# 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
#
# 0xfffffff000000000 (32MB range for low globals)
# 0xfffffff002000000 (32MB range to allow for large page physical slide)
# 0xfffffff004000000 (16KB range to reserve the first available page)
# 0xfffffff004004000 (48MB range for kexts)
# 0xfffffff007004000 (Start of xnu proper).
