Subject: ISA dma on 4xx
Date: Thu, 5 Dec 2002 14:36:38 +1100 [thread overview]
Message-ID: <15854.51654.206530.977151@argo.ozlabs.ibm.com> (raw)
Is anyone using a pc-style southbridge chip in a 4xx-based system?
I am thinking that the split that we currently have in linuxppc-2.5,
where asm/dma.h includes either ppc4xx_dma.h or ppc_isa_dma.h, is not
the best way to do things, because we might want to use the ISA dma
functions on a 4xx system.
Does anyone use the 4xx dma controller with some device that is
normally connected to an ISA bus? That is, is there a need for the
4xx dma functions to provide the same interface as the ISA dma
functions?
Paul.
