[PATCH] memory: ti-gpmc: Fix lock up at A53 SPL during NAND boot on AM64-EVM

AM64 ES2.0 bootrom seems to enable WAIT0EDGEDETECTION interrupt. This causes a lockup at A53 SPL when accessing NAND controller or ELM registers. A good option would be to softrest GPMC block at probe but this cannot be done for AM64 as SOFTRESET bit is marked as reserved in SYSCONFIG register.
