NAK, looking and the code - secondary DMA base is only used
by siimage.c and sgiioc4.c (both use ->mmio == 2, for siimage
->dma_base2
is unused, for sgiioc4 it is used for some weird DMA transfer ending
stuff)
Hm, concerning the other field of ide_hwif_t, dma_master: I currently see
no users to it but pdc202xx_old.c. The way it's computed makes it dependent on
what channels are enabled (though all channels are forced present in that
driver by the most recent patch) which makes it invalid if the primary channel
happens to be disabled. I'd like to replace it with extra_base fields which
would point to the extra DMA ports regardless of the channels present/enabled,
is this OK?
WBR, Sergei
