Installation
------------
1. Download the OpenWrt initramfs-image. Place it into a TFTP server
root directory and rename it to 1401A8C0.img. Configure the TFTP
server to listen at 192.168.1.66/24.
2. Connect the TFTP server to the access point.
3. Connect to the serial console of the access point. Attach power and
interrupt the boot procedure when prompted (bootdelay is 1 second).
4. Configure the U-Boot environment for booting OpenWrt from Ram and
flash:
$ setenv boot_openwrt 'setenv bootargs; bootm 0xbf080000'
$ setenv ramboot_openwrt 'setenv serverip 192.168.1.66;
tftpboot; bootm'
$ saveenv
5. Load OpenWrt into memory:
$ run ramboot_openwrt
Wait for the image to boot.
6. Transfer the OpenWrt sysupgrade image to the device. Write the image
to flash using sysupgrade:
$ sysupgrade -n /path/to/openwrt-sysuograde.bin

While most of the target's contents are split into subtargets, the
base-files are maintained for the target as a whole.
However, OpenWrt already implements a mechanism that will use (and
even prefer) files in the subtargets' directories. This can be
exploited to make several scripts subtarget-specific and thus save
some space (especially helpful for the tiny devices).
The only script remaining in parent base-files is
/etc/hotplug.d/ieee80211/00-wifi-migration, everything else is
moved/split.
Note that this will increase overall code lines, but reduce code
per subtarget.
base-files ipk size reduction:
master (generic) 49135 B
split (generic) 48533 B (- 0.6 kiB)
split (tiny) 43337 B (- 5.7 kiB)
split (nand) 44423 B (- 4.6 kiB)
Tested on TL-WR1043ND v4 (generic) and TL-WR841N v12 (tiny).
