Software-only emulator of ROM emulator: I added ROM programming subroutine to my "custom" LinuxBIOS and wrote primitive protocol driver for minicom. That's all. Now, how it goes: 1. I tell LinuxBIOS to start in "resque mode"; 2. When it prompts (about a second) I send image file from minicom, which also is a serial console of the target system; 3. Resque code loads gzipped ROM image from host system using serial_fill_inbuf and then programs system flash. As I have only 2MB ROM on target, it doesn't take much time to load ROM image into the target's RAM. Bur there's also TFTP loader in LinuxBIOS, if anyone need higher speed.
