21e4a6fa03 multiboot: disentangle multiboot and multiboot2.
Previously we had multiboot and multiboot2 declaring the same symbols.
This can potentially lead to aliasing and strange behaviours when e.g.
module instead of module2 is used with multiboot2.

f826330683 efi: change heap allocation type to GRUB_EFI_LOADER_CODE
With upcoming changes to EDK2, allocations of type EFI_LOADER_DATA may
not return regions with execute ability. Since modules are loaded onto
the heap, change the heap allocation type to GRUB_EFI_LOADER_CODE in
order to permit execution on systems with this feature enabled.

There is nothing ARM64 (or even ARM) specific about the efi fdt helper

4bc909bf89 Remove grub_efi_allocate_pages.
grub_efi_allocate_pages Essentially does 2 unrelated things:
* Allocate at fixed address.
* Allocate at any address.

To switch between 2 different functions it uses address == 0 as magic
value which is wrong as 0 is a perfectly valid fixed adress to allocate at.

Also delete some left-around #if 1/#else blocks in the affected
functions.

435fa75e01 * grub-core/fs/udf.c: Add support for UUID
Use same algorithm as in libblkid from util-linux v2.30.

1. Take first 16 bytes from UTF-8 encoded string of VolumeSetIdentifier
2. If all bytes are hexadecimal digits, convert to lowercase and use as UUID
3. If first 8 bytes are not all hexadecimal digits, convert those 8 bytes
   to their hexadecimal representation, resulting in 16 bytes for UUID
4. Otherwise, compose UUID from two parts:
   1. part: converted first 8 bytes (which are hexadecimal digits) to lowercase
   2. part: encoded following 4 bytes to their hexadecimal representation (16 bytes)

So UUID would always have 16 hexadecimal digits in lowercase variant.

According to UDF specification, first 16 Unicode characters of
VolumeSetIdentifier should be unique value and first 8 should be
hexadecimal characters.

In most cases all 16 characters are hexadecimal, but e.g. MS Windows
format.exe set only first 8 as hexadecimal and remaining as fixed
(non-unique) which violates specification.

734668238f Allow GRUB to mount ext2/3/4 filesystems that have the encryption feature.
On such a filesystem, inodes may have EXT4_ENCRYPT_FLAG set.
For a regular file, this means its contents are encrypted; for a
directory, this means the filenames in its directory entries are
encrypted; and for a symlink, this means its target is encrypted.  Since
GRUB cannot decrypt encrypted contents or filenames, just issue an error
if it would need to do so.  This is sufficient to allow unencrypted boot
files to co-exist with encrypted files elsewhere on the filesystem.

(Note that encrypted regular files and symlinks will not normally be
encountered outside an encrypted directory; however, it's possible via
hard links, so they still need to be handled.)

Tested by booting from an ext4 /boot partition on which I had run
'tune2fs -O encrypt'.  I also verified that the expected error messages
are printed when trying to access encrypted directories, files, and
symlinks from the GRUB command line.  Also ran 'sudo ./grub-fs-tester
ext4_encrypt'; note that this requires e2fsprogs v1.43+ and Linux v4.1+.

f8679cedff sparc64: Don't use devspec to determine the OBP path
Don't use devspec to determine the OBP path on SPARC hardware.  Within all
versions of Linux on SPARC, the devspec returns one of three values:
"none", "vnet-port", or "vdisk".  Unlike on PPC, none of these values
are useful in determining the OBP path.

Before this patch grub-ofpathname always returned the wrong value
for a virtual disk. For example:

% grub-ofpathname /dev/vdiskc2
vdisk/disk@2:b

After this patch it now returns the correct value:

% grub-ofpathname /dev/vdiskc2
/virtual-devices@100/channel-devices@200/disk@2:b

d33045ce7f util/grub.d/20_linux_xen.in: Add xen_boot command support for aarch64
This patch adds the support of xen_boot command for aarch64:
    xen_hypervisor
    xen_module
These two commands are only for aarch64, since it has its own protocol and
commands to boot xen hypervisor and Dom0, but not multiboot.

For other architectures, they are still using multiboot and module
commands.
