Add support for Teltonika RUT104 3G HSUPA router.
This has been supported since about 20 years in the upstream Linux
kernel after initial contribution by Paulius Zaleckas from Teltonika.
It has some historical significance because I think it was one of the
first Teltonika Linux-based 3G routers.
Installation from scratch is done using the UART:
- UART soldering instructions with picture are available on the
Link: (see bottom of committ message).
- First *diet down* your OpenWrt build as minimal as you can,
I really mean this, delete everything you don't need. There
is not much RAM to go around.
- Extract the "factory" firmare which is essentially just a tar.gz
archive:
tar xvfz openwrt-gemini-generic-teltonika_rut104-squashfs-factory.bin
From the RedBoot menu:
- Do NOT UNDER ANY CIRCUMSTANCE try to use the "upgrade firmare" (Z)
alternative!
- Extract the three files zImage, rd.gz and hddapp.tgz from the archive.
- Put these three files in the root directory of your TFTP server
(usually /var/lib/tftpboot)
- Hit 6 and set up the IP address for your device (e.g. 169.254.1.2 if
you're using local link).
- Hit Y to "Upgrade Kernel", enter TFTP and your hosts IP number and
type zImage. The kernel should upload and flash.
- Hit R to "Upgrade Ramdisk", enter TFTP and your hosts IP number and
type rd.gz. The "ramdisk" (i.e. the second part of the kernel)
should upload and flash.
- Hit A to "Upgrade Application", enter TFTP and your hosts IP number
and type hddapp.tgz. The "application" (i.e. the root filesystem)
should upload and flash.
This has a 1024KB Kernel partition, just extend the existing Make
functions to handle also this. The initramfs is 0x500000 instead
of 0x600000 for this one so add a parameter explicitly parameterizing
the initramfs size.
Mark non-default due to the small RAM and flash on this device.
I currently have no idea how to actually talk to the modem on this
thing but it is probably using the high-speed "modem UART" of the
Gemini. I'd be willing to help whoever wants to experiment with
it.

The Raidsonic devices do not use a 2048k kernel "Kern"
partition like the Storlink reference designs. Instead
it uses a 3072k partition to fit a slightly
larger kernel.
Sadly the current OpenWrt Gemini kernel is still bigger
than 3072k so we need to make use of the Ramdisk
partition as well.
Create a special "copy-kernel" version that can deal
with the Raidsonic 3072k kernels. Tested on the
Raidsonic IB-4220-B booting kernel v6.12.66.
Fix a copy/paste error in the image generation makefile
while we are at it.

Make treat copy-kernel.o as intermediate and delete it when it's no
longer needed. This can fail when the same submake was triggered
multiple times for different devices.

This package just contains a small Gemini-only assembler
bootstrap loop to copy the kernel from the two fragments
(previously zImage at 0x01600000 and initramdisk at 0x00800000)
into one big zImage of up to 8 MB at 0x00400000.
It will be built on demand from the Gemini image Makefile.
