Good day to all!
bfe driver ported as client of siba bus, it`s worked, but work not done.
To dirty code :)
Question to FreeBSD MIPS guru:
Maybe problem in me low experience in FreeBSD internals, but I thing bus_dmamem_alloc and bus_dmamem_load
ignore "alignment" attribute passed to bus_dma_tag_create.
BFE need DMA descriptors page to be aligned to 4096, but I done this alignment only with set descriptors count from 128 to 512
Next question, how I can start init (without "write fault at 0x2003821"), if someone know
boot -tftp -raw -addr=0x807963c0 -max=0x770000 192.168.0.90:kernel.tramp.bin
