The 32-bit arm Linux kernel is built as a zImage, which self-decompresses
down to near start of RAM. In order for an initrd/initramfs to be
accessible, it needs to be placed within the first ~768MB of RAM.
The initrd loader built into the kernel EFI stub restricts this down to
512MB for simplicity - so enable the same restriction in grub.
For arm64, the requirement is within a 1GB aligned 32GB window also
covering the (runtime) kernel image. Since the EFI stub loader itself
will attempt to relocate to near start of RAM, force initrd to be loaded
completely within the first 32GB of RAM.

Most 8" or 7" x86 Windows 10 tablets come with volume up/down buttons and
a power-button. In their UEFI these are almost always mapped to arrow
up/down and enter.
Pressing the volume buttons (sometimes by accident) will stop the
menu countdown, but the power-button / "enter" key was not being recognized
as enter, so the user would be stuck at the grub menu.
The problem is that these tablets send scan_code 13 or 0x0d for the
power-button, which officialy maps to the F3 key. They also set
unicode_char to 0x0d.
This commit recognizes the special case of both scan_code and unicode_char
being set to 0x0d and treats this as an enter key press.

to choice a grub-menu entry using the buttons on the tablet.

The sparse inode metadata format became a mkfs.xfs default in
xfsprogs-4.16.0, and such filesystems are now rejected by grub as
containing an incompatible feature.
In essence, this feature allows xfs to allocate inodes into fragmented
freespace. (Without this feature, if xfs could not allocate contiguous
space for 64 new inodes, inode creation would fail.)
In practice, the disk format change is restricted to the inode btree,
which as far as I can tell is not used by grub. If all you're doing
today is parsing a directory, reading an inode number, and converting
that inode number to a disk location, then ignoring this feature
should be fine, so I've added it to XFS_SB_FEAT_INCOMPAT_SUPPORTED
I did some brief testing of this patch by hacking up the regression
tests to completely fragment freespace on the test xfs filesystem, and
then write a large-ish number of inodes to consume any existing
contiguous 64-inode chunk. This way any files the grub tests add and
traverse would be in such a fragmented inode allocation. Tests passed,
but I'm not sure how to cleanly integrate that into the test harness.

"F2FS (Flash-Friendly File System) is flash-friendly file system which was merged

The motive for F2FS was to build a file system that from the start, takes into
account the characteristics of NAND flash memory-based storage devices (such as
solid-state disks, eMMC, and SD cards).
F2FS was designed on a basis of a log-structured file system approach, which
remedies some known issues of the older log structured file systems, such as
the snowball effect of wandering trees and high cleaning overhead. In addition,
since a NAND-based storage device shows different characteristics according to
its internal geometry or flash memory management scheme (such as the Flash
Translation Layer or FTL), it supports various parameters not only for
configuring on-disk layout, but also for selecting allocation and cleaning
algorithm.", quote by https://en.wikipedia.org/wiki/F2FS.

This patch fixes the build error by cleaning up the ambiguity of placing

grub_gpt_part_type", the aligned attribute seems to be superfluous, and also
has to be packed, to ensure the structure is bit-to-bit mapped to the format

While many classes of data can be provided by early images, the

There are two environment variables provided for declaring the early

* GRUB_EARLY_INITRD_LINUX_STOCK is for the distribution declare
images that are provided by the distribution or installed packages.
If undeclared, this will default to a set of common microcode image
names.
* GRUB_EARLY_INITRD_LINUX_CUSTOM is for user created images. User
images will be loaded after the stock images.
These separate configurations allow the distribution and user to
declare different image sets without clobbering each other.
This also makes a minor update to ensure that UUID partition labels
