The GRUB configuration files layout on EFI platforms isn't consistent with
other non-EFI platforms (e.g: legacy BIOS x86 and Open Firmware ppc64le).
On platforms using EFI, the GRUB config file (grub.cfg) and environment
variables block (grubenv) are stored in the EFI System Partition (ESP),
while for non-EFI platforms these are stored in the boot partition (or
/boot directory if not boot partition is used).
The reason for this is that the path where the GRUB bootloader searches
for its configuration file varies depending on the firmware interface.
For EFI the GRUB binary is located in the ESP and it expects to find its
config file in that location as well. But this creates the mentioned
inconsistency, because the GRUB configuration file has to be stored in
/boot/efi/EFI/fedora/grub.cfg while for non-EFI platforms it has to be
stored in /boot/grub2/grub.cfg.
To allow all platforms to have the GRUB config file in the same location,
only a minimal config file could be stored in the ESP and this will load
the one that is stored in /boot/grub2.

GRUB uses -march=i386 to build the x86 BIOS code but recent changes in the
default %{optflags} enabled the -fcf-protection flag that's not compatible
with pre-i686 CPUs.
This led to a build error in the grub2 package. To avoid this failure and
let the package to build again, remove the -fcf-protection flag for now.

Users can unintentionally remove the grub2 packages and break their system
by deleting the bootloader. To prevent this mark them as protected by DNF.

The /boot/grub2/grubenv file is not installed by the grub2 packages but
is either a symbolic link created on %install or a regular file created
by Anaconda during installation.
This is causing the tps-rpmtest to fail in some architectures since the
file attributes don't match what's expected by the package. Because is
a special file, make verification to ignore the size, mode, checksum
and mtime attributes.

The Default Boot Behavior for EFI if no BootOrder and Boot#### variables
are found is to look for an ESP and start \EFI\BOOT\BOOT{$arch}.efi.
This is usually fallback.efi installed by the shim package, but since shim
isn't used on armv7, there's no \EFI\BOOT\BOOTARM.EFI installed in the ESP.
So install GRUB as \EFI\BOOT\BOOTARM.EFI for armv7 so there is a default
EFI binary to be started.

Since GRUB 2.04 there is support for TPM measurements in a tpm module that
uses the verifiers framework. So this is used now instead of the previous
downstream patches that we were carrying.
But we forgot to enable this module when rebasing to 2.04 which leads to
GRUB no longer measuring the kernel, initrd and command line parameters.
One side effect of using the verifiers framework is that if measurements
fail, GRUB won't be able to open the files since the errors from the tpm
module are propagated. This means that a firmware with a buggy tpm support
will prevent the machine to boot, which was not the case with the previous
downstream patches. Don't propagate the measurement errors to prevent this.

- drop deprecated groups from the macros file, already gone from main spec.
- don't ship arch specific bits in tools-extra that are already special cased in tools
- move grub2-glue-efi to tools-efi, it's Mac specific and there's othe Mac efi tools there
- drop tools-extra dep for efi binaries, all in tools-efi and anaconda deals with that
- put grub2-install man page in the right package with the util
- other minor cleanups
This change updates grub to the 2.04 release. The new release changed how
grub is built, so the bootstrap and bootstrap.conf files have to be added
to the dist-git. Also, the gitignore file changed so it has to be updated.
Since the patches have been forward ported to 2.04, there's no need for a
logic to maintain a patch with the delta between the release and the grub
master branch. So the release-to-master.patch is dropped and no longer is
updated by the do-rebase script.
Also since gnulib isn't part of the grub repository anymore and cloned by
the boostrap tool, a gnulib tarball is included as other source file and
copied before calling the bootstrap tool. That way grub can be built even
in builders that only have access to the sources lookaside cache.

The rpm-build's "debugedit" program will silently corrupt .debug_macro
strings when a binary is compiled with -g3. Later in the build phase,
gdb-add-index is invoked to extract the DWARF index from the binary,
and GDB will segfault because dwarf2read.c:parse_definition_macro's
'body' variable is NULL.

rpmdiff noticed the following:

Hardened: grub2-ofpathname: FAIL: Gaps were detected in the annobin coverage. Run with -v to list.

Hardened: grub2-ofpathname: FAIL: Not linked as a position independent executable (ie need to add '-pie' to link command line).
' on ppc64le
This is because while we made the CFLAGS get some new options, LDFLAGS never
got the same treatement, and we disabled %{_hardened_build} to avoid getting
its options in the TARGET_{C,LD}FLAGS variables.
This patch duplicates the infrastructure for {HOST,TARGET}_CFLAGS into
{HOST,TARGET}_LDFLAGS, and adds the %{_hardening_ldflags} and
%{_hardening_cflags} to both HOST_{C,LD}FLAGS.
Additionally, it fixes the CPPFLAGS definitions, since rpm doesn't define any
CPPFLAGS at all, and makes the -I$(pwd) be there exclusively, not on CFLAGS as
well, since they're always used in concert.

os-prober 1.75 dropped all the code for handling device mapper
directly in favor of only supporting the use of grub2-mount.
Thus, we now need grub2-mount to be built and packaged so that
os-prober can depend on it. We ship it in the grub2-tools-minimal
package to avoid creating a dependency loop between grub2-tools and
os-prober.

The grub2-efi package create a /boot/grub2/grubenv symlink that points to
/boot/efi/EFI/fedora/grubenv that's where the real grubenv file is looked
up by GRUB on an EFI installation.
But currently if the grub2-efi is installed on a legacy BIOS install, it
will overwrite an existing /boot/grub2/grubenv file with a broken symlink.
So mark it as %config(noreplace) to avoid loosing an existing grubenv.

- Limit grub_malloc() on x86_64 to < 31bit addresses, as some devices seem to
have a colossally broken storage controller (or UEFI driver) that can't do
DMA to higher memory addresses, but fails silently.
Resolves: rhbz#1626844 (possibly really resolving it this time.)
- Also integrate Hans's attempt to fix the related error from -54, but do it
the other way around: try the low addresses first and *then* the high one if
the allocation fails. This way we'll get low regions by default, and if
kernel/initramfs don't fit anywhere, it'll try the higher addresses.
