[Skyeye-developer] testsuite blackfin

[kang shuo]

Now , simulation for blackfin is not very completely. Cache and Dma is not
simulated.So you need to config the kernel to disable DMA and cache. I ever
made it work based on the old version of blackfin-uclinux. I will try the
uClinux-dist-R05R4-RC2 version of blackfin in serveral days.Hope I can
improve the blackfin simualtion of SkyEye.
