The main goal of this patch series is to pass initrd position to
secondary kernel. To makes code clear, patch 2/3 introduce a new
function to handle fdt related operations.
Without these two patches, kexec failed to work on arm.
Change from v1:
- Remove #include "libfdt_internal.h" since it is for internal use
for libfdt.
Change from v2:
- Split into two logically independent patches.
- Compute memory consumption more accurate.
Change from v3:
- Introduces helpers in libfdt for memory usage computation.
Wang Nan (3):
kexec: introduce helpers for computing dtb size
kexec: introduce setup_dtb_prop to make code clear
kexec: pass initrd position by dtb
