My biggest concern is the amount of MCD/DMA support code. And it is
all done quite differently to everything else in the kernel. We may
get a bit of push back from kernel folk who look after DMA.
Actually, there is already a similar code in arch/powerpc/sysdev/bestcomm
(also from freescale, maybe an identical part, but I did not find any
usable doc), but the powerpc folks kept that hidden in the arch/powerpc
tree, instead of installing it in drivers/dma.
The MCD DMA or DMA FEC code from freescale has a comment implying that this
was first used in the MPC8220 part. And Montavista has a MPC8220 port, but
I did not find it, so I do not know where they installed the MCD DMA driver.
Ok, looks like there is a bit a variance in all this.
Probably the best thing to do is post the patches on the linux kernel
mailing list then, asking for direction on a dma driver.
I have no problem with it going into the arch/m68k area. So that is
always an option.
Regards
Greg
