Subject: riscv: qemu: Remove fdt_high default
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=62f1afbe7a8ae8f8b9e85c5ea4eb446b97892a7c;p=thirdparty%2Fu-boot.git

riscv: qemu: Remove fdt_high default

Setting fdt_high to all ones is discouraged and does not appear to be
useful for RISC-V QEMU. Moreover, it causes a boot failure when the FDT
generated internally by QEMU is used while booting. Remove it to allow
U-Boot to pick a suitable address and relocate the FDT.
