# 1.3 13-Sep-2019 manu

Add multiboot 2 support to x86 bootloaders

multiboot 2 is required to boot Xen on an EFI system.
This also require a kernel patch for properly discovering
the ACPI RSDP, which is available after 20190912, in
src/sys/arch/x86/acpi/acpi_machdep.c 1.26-1.28

There are a few missing bit in this multiboot 2 implementation
(which are unused by Xen):
- Header tags Address, Freambuffer, and Relocatable are ignored
- Tags APM and Network are not provided
- Tags ACPI old and ACP new are only provided for ACPI boot
- Tag boot device does not provides the subpart (BSD disklabel partition)

Notes:
- multiboot2 is disabled in dosboot, otherwise the binary
gets too big and build fails.
- in src/sys/arch/i386/stand/efiboot, consinit() is renamed
as efi_consinit() to avoid prototype conflicts in src/sys/sys/systm.h

# 1.1 11-Oct-2008 joerg

branches: 1.1.2; 1.1.10; 1.1.16; 1.1.44; 1.1.64; 1.1.68;
Add "multiboot" command to boot multiboot compliant kernels like Xen.
Patch provided by Robert Swindell with fixes for the command line
parsing and addition of passing module options from me. The kernel now
always gets the full string for modules like for the command line,
everything before the first space/tab is the path name of the module.
