Field name: min_alignment
Type: read (reloc)
Offset/size: 0x235/1
Protocol: 2.10+
This field, if nonzero, indicates as a power of two the minimum
alignment required, as opposed to preferred, by the kernel to boot.
If a boot loader makes use of this field, it should update the
kernel_alignment field with the alignment unit desired; typically:
kernel_alignment = 1 << min_alignment
There may be a considerable performance cost with an excessively
misaligned kernel. Therefore, a loader should typically try each
power-of-two alignment from kernel_alignment down to this alignment.

Field name: init_size

Offset/size: 0x25c/4
This field indicates the amount of linear contiguous memory starting
at the kernel runtime start address that the kernel needs before it
is capable of examining its memory map. This is not the same thing
as the total amount of memory the kernel needs to boot, but it can
be used by a relocating boot loader to help select a safe load
address for the kernel.
The kernel runtime start address is determined by the following algorithm:
if (relocatable_kernel)
runtime_start = align_up(load_address, kernel_alignment)
