ArmVirtualizationPkg: add a relocatable version of PrePi This patch introduces a relocatable PrePi, which can execute from arbitrary offsets in RAM. This is intendend to be run from a boot loader which passes a description of the actual platform in a device tree, for instance. This module is based on the PrePi implementations residing under ArmPlatformPkg.

ArmVirtualizationPkg: Xen: shuffle init order to deal with incoherency In order to prevent memory corruption issues caused by the fact that, under virtualization, the guest is incoherent with the hypervisor's view of memory until it enables its caches and MMU, this patch reshuffles the init sequence so that the Xen shared memory regions are not touched before the caches and MMU are enabled. In addition, the loaded image itself is invalidated by virtual address, to ensure that any runtime changes (such as the applied relocations) will not suddenly become invisible once we turn the caches on.

ArmVirtPkg/ArmVirtPrePiUniCoreRelocatable: revert to PIE linking In some cases, the CLANG38 toolchain profile in LTO mode emits GOT based relocations in spite of our attempts to avoid this, by using hidden visibility, -Bsymbolic etc. On AARCH64, we managed to work around this by processing the GOT based relocations in GenFw. As it turns out, the same issue exists on 32-bit ARM, but unfortunately, we cannot use a similar trick to get rid of the GOT entry, and the relocation metadata is insufficient to locate the GOT entry in the binary. Note that in this particular case, we are interested in PIE linking only (i.e., producing a .rela section containing dynamic relocations that the startup code can process directly), and not in position independent code generation, and by passing the -pie option to the linker directly using -Wl,-pie (and dropping -shared), we can coerce the GOLD linker into doing only the former rather than both when it performs its LTO code generation.
