[POWERPC] bestcomm: core bestcomm support for Freescale MPC5200 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.
[POWERPC] bestcomm: ATA task support This is the microcode for the ATA task and the associated support code. The microcode itself comes directly from the offical API (v2.2) Signed-off-by: Sylvain Munaut <tnt@246tNt.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

[POWERPC] bestcomm: GenBD task support This is the microcode for the GenBD task and the associated support code. This is a generic task that copy data to/from a hardware FIFO. This is currently locked to 32bits wide access but could be extended as needed.
