Ard Biesheuvel 17054f492d efi/x86: Implement mixed mode boot without the handover protocol ... Add support for booting 64-bit x86 kernels from 32-bit firmware running on 64-bit capable CPUs without requiring the bootloader to implement the EFI handover protocol or allocate the setup block, etc etc, all of which can be done by the stub itself, using code that already exists. Instead, create an ordinary EFI application entrypoint but implemented in 32-bit code [so that it can be invoked by 32-bit firmware], and stash the address of this 32-bit entrypoint in the .compat section where the bootloader can find it. Note that we use the setup block embedded in the binary to go through startup_32(), but it gets reallocated and copied in efi_pe_entry(), using the same code that runs when the x86 kernel is booted in EFI mode from native firmware. This requires the loaded image protocol to be installed on the kernel image's EFI handle, and point to the kernel image itself and not to its loader. This, in turn, requires the bootloader to use the LoadImage() boot service to load the 64-bit image from 32-bit firmware, which is in fact supported by firmware based on EDK2. (Only StartImage() will fail, and instead, the newly added entrypoint needs to be invoked) Signed-off-by: Ard Biesheuvel <ardb@kernel.org>		2020-02-23 21:59:42 +01:00
