[PATCH v1 0/4] Allow loading a no MMU kernel

From: Alistair Francis
Subject: [PATCH v1 0/4] Allow loading a no MMU kernel
Date: Fri, 2 Oct 2020 08:31:02 -0700

This series allows loading a noMMU kernel using the -kernel option.
Currently if using -kernel QEMU assumes you also have firmware and loads
the kernel at a hardcoded offset. This series changes that so we only
load the kernel at an offset if a firmware (-bios) was loaded.

This series also adds a function to check if the CPU is 32-bit. This is
a step towards running 32-bit and 64-bit CPUs on the 64-bit RISC-V build
by using run time checks instead of compile time checks. We also allow
the user to sepcify a CPU for the sifive_u machine.

Alistair Francis (4):
  hw/riscv: sifive_u: Allow specifying the CPU
  hw/riscv: Return the end address of the loaded firmware
  hw/riscv: Add a riscv_is_32_bit() function
  hw/riscv: Load the kernel after the firmware
