It is indeed the proper list for such questions and I was about to
post an answer to your previous query. Note: this is a volunteer
project - you should not expect an answer immediately.
As for how RedBoot uses the FLASH, there is a very complete section
on this in the manual:
http://sources.redhat.com/ecos/docs-latest/redboot/redboot-guide.html
RedBoot provides tools/commands to manipulate the FLASH. These are
the 'FIS' (FLASH Image System) and 'FCONFIG' (FLASH Configuration).
With these commands, images (files) can be stored in FLASH, loaded
into memory from FLASH, etc, as well as some persistent data kept
in FLASH. The layout of the FLASH device is automatically detected
by RedBoot. By default, you will get an image for RedBoot itself
(typically at the bottom of the FLASH device, but this depends on
the target), a directory of images (kept in the FLASH as a separate
image) and FCONFIG data. e.g.
RedBoot> fis list
Name FLASH addr Mem addr Length Entry point
RedBoot 0x60000000 0x60000000 0x00040000 0x00000000
RedBoot config 0x60F80000 0x60F80000 0x00001000 0x00000000
FIS directory 0x60FC0000 0x60FC0000 0x00040000 0x00000000
