This patch introduces x86_64 (64-bit) support to the payload, building upon the existing x86 (32-bit) architecture. Files necessary for 64-bit compilation are now guarded by the `CONFIG_LP_ARCH_X86_64` Kconfig option. BUG=b:242829490 TEST=Able to verify all valid combinations between coreboot and payload with this patch. Payload Entry Point Behavior with below code. +----------------+--------------------+----------------------------+ | LP_ARCH_X86_64 | Payload Entry Mode | Description | +----------------+--------------------+----------------------------+ | No | 32-bit | Direct protected mode init | +----------------+--------------------+----------------------------+ | Yes | 32-bit | Protected to long mode | +----------------+--------------------+----------------------------+ | Yes | 64-bit | Long mode initialization | +----------------+--------------------+----------------------------+ Change-Id: I69fda47bedf1a14807b1515c4aed6e3a1d5b8585 Signed-off-by: Subrata Banik <subratabanik@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/81968 Reviewed-by: Julius Werner <jwerner@chromium.org> Tested-by: build bot (Jenkins) <no-reply@coreboot.org> |
