Hi all,
we are currently porting OFW to a custom board (codename Neptune) with
is much like OLPC, but without SuperIO and keyboard controller.
First of all: is there any documentation about how to add a new custom
platform? As a beginner I just copied lxdevel directory to one called
neptune, changed some definitions inside:
* Makefile
* neptune.bth (taken from lxdevel.bth)
* config.fth
Is this correct?
Of couse, it's a bit hard for me to figure out, for example, where to
look for some basic initialization (e.g. PLL, SDRAM, memory mapping).
AFAIK the "official" documentation is here:
http://www.firmworks.com/open_firmware/literature/
among these documents is there also a guide for porting OFW or about OFW
"internals"? ("Open Firmware Command Reference" seems the closest to my
needs)
Thanks in advance and Best Regards,
