When build option ABOVE_4G_MEMORY is set to true, nothing will change
and EDKII will use all available memory.

Setting it to false will create memory type information HOB in
payload entry, so that EDKII will reserve enough memory below 4G
for EDKII modules. This option is useful for bootloaders that are not
fully 64-bit aware such as Qubes R4.0.4 bootloader, Zorin and Proxmox.

Subject: [PATCH] UefiPayloadPkg: Add build option for Above 4G Memory

When build option ABOVE_4G_MEMORY is set to true, nothing will change
and EDKII will use all available memory.

Setting it to false will create memory type information HOB in
payload entry, so that EDKII will reserve enough memory below 4G
for EDKII modules. This option is useful for bootloaders that are not
fully 64-bit aware such as Qubes R4.0.4 bootloader, Zorin and Proxmox.
