+# The GICv3 & ITS drivers allocation needs are:
+# - LPI prop table: global 1x64K aligned on 64K
+# - LPI pend table: for each redistributor/cpu 1x64K aligned on 64K
+# - Devices table: 128x4K aligned on 4K
+# - Interrupt Collections table: 1x4K aligned on 4K
+#
+# This makes 11x64K to permit all allocations to success.

+# Note, will need 64K HEAP_MEM per CPUs added.

+# This doesn't necessarily include the Interrupt Translation Table, which are

+#
+# To permit allocating 256 ITT tables of 32 ITEs, 13x64K HEAP_MEM is needed
