AR300M -- ath79 NAND Functional?

I've been working on a similar device under the ath79 NAND target, but it appears that there might not be SPI-attached NAND support for the ath79 architecture, at least for the qca95xx SoCs.

If you have an AR300M with NAND, have you been able to install the ath79 NAND firmware from master and successfully boot?
