I did a quick review,  I don't think adding this patch would break
anything.  The files need a proper u-boot style file header but that is
easily fixed.  Some of the ifdef's are a bit confusing to me but a
better way to do it does not jump out at me.  I can apply this to u
-boot-linaro.

In the longer term it would be great if the Calxeda folks (Jason and
Rob) could sign off on this and if Rob could send a patch upstream since
he is the defacto u-boot pxe maintainer having sent the most recent
fixed upstream.

Of course this is all based on if Justin and Dave still want this
functionality in or are happy with the alternative method that Jason
outlines in comment #2 above.

Title:
  PXELINUX implementation doesn't respect dhcp ConfigFile or PathPrefix
  values

Status in Linaro U-Boot:
  New
Status in “u-boot-linaro” package in Ubuntu:
  In Progress

Bug description:
  The part implementation of PXELINUX in uboot doesn't respect RFC5071 dhcp options:
     o  "MAGIC" - 208 - An option whose presence and content verifies to
        the PXELINUX bootloader that the options numbered 209-211 are for
        the purpose as described herein.

     o  "ConfigFile" - 209 - Configures the path/filename component of the
        configuration file's location, which this bootloader should use to
        configure itself.

     o  "PathPrefix" - 210 - Configures a value to be prepended to the
        ConfigFile to discern the directory location of the file.

     o  "RebootTime" - 211 - Configures a timeout after which the
        bootstrap program will reboot the system (most likely returning it
        to PXE).

  These have the obvious interest in being able to provide customised
  config and kernels at run time.

  Thanks.
