Oleg, you reserve 128K for "small custom bootloader", 128K is more than
enough to use RedBoot. If you can donate 128K for boot-loader then use
RedBoot.  I am sure that RedBoot can run and your "ROMROM" applications.
If standard RedBoot lacks some behaviors, just provide new functionality
with custom RedBoot command(s) FYI: this code can be part platform HAL.

Paraphrasing  Greenspun's Tenth Rule, Any custom boot-loader for eCos
will contain an ad hoc, informally-specified, bug-ridden, implementation
of half of RedBoot :-)

I assure you if you can donate 128K for your own bootstrap code then
using RedBoot will save your time and efforts.

Sergei
