Hi York,
For chasis2 platforms, like ls1043a and ls1046a, similar patch has been merged already.
Patch information:
commit 4de6ce1594fcff6fa9e626d094fa922f4889e167 Author: Tang Yuantian Yuantian.Tang@nxp.com Date: Mon Aug 8 15:07:20 2016
armv8: fsl-lsch2: enable snoopable sata read and write
By default the SATA IP on the ls1043a/ls1046a SoCs does not generating coherent/snoopable transactions. This patch enable it in the SCFG_SNPCNFGCR register along with sata axicc register. In addition, the dma-coherent property must be set on the SATA controller nodes.

How about ls1043a, ls1046a? You didn't check SVR.
