Looking for ARM SoC porting guidelines

I'm working on a port the latest Linux kernel to a Nuvoton N32905 - a very inexpensive ARM9 based SoC similar to the Freescale iMX23 in many respects. My hope is that my code for this SoC will eventually reach the mainline kernel, but the whole process a fairly daunting task to a kernel newbie suc
