# Porting OpenWrt to a board with a supported SoC
## Update
[The decide tree for this device has been corrected and succesfully merged. Snapshot are now available!](https://git.openwrt.org/?p=openwrt/openwrt.git;a=commit;h=b108ed0ab09492d8d5a1775714da1ee34ce475ee)
## Intro
Recently, some network devices caught my attention both on Aliexpress and Alibaba. Specifically, I found some interesting outdoor equipment for a very low price, ranging between 10-25$.

## Notes
#### On the 0x9f bootcmd prefix
MIPS has different areas, called "kseg", some are cached, some are uncached and some are mapped somewhere, some are not. In this SoC there's a special integrated peripheral that knows how to read from SPI NOR memory and it provides the results in a memory-mapped way, that is, CPU can execute from it directly. I think 0x9f is one of the regions where it's mapped to (another common region is 0xbf).
