If HV relocation is enabled, either ACRN efi-stub or GRUB relocates hypervisor image above HPA 256MB, thus we put hvlog and ramoops buffer under 256MB to avoid conflict with hypervisor owned address. This patch hardcodes these addresses: 0xa00000 - 0xdfffff: 4MiB for ramoops buffer 0xe00000 - 0xffffff: 2MiB for hvlog buffer However, user can customize them to other addresses as long as it's under 256MB, available in host e820, and SOS bootarg "nokaslr" is not specified. If HV relocation is disabled, need to make sure that these buffer addresses are not between HV_RAM_START and HV_RAM_START + HV_RAM_SIZE.
