[ECOS] Target ek-lm3s811 with template redboot does not build

[David Fernandez <david dot fernandez dot work at googlemail dot com>]

Hi There,

May be that this is known to be incomplete (at least for redboot), but
when building for ecosconfig ek-lm3s811 redboot, I get the following
errors:
...

The first one:
/home/wifi/ecos/packages/redboot/current/src/main.c:282:34: error:
‘CYGMEM_REGION_ram’ undeclared (first use in this function)

Is obviously due to the platform assuming no "ram", but "sram"
instead, while the cyg_start() function in RedBoot expects to have it
defined in all cases.

I suspect the others are similar cases where RedBoot expects something
defined for them (I guess even if the definitions are dummies).

So it might be that this platform is not currently supported by
Redboot, or in progress, but I might be missing some package that I
should add...

Anybody knows something about this?

Cheers
