+Subject: [PATCH] boot: Enable firmware node initialization
+
+Enable the firmware node initialization, so that the next stage
+(hypervisor) could share the EL2 with firmware (boot-wrapper). The next
+stage (hypervisor) get the smccc entry point, code/data sections, the
+sections attrs and firmware node version and so on.
+It is worth noting that this EL2 sharing mechanism is only for Armv8R
+AArch64, thus add flag_v8r to record if the arch is Armv8R AArch64.
+Enable the firmware node initialization only if it is Armv8R AArch64.
+Also, we increase the stack size to 1024 to fix the stack overflow issue
+when using the libfdt.
+
+Add -fno-builtin options to CFLAGS to avoid the issue that the 'memset'
+in common/lib.c conflicts with builtin 'memset' function. GCC version
+>= 10 will have an incorrect compilation without -fno-builtin;
+
+Issue-Id: SCM-3816
+Upstream-Status: Inappropriate [other]
+ Implementation pending further discussion
