From afa39105d8e09e5bc9ce2053b10a40839ab9fddd Mon Sep 17 00:00:00 2001 From: Subrata Banik Date: Sat, 18 May 2024 12:26:40 +0000 Subject: libpayload: Add x86_64 (64-bit) support 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 Reviewed-on: https://review.coreboot.org/c/coreboot/+/81968 Reviewed-by: Julius Werner Tested-by: build bot (Jenkins) --- payloads/libpayload/libc/exec.c | 52 ----------------------------------------- 1 file changed, 52 deletions(-) delete mode 100644 payloads/libpayload/libc/exec.c (limited to 'payloads/libpayload/libc/exec.c') diff --git a/payloads/libpayload/libc/exec.c b/payloads/libpayload/libc/exec.c deleted file mode 100644 index ae75a3e510..0000000000 --- a/payloads/libpayload/libc/exec.c +++ /dev/null @@ -1,52 +0,0 @@ -/* - * - * Copyright (C) 2008 Advanced Micro Devices, Inc. - * - * Redistribution and use in source and binary forms, with or without - * modification, are permitted provided that the following conditions - * are met: - * 1.
