LoongArch is a new Loongson 3A5000 CPU instruction set, you can read
documents[1] or visit the development community[2] to get more information.

[1]: https://loongson.github.io/LoongArch-Documentation/README-EN.html
[2]: https://github.com/loongson

This patch series will add the basic support for LoongArch architecture, it can
compile on LoongArch and display the GRUB UI.

The full LoongArch patch has two parts, this is the first part.

The second part needs to wait for the LoadFile2 patch to be merged upstream first.
See: https://github.com/loongarch64/grub/tree/dev/patchwork/efi

Please review the patches, thank you.

v1->v2:
- rebase on the last commit.
- fix some errors.
- change the year to 2022 for the new files.

v2->v3:
- based on the last commit.
- add a comment to setjmp.S
- complete LoongArch support for grub-mkrescue

v3->v4:
- based on the last commit.

v4->v5:
- Fix make distcheck failed.
- Add tests support.
- based on the last commit.

v5->v6:
- Support new relocation types.
- Fix some test cases.

Here is the test results:

============================================================================
Testsuite summary for GRUB 2.11
============================================================================
# TOTAL: 82
# PASS:  56
# SKIP:  8
# XFAIL: 0
# FAIL:  2
# XPASS: 0
# ERROR: 16
============================================================================
See ./test-suite.log
Please report to bug-grub@gnu.org
============================================================================


The full test log is here: https://github.com/loongarch64/grub/files/9239702/test-suite.log

There are two test cases failed:

FAIL: squashfs_test
FAIL: grub_func_test

The squashfs_test failed because FSTIME does not match:

Device proc: Filesystem type procfs - Sector size 512B - Total size 0KiB
Device loop0: Filesystem type squash4 - Last modification time 2022-08-02 06:21:25 Tuesday - Sector size 512B - Total size 10680KiB
Device host: Filesystem type hostfs - Sector size 512B - Total size 0KiB

FSTIME FAIL
2022-08-02 14:21:25
Device loop0: Filesystem type squash4 - Last modification time 2022-08-02 06:21:25 Tuesday - Sector size 512B - Total size 10680KiB
FAIL squashfs_test (exit status: 1)

This failure can be ignored because my timezone is UTC+8:

The firmware should not be specified with an absolute path because that
effectively disables searching for the firmware and make the -L option
useless. So I believe it should just be "-bios edk2-loongarch64-code.fd".

> +	disk="device virtio-blk-pci,drive=hd1 -drive if=none,id=hd1,file="

I realize now that I was confused by the hd1 here. This is just an identifier
and has no other meaning. In fact, this disk gets set as the first disk
in QEMU. Looking at the code again, the extra disk handling code really needs
to be updated and reworked. I think this line is fine for now.

The hd0 here is also misleading, as it will get set as the last of a series
of disks, which in the case of the partmap_test will the the second disk.
I know this is essentially copied from the if block above it, but instead
of using hd0, how about using "grubdev", which seems a more accurate name.

Also, I'm wondering why use "virtio-blk-pci" instead of "virtio-blk-device"
as ARM does above? I this just the more preferred way to do this with QEMU
now, or is there an important functional difference?

qemu-system-loongarch64 does not support 'virtio-blk-device'. If it is 
used, I will get an error:

qemu-system-loongarch64: -device virtio-blk-device,drive=grubdev: No 
'virtio-bus' bus found for device 'virtio-blk-device'

So, I can only use `virtio-blk-pci`.
