Hi everybody,
the attached patch, which is against the kernel 2.6.28.10 and not the whole
OpenWRT tree, adds platform detection for the WRT160NL.
It is a butt ugly hack but it's the only solution I found working since u-boot
does not provide any variables which help in detecting this router. I wanted
to avoid changing the kernel command line since this needs either a serial
port to access u-boot or a specially built kernel.
Throw this away if you find a better way to this.
More patches will come:
- WRT160NL Ethernet
- WRT160NL TRX MTD partition table parser
Best regards,
Christian
