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

[Felix Moessbauer <felix.moessbauer@siemens.com>]

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).
