This patch enables networking support for TI's J721e SoC.
Patch 1 adds a new interface to DMA uclass to get channel specific
private/configuration data. Patch 2 to 4 use this interface to pass data
from J721e's UDMA driver to CPSW ethernet driver. Last two patches add
DMA and CPSW DT nodes and configs.
I assume this series has dependencies. Right?
No compile time dependencies and system will boot to U-Boot prompt. But
for ethernet functionality to work we need base DMA support:
