This patch adds support for the core of the BestComm API for the Freescale MPC5200(b). The BestComm engine is a microcode-controlled / tasks-based DMA used by several of the onchip devices. Setting up the tasks / memory allocation and all common low level functions are handled by this patch. The specifics details of each tasks and their microcode are split-out in separate patches. This is not the official API, but a much cleaner one. (hopefully) Signed-off-by: Sylvain Munaut <tnt@246tNt.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

BestComm is the name of the communication coprocessor found
|
|
on the Freescale MPC5200 family of processor. It's usage is
|
|
optionnal for some drivers (like ATA), but required for
|
|
others (like FEC).
|
|
|
|
If you want to use drivers that require DMA operations,
|
|
answer Y or M. Otherwise say N.
