[Buildroot] [PATCH v2 0/4] board/visionfive2: fix boot issue and bump Linux/U-Boot/OpenSBI versions

[Fengwei Tan]

Hello all,

This series fixes a boot issue on the StarFive VisionFive 2 and bumps
the Linux, U-Boot, and OpenSBI versions.

The main changes in this series:

- Add the missing 'rootwait' parameter to prevent kernel panics caused
  by asynchronous MMC cards detection.
- Remove the SPL and U-Boot partitions from the SD card image, following
  the deprecation of SD card boot mode in U-Boot since v2025.10.
- Add support for VisionFive 2 v1.2a by enabling U-Boot to dynamically
  decide which FDT to load.

I have tested this series on a VisionFive 2 v1.2a board, and the system
boots successfully [1].

---
Changes in v2:
- Patch 2: Adjust indentation of the commands in the commit message
- Patch 3: Pin the U-Boot documentation link to v2026.07
- Patch 4: Reword the commit message to clarify that U-Boot sets
  $fdtfile automatically only when it is not already set.
- Link to v1: https://patch.msgid.link/SY8P300MB00419E6035B2DD54F72006D3B5872@SY8P300MB0041.AUSP300.PROD.OUTLOOK.COM

[Buildroot] [PATCH v2 1/4] board/visionfive2: add rootwait to kernel command line

[Fengwei Tan]

MMC cards are detected asynchronously, so the root device may not be
available when the kernel tries to mount the root filesystem.

Add rootwait to wait for the root device and avoid a kernel panic.

[Buildroot] [PATCH v2 2/4] board/visionfive2: remove non-upstream Linux config options

[Fengwei Tan]

Remove vendor-specific config options from linux_defconfig as they are
not present in the upstream kernel.

Regenerate the defconfig by running:

  make visionfive2_defconfig
  make linux-menuconfig
  # Save and exit without making any changes.
  make linux-update-defconfig

[Buildroot] [PATCH v2 3/4] configs/visionfive2: bump Linux to 6.18.51, U-Boot to 2026.07, and OpenSBI to 1.8.1

[Fengwei Tan]

Migrate and clean up removed kernel config options during the upgrade.

Drop uboot and spl partitions from the SD card genimage configuration,
as U-Boot has deprecated the SD card and eMMC boot modes since
v2025.10 [1]. Update the rootfs block device in the kernel command line
accordingly.

Update readme.txt to reflect the new boot flow and instructions.

[Buildroot] [PATCH v2 4/4] board/visionfive2, configs/visionfive2: add support for v1.2a board

[Fengwei Tan]

There are two revisions of the VisionFive 2: v1.2a and v1.3b. The main
difference between them is that v1.2a has one Gigabit Ethernet port and
one Fast Ethernet port, while v1.3b has two Gigabit Ethernet ports.

Unless explicitly set, U-Boot automatically sets $fdtfile based on the
EEPROM product data during initialization, enabling <fdtdir>/<fdtfile>
to be loaded via extlinux.conf.

Additionally, since $fdtfile contains the directory name, preserve the
directory structure of the DTBs when copying them to the target
directory.
