AA is supposed to be the current stable branch, and the wiki provides
instructions on how to flash it on SX76x devices, requiring a
replacement of the stock locked bootloader. It says to build it along
with your image from menuconfig for the replacement. Currently, this
builds a broken bootloader that can boot only an already flashed OpenWrt
image, and you cannot reflash again without booting an older bootloader
over serial in the UART boot mode. At this moment, this device is
temporarily not supported in trunk, and this bootloader package was
dropped after the AA branch, with a new one added later. This patch
corrects the unmaintained AA bootloader to work as close to as designed
as I could manage. I made this patch mostly through trial and error, and
I don't really understand why it simply refuses to work properly without
it. Again, this patch is ONLY for AA.
