Hi Joel,
We use "evb-ast2600a1-spl_defconfig" for S6Q system.

Not much difference:
1. RGMII for mac2 and enable mdio3 function pins
2. spi2 for BIOS flash
3. mac delay for mac2/mac3 to prevent network abnormal after A/C
4. I2C buses enabled according to S6Q platform

Does it mean you'd like to add the additional common dts for AST2600 ?
