/*
 * boot_info_offsets.h — fixed byte offsets of BootInfo fields
 *
 * Read by kernel_entry.S (assembly) AND verified by _Static_assert in
 * uefi_loader.c.  Both uses share this header; only #define directives
 * are used so the file is valid for the C preprocessor AND the GAS
 * preprocessor (which runs on .S files compiled via CC).
 *
 * If you change the BootInfo struct layout in uefi.h, update the
 * constants below AND re-check the _Static_asserts (search BOOT_INFO_OFFSETS).
 *
 * BootInfo layout (64-bit, natural alignment):
