[U-Boot] [PATCH v5 00/15] bmips: add bcm6348-enet support

[Álvaro Fernández Rojas]

In order to add bcm6348-enet support, dma-uclass must be extended to support
dma channels and reworked to operate like the other dm uclass (clk, reset...).

v5: Fix issues reported by Grygorii Strashko and other fixes:
 - Fix build of ti-edma3.
 - Remove unused bcm6348-iudma defines.
 - Increment bcm6348-iudma rx descriptors.
 - Fix bcm6348-iudma flow control issues.
 - bcm6348-iudma error checking now depends on hw.
 - Remove unneeded bcm6348-iudma interrupts.
 - Receive as much packets as possible from bcm6348-eth and cache them in
 net_rx_packets. This is needed in order to fix flow control issues.
v4: Fix issues reported by Grygorii Strashko and other fixes:
 - Remove usage of net_rx_packets as buffer from bcm6348-iudma.
 - Allocate dynamic rx buffer on bcm6348-iudma.
 - Copy received dma buffer to net_rx_packets in order to avoid possible
 dma overwrites.
 - Check dma errors and discard invalid packets.
 - Reset dma rx channel when sending a new packet to prevent flow control
 issues.
 - Fix packet casting on bcm6348_eth_recv/send.
v3: Introduce changes reported by Simon Glass:
 - Improve dma-uclass.h documentation.
 - Switch to live tree API.
v2: Introduce changes reported by Vignesh:
 - Respect current dma implementation.
 - Let dma_memcpy find a compatible dma device.
Other changes:
 - Fix bcm6348-iudma rx burst config.
