again.

* Make image detection for diskboot / usbboot / scsiboot more robust
  (also check header checksum)

(autoscript, bmp, bsp, fat, mmc, nand, portio, ...)

  - remove trailing white space, trailing empty lines, C++ comments, etc.
  - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)

* Patches by Kenneth Johansson, 25 Jun 2003:
  - major rework of command structure
    (work done mostly by Michal Cendrowski and Joakim Kristiansen)

  - Splashscreen support
  - modem support
  - sysmon support
  - temperature dependend enabling of LCD

* Allow booting from old "PPCBoot" disk partitions

* Add support for TQM8255 Board / MPC8255 CPU
