MTRR functionality is available only on x86, so this driver cannot be compiled
on other architectures. Fix this with preprocessor directives.

The X86EMU_RAW_IO mode can be used only on x86, so don't select this option
always, and allow correct compilation of BIOSEMU on other architectures too.

This allows selecting BIOSEMU in "make menuconfig", and provides one-line

for all three configuration parameters in bios_emulator/Kconfig.

The bios_emulator driver cannot be compiled for RISC-V because the x86emu.h
header file doesn't define the comment symbol ("#") for the assembler.
With this patch, use the same symbol as for e.g. x86.

When compiling for riscv64, a bunch of warning is produced for the file
drivers/bios_emulator/besys.c. This patch fixes a portion of those warnings,
caused by incorrect first argument to pci_{read,write}_config_* functions.

If BIOSEMU is compiled for RISC-V (SiFive Unmatched board) and the function
dm_pci_run_vga_bios() is executed, U-Boot stops with error message saying
that the SPL malloc pool is too small. So increase the default pool size
when both BIOSEMU and RISCV parameters are set.

Hi all,
When trying to compile drivers/bios_emulator for RISC-V, I get a
bunch of the following warnings:

Hi all,
To all owners & active users of the SiFive Unmatched board: do you have success
running any recent upstream U-Boot on your system?
I use the default U-Boot from Ubuntu 24.04, and it boots GRUB and Linux
kernel just fine. Today I flashed the unmodified U-Boot 2024.07 (compiled with

Hi all,
I enabled CONFIG_DM_DEBUG on my SiFive Unmatched, and U-Boot boot results in
failed assertion ("ofnode_valid(node)"). I'm attaching the full log below.
The same behavior is also for the 2024.10 stable version.

Hi Heinrich; hi all owners of SiFive Unmatched + PCIe video card,
Default U-Boot configuration for Unmatched always fails to initialize
BAR0 of my video card (NVidia GT710), because the PCI driver selects the MEMORY
region at 0x7000 for bus_start/phys_start ("region 2", according to
decode_reg
uot;region 1" instead (the one which starts at 0x6009),
because
it has much bigger size (0xFF7), and easily accomodates BAR0 of the video
card.
Linux kernel also uses 0x6009 as bus_start/phys_start.

This patch adds missing DECODE_PRINTF("\n") calls to print newlines.

When DEBUG_DECODE_F is enabled in bios_emulator, the printing of BSF
instructions is garbled because the '\n' symbol is used instead of
the correct '\t'. Fix that.
