[okl4-developer] Error on Building Image

[Tsai, Tung-Chieh]

Dear Nelson,

Ya, I'm trying to port to the Android platform , and modified from the
 configuration for s3c2410. But, unless the 'head.spp,' I have changed
everything. I make every functions which need to link for kernel, to be
 empty, return 0, or just an infinite loop(Platform::reboot).

And my machines.py is below:

  class goldfish(arm926ejs):
      platform = "goldfish"
      memory = arm926ejs.memory.copy()

  class android(goldfish):
      virtual = False
      memory = goldfish.memory.copy()
      memory['physical'] = [Region(0x0, 0x6000000)]

So, as you say, I think I miss some  configuration variable.

Beside, I see my weaver.xml and s3c2410's, they're  different
in base and virtual memory address, and my version lack of some
device's address.But I can't see the what it relative to the error
message.

Thanks.

Best Regards,
Tsai, Tung-Chieh
