When reading data off a disk, sector values are based on the disk sector
length.
Within grub_util_fd_open_device(), the start of the partition was taken
directly from grub's partition information structure, which uses the
internal sector length (currently 512b), but never transformed to the
disk's sector length.
Subsequent calculations were all wrong for devices that have a diverging
sector length and the functions eventually skipped to the wrong stream
location, reading invalid data.

gentpl.py is python2/3-agnostic, but there's no way to cause it
to be run with any interpreter other than 'python', it's just
hard-coded into Makefile.common that way. Adjust that to use
AM_PATH_PYTHON (provided by automake) to find an interpreter
and run gentpl.py with that instead. This makes grub buildable
when `python` does not exist (but rather `python3` or `python2`
or `python2.7`, etc.) Minimum version is set to 2.6 as this is
the first version with `__future__.print_function` available.
Note, AM_PATH_PYTHON respects the PYTHON environment variable
and will treat its value as the *only* candidate for a valid
interpreter if it is set - when PYTHON is set, AM_PATH_PYTHON
will not try to find any alternative interpreter, it will only
check whether the interpreter set as the value of PYTHON meets
the requirements and use it if so or fail if not. This means
that when using grub's `autogen.sh`, as it too uses the value
of the PYTHON environment variable (and if it is not set, just
sets it to 'python') you cannot rely on AM_PATH_PYTHON
interpreter discovery. If your desired Python interpreter is
not just 'python', you must set the PYTHON environment variable,
e.g. 'PYTHON=/usr/local/bin/python3 ./autogen.sh'. The specified
interpreter will then be used both by autogen.sh itself and by
the autotools-driven build scripts.

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

Most 8" or 7" x86 Windows 10 tablets come with volume up/down buttons and

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

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
