Bits 16:31 - Major version
This preserves compatibility across newer and older version of the header.
The current version is defined as 0.1.
The current version is defined as 0.2.
- res3 is reserved for offset to any other additional fields. This makes the
header extendible in future. One example would be to accommodate ISA
extension for RISC-V in future. For current version, it is set to be zero.
- The "magic" field is deprecated as of version 0.2. In a future
release, it may be removed. This originally should have matched up
with the ARM64 header "magic" field, but unfortunately does not.
The "magic2" field replaces it, matching up with the ARM64 header.
- In current header, the flag field has only one field.
- In current header, the flags field has only one field.
Bit 0: Kernel endianness. 1 if BE, 0 if LE.
- Image size is mandatory for boot loader to load kernel image. Booting will
