-Subject: [PATCH] soc: fsl: handle RCPM errata A-008646 on SoC LS1021A
-
-Description:
-       - Reading configuration register RCPM_IPPDEXPCR1
-         always return zero
-
-Workaround:
-       - Save register RCPM_IPPDEXPCR1's value to
-         register SCFG_SPARECR8.(uboot's psci also
-         need reading value from the register SCFG_SPARECR8
-         to set register RCPM_IPPDEXPCR1)
-
-Impact:
-       - FlexTimer module will cannot wakeup system in
-         deep sleep on SoC LS1021A
