Subject: riscv/virt: Increase flash size
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6911fde41006b2afe3510755c4cff259ca56c1d9;p=qemu.git

riscv/virt: Increase flash size

Coreboot developers have requested that they have at least 32MB of flash
to load binaries. We currently have 32MB of flash, but it is split in
two to allow loading two flash binaries. Let's increase the flash size
from 32MB to 64MB to ensure we have a single region that is 32MB.

No QEMU release has include flash in the RISC-V virt machine, so this
isn't a breaking change.
