At present the 32-bit OpenSBI generic firmware image does not boot on
Spike, only 64-bit image can. This is due to the HTIF emulation does
not implement the proxy syscall interface which is required for the
32-bit HTIF console output.
An OpenSBI bug fix [1] is also needed when booting the plain binary image.
With this series plus the above OpenSBI fix, both 32-bit OpenSBI BIN & ELF
images can boot on QEMU 'spike' machine.

Changes in v2:
- fix 2 typos in the commit message
- initialize firmware_end_addr to memmap[SPIKE_DRAM].base
- rework the htif_custom_base detection logic
Bin Meng (10):
hw/char: riscv_htif: Avoid using magic numbers
hw/char: riscv_htif: Drop {to,from}host_size in HTIFState
hw/char: riscv_htif: Drop useless assignment of memory region
hw/char: riscv_htif: Use conventional 's' for HTIFState
hw/char: riscv_htif: Move registers from CPUArchState to HTIFState
hw/char: riscv_htif: Remove forward declarations for non-existent
variables
hw/char: riscv_htif: Support console output via proxy syscall
hw/riscv: spike: Remove the out-of-date comments
hw/riscv/boot.c: Introduce riscv_find_firmware()
hw/riscv: spike: Decouple create_fdt() dependency to ELF loading
Daniel Henrique Barboza (2):
hw/riscv/boot.c: make riscv_find_firmware() static
hw/riscv/boot.c: introduce riscv_default_firmware_name()
