[ECOS] change default RedBoot "fis load" and "exec" - how?

[Tomasz Chmielewski <mangoo@wpkg.org>]

I have a Freecom FSG-3 device (ARM, IXP425 network, RedBoot).

By default, RedBoot starts Linux in the following way:

RedBoot> fis load kern1
RedBoot> exec -c "console=ttyS0,115200 root=/dev/hda1 mem=64M@0x00000000"

kern1 sits on /dev/mtd1, as seen here from Linux:


# cat /proc/mtd
dev:    size   erasesize  name
mtd0: 00040000 00020000 "RedBoot"
mtd1: 00180000 00020000 "kern1"
mtd2: 00180000 00020000 "kern2"
mtd3: 00020000 00020000 "RedBoot config"
mtd4: 00020000 00020000 "FIS directory"


I compiled my own kernel, saved it to /dev/mtd2 (kern2), and boot it as 
follows:

RedBoot> fis load -b 0x00020000 kern2
RedBoot> exec

To do this, I have to ctrl+C when device boots, and type the appropriate 
"fis load..." and "exec" commands.

Is there an easy way to make these new "fis load..." and "exec" commands 
the default ones for RedBoot?

I don't have a JTAG pinout for this device, so I wouldn't like to 
compile RedBoot from scratch, then flash it, and possibly brick the device.

I checked RedBoot documentation, but didn't find any commands to just 
update the default startup commands.
