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