   4 Subject: [PATCH] ahci_qoriq: bug fix for ecc_addr
   5
   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.
  10
  11 Therefore this patch changes platform property retrival based
  12 upon index instead of named.
