+# Offset image base by page to have iBoot load kernel TEXT correctly.
+# First page is used for various purposes : sleep token, reset vector.
+# We also need a 32MB offset, as this is the minimum block mapping size
+# for a 16KB page runtime, and we wish to use the first virtual block
+# to map the low globals page. We also need another 4MB to account for
+# the address space reserved by L4 (because the reservation is not a
+# multiple of the block size in alignment/length, we will implictly map
+# it with our block mapping, and we therefore must reflect that the
+# first 4MB of the block mapping for xnu do not belong to xnu).
+# For the moment, kaliber has a unique memory layout (monitor at the top
+# of memory). Support this by breaking 16KB on other platforms and
+# 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
+# may have a significant chunk of memory (up to an L2 entry in size)
+# that lies before the kernel. The addition 32MB of virtual padding
+# ensures that we have enough virtual address space to map all of that
+# memory as part of the V-to-P mapping.
+# 23355738 - put __PRELINK_TEXT first. We reserve enough room
+# for 0x0000000003000000 = 48MB of kexts
