+Subject: [PATCH] ahci_qoriq: bug fix for ecc_addr
+
+Original driver expect a register node with name "sata-ecc"
+this node is of 64 bit wide.
+In ACPI such nodes can be provided with QWordMemory, but
+QWordMemory can not hold DescriptorName more than 4 characters.
+
+Therefore this patch changes platform property retrival based
+upon index instead of named.
+
