The ml300 support has not been contributed to the public eCos source
tree, so I do not know who did the work or exactly what is in the
release you have been given. Certainly it looks like whoever made this
release skimped on the releng QA: the sources you have been supplied
do not match the RedBoot build.

First, these messages:
    ecos.db, package CYGPKG_HAL_M68K_MCF52xx_MCF5272_MCF5272C3: warning
          Version subdirectory `current' does not have a CDL script
    `hal_m68k_mcf52xx_mcf5272_mcf5272c3.cdl'.
    ecos.db, package CYGPKG_HAL_M68K_MCF52xx_MCF5272_MCF5272C3: warning
          This package does not have any valid version subdirectories.

These are just warnings so you can ignore them, but it may be possible
to fix them fairly easily. Look for a directory
packages/hal/m68k/mcf52xx/mcf5272/mcf5272c3/plf/current. This should
contain a file hal_m68k_mcf52xx_mcf5272_mcf5272c3.cdl. If there is a
.cdl file there with a different name, just rename it. Otherwise
create an empty file with that name - the contents do not matter
unless you try to build eCos for that target.

It looks like you have correctly figured out the basic process for
rebuilding RedBoot:

  $ ecosconfig new <target> redboot
  $ ecosconfig import <.ecm file>
  $ ecosconfig tree
  $ make

xilinx_ml300 would seem to be a valid target in the release you have
been given. ml300 might work as well, usually one or more aliases are
provided for any given target.

Now for the real problem:

    The savefile contains a cdl_option for an unknown option
     `CYGHWR_DEVS_FLASH_AMD_TH50VSF258'
    Invalid savefile
    "/mnt/hda7/mind/Virtex2Pro/src/ecos/packages/hal/powerpc/ml300/current/misc/redboot_RAM.ecm".

Presumably the xilinx_ml300 board uses a th50vsf258 flash chip. I
don't have any information on this part, but I guess it is just
another AMD-compatible flash chip. Whoever did the xilink_ml300 port
added support for this chip to the AMD flash device driver package in
packages/devs/flash/amd/am29xxxxx/current, but then shipped an older
version of the driver. That makes it impossible to rebuild RedBoot. I
suggest contacting whoever provided the release and asking for the
right version of the driver.
