Subject: qfw/acpi: do not zero out XSDT address
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=33355013ffce4fe58d552db3dd546ecf197a7a9b;p=thirdparty%2Fu-boot.git

qfw/acpi: do not zero out XSDT address

On RISC-V QEMU provides an XSDT table. The RSDP table points to it.
We must not zero out this pointer because otherwise no ACPI table can be
found.
