commented Jan 15, 2019

Hi Paolo,
Liam posted a new version of "[PATCH v3 0/4] QEMU changes to do PVH boot" that includes a patch that I wrote in order to support initrd.
This PR contains a patch for qboot to support this feature.


If we found initrd through fw_cfg, we can load it and use the
first module of hvm_start_info to pass initrd address and size
to the kernel.
