[isar-cip-core][PATCH v4 0/8] Add swupdate support for riscv64

[isar-cip-core][PATCH v4 0/8] Add swupdate support for riscv64

[Felix Moessbauer]

Changes since v3:

- rebased onto next
- add patch to clarify situation around watchdog on arm*
- u-boot: remove irrelevant patch around FPU

Changes since v2:

The v2 adds the required infrastructure to test the swupdate support
in qemu-riscv64. This includes the following additions:

- update of cip kernel config for qemu-riscv64 machine (for non swu case)
- refactoring of u-boot deploy logic as preparation for next patches
- u-boot + opensbi firmware for qemu
- addition of linux 6.1 mainline kernel to support EFI boot of riscv64
  in qemu
- extension of start-qemu script to boot riscv64 with swupdate support

Changes since v1:

- rebased onto next
- ebg: fix changelog version (no <orig-version>)
- add swupdate support for qemu-riscv64

Please note: The EBG support in cip-core needs a major rework to be in
sync with the upstream debian package names. Currently, sid cannot be
updated to a more recent revision, as this breaks the build (multiple
packages with different names provide the same binary).

Best regards,

[isar-cip-core][PATCH v4 1/8] make reason for disabling wdog on arm more precise

[Felix Moessbauer]

This patch reworks the comment describing why the watchdog is disabled
for arm and arm64. Previously it was stated that the watchdog is armed
by u-boot, but technically it simply never was supported to have a
watchdog on these platforms when using the start-qemu script.

[isar-cip-core][PATCH v4 2/8] fix efibootguard for riscv64

[Felix Moessbauer]

This commit backports an upstream patch for efibootguard that
fixes the riscv64 install location. As it is not yet in an
EBG release, we add it as a patch here. No internal logic of EBG is
changed, hence no dedicated release is needed.

[isar-cip-core][PATCH v4 4/8] add opensbi with u-boot payload for riscv64

[Felix Moessbauer]

This patch adds the opensbi firmware with u-boot payload (smode) for the
qemu-riscv64 machine. Using that, the generated riscv64 images can be
booted on qemu.

+The following description is copied from the equivalent patch for the

+
+>From version 2.38, binutils default to ISA spec version 20191213. This
+means that the csr read/write (csrr*/csrw*) instructions and fence.i
+instruction has separated from the `I` extension, become two standalone
+extensions: Zicsr and Zifencei. As the kernel uses those instruction,
+this causes the following build failure:

[isar-cip-core][PATCH v4 5/8] enhance qemu-riscv64 machine to be testable

[Felix Moessbauer]

This patch enhances the qemu-riscv64 machine by adding a reference to
u-boot. Further, we now use the qemu_riscv64 defconfig from
cip-kernel-config.

[isar-cip-core][PATCH v4 6/8] add linux 6.1 mainline kernel

[Felix Moessbauer]

This patch adds the vanilla 6.1 linux kernel for testing and for boards
which need a more recent kernel than what CIP can offer.
The kernel can be selected from the menu, similar to the other kernels.
As defconfig, we always use the kernels internal configuration, because
there is no cip-kernel-config for that version yet. In addition, the
squashfs knob is selected to support the swupdate pattern without any
modifications.

[isar-cip-core][PATCH v4 7/8] add swupdate support for qemu-riscv64

[Felix Moessbauer]

This patch enables the swupdate KConfig entry for the qemu-riscv64
board. For that, we also duplicate the qemu-arm64-efibootguard.wks
template for qemu-riscv64. As this is the first riscv64 board, we do not
symlink but create a copy.

[Felix Moessbauer]

This patch adds support to run swupdate images for RISC-V64 on qemu. As
firmware, we use OpenSBI with u-boot payload in s-mode.
