Sure Vadim,
It seems the existing Makefile.mtk isn't compatible with the current makefile scheme so nothing would happen when it was called.
I modified it to match better the other Makefile structure and now I can compile a loader_mtk.mtkram.bin file.
Sadly the resulting binary doesn't yet work on the sciphone dream g2 hardware that I have. There are some compiler warnings that may need fixing or maybe the code needs more fundamental change after rotting a bit.
My goal is to get back to the "last good state" for the schiphone dream g2 and then use that as a starting point for work with mtk6260 aka fernvale board and related devices.
Thanks! Craig
