#   Kernel 8955 Patches
# ============================================================================

# This file contains all the patches freeBOOT applies to the kernel. Patches
# for 1BL, CB, CD, and hypervisor were done with a different tool and are
# provided as files patches_<console>_base.bin. In order to yield a valid
# patches_<console>.bin file, the assembly of this file has to be appended to
# the corresponding patch_<console>_base.bin file. The included Makefile will
# automate this task.
#
# Patches for 1BL, CB, CD, hypervisor, and kernel all share the same format
# described herein. Since hypervisor and kernel patches are applied in the
# same run, hypervisor patches contained in patches_<console>_base.bin file
# are not terminated with 0xffffffff. It is therefore possible to add further
# hypervisor patches through this file. As seen by the patch engine, the
# hypervisor starts at address 0x00000000 and the kernel at address
# 0x00040000.

# Each sequence of patches starts with a target address and the number of
# patches in this sequence. The patches themselves follow directly. The target
# address must be aligned on a 4 byte boundary. All data in a patch sequence
# must be encoded in 32-bit big endian format.
#
# There can be an arbitrary number of patch sequences. The last patch sequence
# must be terminated with 0xffffffff.
