+# to map the low globals page. We also need another 4MB to account for

+# For the moment, kaliber has a unique memory layout (monitor at the top

+# mandating 32MB alignment. Image base (i.e. __TEXT) must be 16KB
+# aligned since ld64 will link with 16KB alignment for ARM64.
+#
+# We currently offset by an additional 32MB in order to reclaim memory.
+# We need a dedicated virtual page for the low globals. Our bootloader
