[PATCH v6 0/6] riscv: Switch to use generic platform fw_dynamic type opensbi bios images

[Bin Meng]

From: Bin Meng <bin.meng@windriver.com>

The RISC-V generic platform is a flattened device tree (FDT) based
platform where all platform specific functionality is provided based
on FDT passed by previous booting stage. The support was added in
the upstream OpenSBI v0.8 release recently.

This series updates QEMU to switch to use generic platform of opensbi
bios images. With the recent fw_dynamic image support, let's replace
the fw_jump images with fw_dynamic ones too.

The patch emails do not contain binary bits, please grab all updates
at https://github.com/lbmeng/qemu.git bios branch.

Note:

1. To test 32-bit Linux kernel on QEMU 'sifive_u' 32-bit machine,
the following patch is needed:

2. To test 64-bit Linux 5.3 kernel on QEMU 'virt' or 'sifive_u' 64-bit
machines, the following commit should be cherry-picked to 5.3:

    riscv: Fix memblock reservation for device tree blob

Linux 5.4 or above already contains this commit/fix.

Changes in v6:
- Rebased on https://github.com/alistair23/qemu/commits/riscv-to-apply.next
- Add information about Linux kernel tested
- Squash the Makefile ELF changes into patch 5

Changes in v5:
- Include the generic fw_dynamic.bin in the Makefile for `make install` 
bisection

Changes in v4:
- Remove old binaries in the Makefile for `make install` bisection

Changes in v3:
- Change fw_jump to fw_dynamic in the make rules
- Change to fw_dynamic.bin for virt & sifive_u
- Change to fw_dynamic.elf for Spike
- Generate fw_dynamic images in the artifacts

Changes in v2:
- new patch: configure: Create symbolic links for pc-bios/*.elf files
- Upgrade OpenSBI to v0.8 release
- Copy the ELF images too in the make rules
- Include ELF images in the artifacts
