> Subject: [PATCH] riscv: qemu: spl: Fix booting Linux kernel with OpenSBI 1.0+
>
> Since OpenSBI commit bf3ef53bb7f5 ("firmware: Enable FW_PIC by default"),
> OpenSBI runs directly at the load address without any code movement.
> This causes the SPL version of QEMU 'virt' U-Boot does not boot Linux kernel
> anymore. In that case, OpenSBI is loaded and runs at 0x81000000, and it
> creates a 512KiB PMP window from that address. When booting the Linux kernel,
> moving kernel to its linking address 0x80200000 overlaps the PMP window, and
> a PMP access failure is raised.
>
> Update SPL_OPENSBI_LOAD_ADDR to load OpenSBI to a safe address.
