I have ecos/redboot running on an EP9307 based board using the ep93xx
port found on the Cirrus Logic website.

The patch can be found in the "crater" release they put out. You can get
the source at:

http://arm.cirrus.com/files/linux/releases/linux-2.6/1.0.3/linux_1-0-3-s
rc.tar.bz2

That tarball consists of a really crippled buildroot with only some of
the packages that buildroot has. In it under ./packages/bootloader/ecos
you will find the ecos-edb93xx.patch. Ignore the other patches, they are
not really necessary and the ecos-flashP30.patch doesn't work correctly.

I'm not sure where the edb93xx support originated from but the main
"Author(s)" listed in the patch are: gthomas, hmt, nickg, and jskov.

The edb93xx patch above might not be totally complete but it does boot
RedBoot and executes Linux with no problems on my hardware.

UART1 support is there along with Ethernet and Flash support. The stubs
appear to be there for UART2 and UART3 but I have not had a chance to
figure out what is needed to get them to work.

I really would like to see the ep93xx supported in the cvs. If there is
anything I can do to help let me know.
