[Skyeye-developer]blackfin on skyeye error

[kang shuo]

hi:
     Blackfin simulation is not completely  until now.Cache and DMA is
not simulated.So when you select some device that not supported by
skyeye, maybe you will encounter some problems. I tried to make the
newest release of blackfin uclinux run on skyeye and  need to wait
several days before get an enhancement blackfin simulator.  You can
try  2005R3 RC2 release of blackfin uclinux and make it run on SkyEye.

- Thanks
