I have no idea how difficult it will be to build today, but it's a MIPS CPU core so I should be able to do it with a cross-compiled MIPS GCC. I've also found the AR5523 datasheet here. So, poke me if you'd like me to look up what's going on. It honestly looks like a MIPS core with a USB device controller and an AR5212 MAC (the datasheet refers to the AR5212 MAC/BB documentation, so it's quite likely exactly that.) On the up side, it's a 30MHz MIPS4kp core with 256KiB of SRAM and some SPI flash for booting. So it's entirely plausible we could write a replacement firmware for it based on the FreeBSD AR5212 HAL code (and whatever extra AR5523 specific mac/bb initvals and calibration data format.) In _fact_, since it's basically an AR5212 glued on the side, we could plausibly extend ath5k and the FreeBSD ath driver to do what ath9k_htc does. :-) Ok, that's enough carrot-on-a-stick for y'all.
