478e54b738 grub-reboot: Warn when "for the next boot only" promise cannot be kept
The "for the next boot only" property of grub-reboot is dependent upon
GRUB being able to clear the next_entry variable in the environment
block. However, GRUB cannot write to devices using the diskfilter
and lvm abstractions.

d62cafcf35 ahci: Increase time-out from 10 s to 32 s
This is a cryptographically signed message in MIME format.

Date: Thu, 9 Aug 2018 07:27:35 +0200

Currently, the GRUB payload for coreboot does not detect the Western
Digital hard disk WDC WD20EARS-60M AB51 connected to the ASRock E350M1,
as that takes over ten seconds to spin up.

```
disk/ahci.c:533: port 0, err: 0
disk/ahci.c:539: port 0, err: 0
disk/ahci.c:543: port 0, err: 0
disk/ahci.c:549: port 0, offset: 120, tfd:80, CMD: 6016
disk/ahci.c:552: port 0, err: 0
disk/ahci.c:563: port 0, offset: 120, tfd:80, CMD: 6016
disk/ahci.c:566: port: 0, err: 0
disk/ahci.c:593: port 0 is busy
disk/ahci.c:621: cleaning up failed devs
```

GRUB detects the drive, when either unloading the module *ahci*, and
then loading it again, or when doing a warm reset.

As the ten second time-out is too short, increase it to 32 seconds,
used by SeaBIOS. which detects the drive successfully.

The AHCI driver in libpayload uses 30 seconds, and that time-out was
added in commit 354066e1 (libpayload: ahci: Increase timeout for
signature reading) with the description below.

> We can't read the drives signature before it's ready, i.e. spun up.
> So set the timeout to the standard 30s. Also put a notice on the
> console, so the user knows why the signature reading failed.

a2f26adfef efi: Restrict arm/arm64 linux loader initrd placement
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.

886edba877 i386/linux: Add support for ext_lfb_base
The EFI Graphics Output Protocol can return a 64-bit
linear frame buffer address in some firmware/BIOS
implementations. We currently only store the lower
32-bits in the lfb_base. This will eventually be
passed to Linux kernel and the efifb driver will
incorrectly interpret the framebuffer address as
32-bit address.

The Linux kernel has already added support to handle
64-bit linear framebuffer address in the efifb driver
since quite some time now.

This patch adds the support for 64-bit linear frame
buffer address in GRUB to address the above mentioned
scenario.

edece25a77 efi/console: Fix the "enter" key not working on x86 tablets
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.

This fixes things getting stuck at the grub-menu and allows the user
to choice a grub-menu entry using the buttons on the tablet.

347210a5d5 efi/fdt: Set address/size cells to 2 for empty tree
When booting an arm* system on UEFI with an empty device tree (currently
only when hardware description comes from ACPI), we don't currently set

Set both of these properties, to 2 cells (64 bits), to resolve issues

This change corresponds with linux kernel commit ae8a442dfdc4
("efi/libstub/arm*: Set default address and size cells values for an empty dtb")
and ensures booting through grub does not behave differently from booting
the stub loader directly.

cda0a857dd xfs: Accept filesystem with sparse inodes
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.

71f9e4ac44 fs: Add F2FS support
"F2FS (Flash-Friendly File System) is flash-friendly file system which was merged
into Linux kernel v3.8 in 2013.

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.

When building with GCC 8, there are several errors regarding packed-not-aligned.

./include/grub/gpt_partition.h:79:1: error: alignment 1 of ‘struct grub_gpt_partentry’ is less than 8 [-Werror=packed-not-aligned]

This patch fixes the build error by cleaning up the ambiguity of placing
aligned structure in a packed one. In "struct grub_btrfs_time" and "struct
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
laid on disk. I think we could blame to copy and paste error here for the
mistake. In "struct efi_variable", we have to use grub_efi_packed_guid_t, as
the name suggests. :)

a537d65018 efi/uga: Fix PCIe LER when GRUB2 accesses non-enabled MMIO data from VGA
A GPU inserted into a PCIe I/O slot disappears during system startup.
The problem centers around GRUB and a specific VGA init function in
efi_uga.c. This causes an LER (Link Error Recorvery) because the MMIO
memory has not been enabled before attempting access.

The fix is to add the same coding used in other VGA drivers, specifically
to add a check to insure that it is indeed a VGA controller. And then
enable the MMIO address space with the specific bits.

c225298038 chainloader: patch in BPB's sectors_per_track and num_heads
These fields must reflect the ROM-BIOS's geometry for CHS-based
loaders to correctly load their next stage. Most loaders do not
query the ROM-BIOS (Int13.08), relying on the BPB fields to hold
the correct values already.

Tested with lDebug booted in qemu via grub2's
FreeDOS direct loading support, refer to
https://bitbucket.org/ecm/ldosboot + https://bitbucket.org/ecm/ldebug
(For this test, lDebug's iniload.asm must be assembled with
-D_QUERY_GEOMETRY=0 to leave the BPB values provided by grub.)

a698240df0 grub-mkconfig/10_linux: Support multiple early initrd images
Add support for multiple, shared, early initrd images. These early
images will be loaded in the order declared, and all will be loaded
before the initrd image.

While many classes of data can be provided by early images, the
immediate use case would be for distributions to provide CPU
microcode to mitigate the Meltdown and Spectre vulnerabilities.

There are two environment variables provided for declaring the early
images.

* 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
stay disabled when no initrd image is found, even if early images are
present.

This is a continuation of a previous patch published by Christian
Hesse in 2016:
