[PATCH v4 0/6] Add BSP for StarFiveTech VisionFive2 Risc-V board

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

Changes since v3:

- rebased onto next
- drop "u-boot: make KCFLAGS and HOSTCFLAGS configurable"
- opensbi: update version
- u-boot
  - update which makes patches obsolete
  - support to compile without cross
  - simplify build dependencies
  - remove KCFLAGS injection
- spl_tool: replace with OSS version from StarFive
- linux: update which makes patches obsolete

Changes since v2:

- rebased onto next
- rework u-boot customization (p1)
- update opensbi
- update kernel

Changes since v1:

- rebased onto next (including bitbake 2.0 migration)
- exclude opensbi memory range in u-boot DT
- use upstream OpenSBI version (instead of StarFive version)

This series adds a new machine "starfive-visionfive2" which is a
Risc-V board based on the JH7110 SoC. The BSP is modeled based on the
buildroot SDK [1], but without any proprietary imaging components.

Further, we implement the fit + efi boot toolchain, instead of the
proposed ubootenv + fit version. This also requires that we embed the
board's linux device tree into the fit, as memory and reserved-memory
nodes are resolved via the efi API (implemented by u-boot) instead of
resolving them via the DT in Linux.

As the JH7110 SoC has no usable upstream support yet, we directly
build the 5.15 based kernel from the SDK, instead of porting patches
on top of the standard Linux. Distro kernels are also not supported.
