2024-05-26libpayload: Add x86_64 (64-bit) supportSubrata Banik
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>
2023-12-01libpayload: Fix the stack and data labelsYi Chou
We should make sure _stack/_estack and the other labels are consistent. And _data & _edata is also useful to clean up the sensitive data on the data section.

This will allow more payloads to use the standard linker script instead of implementing their own.

2013-02-14libpayload; put the ldscript into an arch-dependent directory pathRonald G. Minnich
Since it's utterly architecture-dependent, put it in arch/x86. Avoid the temptation to make yet another directory with just one file in it. Fix the makefile to pick up the proper arch-dependent script. Change-Id: I21ea02551a97bdcbc38419714f3b38cf8335c178 Signed-off-by: Ronald G.
