+ xilpm: versal: server: Fix bug in AIE2 zeroization
+
+ There is a bug in AIE2 zeriozation function when polling for memory
+ zeroization complete. Currently the entire memory register is being
+ checked against zero but instead we need to check the bits specific
+ to the memory tiles. This patch updates the zeroization check by
+ adding a mask so that only the desired bits are checked for zero.
