[U-Boot] RISC-V: Crashes with OpenSBI+U-Boot on the qemu "virt" machine
Hello,
I'm currently testing the U-Boot patch for adding booti support on the RISC-V architecture and the corresponding kernel patch on a qemu riscv64 "virt" machine with OpenSBI. While performing the tests, I have found two probably unrelated issues in U-Boot and OpenSBI, though I'm unsure whether the actual source of the problem is on the OpenSBI or on the U-Boot side, therefore I'm sending this to both the U-Boot and the OpenSBI lists.
a) U-Boot crashes if the system has 2GB of RAM or more and uses OpenSBI as the first stage:

The same U-Boot image works fine when loaded from BBL, even with more than 2GB of RAM, so the source of the issue is probably either somewhere in OpenSBI or in the interaction between OpenSBI and U-Boot.
b) The second issue is a problem with running on an SMP system, i.e. if qemu-system-riscv64 is called with "-smp 2". U-Boot commit d0a8fd3e4d2a5ab19b8f2d27d40dacb4942ba5a4 has enabled SMP for the qemu riscv64 "virt" platform, but when booting a kernel from U-Boot on a 2-CPU "virt" machine, the kernel boots, but the system hangs as soon as the kernel executes init. This happens both when U-Boot uses OpenSBI as its first stage as well as when U-Boot uses BBL as its first stage. If one loads a kernel directly from BBL instead without U-Boot in between, the same 2-CPU configuration works without problems and the kernel uses both CPUs.

Hi Karsten,
First of all, the 2GB case where U-Boot crashes shows that U-Boot is trying to access memory close to 0x80000000 where OpenSBI firmware is running hence it gets ACCESS fault. The OpenSBI protects firmware using PMP configuration whereas BBL does not. In fact, it is very easy to corrupt BBL from S-mode.
In fact, the U-Boot crashes with OpenSBI implies that issue in U-Boot which OpenSBI is helping us detect by injecting ACCESS fault to S-mode.
I tries vanilla U-Boot-2019.07-rc1 (without booti support) and OpenSBI at commit f9643f34. It worked fine for me. Here's the boot log:

Hi Karsten,
I tried again with image header changes applied to u-boot and Linux kernel but still not able to reproduce the issues.
Either you might have more local changes or debian toolchain is causing issue for u-boot.
Here are the logs....
