+Subject: [PATCH 12/93] armv8: LSCH2 early and final mmu needs matching NS
+ attribute
+
+When switching between the early and final mmu tables, the stack will
+get corrupted if the Non-Secure attribute is different. For ls1043a,
+this issue is currently masked because flush_dcache_all is called
+before the switch when CONFIG_SYS_DPAA_FMAN is defined.
