From e69cc6bc42c37598e2fdda421360be6cbc0470fd Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Thu, 23 Aug 2018 21:28:58 -0700 Subject: x86: zimage: Remove acpi_rsdp_addr propagation to kernel boot parameters As of today, the proposal of adding "acpi_rsdp_addr" to the kernel boot protocol does not make its way to the kernel mainline. This creates some confusion if we leave it in the U-Boot code base. Remove it for now until we have a clear picture with kernel upstream. Note this eventually does a partial revert to commit 3469bf427454 ("x86: zImage: Propagate acpi_rsdp_addr to kernel via boot parameters") Signed-off-by: Bin Meng Acked-by: Andy Shevchenko Reviewed-by: Simon Glass --- arch/x86/include/asm/bootparam.h | 1 - arch/x86/lib/zimage.c | 5 ----- 2 files changed, 6 deletions(-) (limited to 'arch/x86') diff --git a/arch/x86/include/asm/bootparam.h b/arch/x86/include/asm/bootparam.h index 0386cbe..dfbd4b4 100644 --- a/arch/x86/include/asm/bootparam.h +++ b/arch/x86/include/asm/bootparam.h @@ -69,7 +69,6 @@ struct setup_header { __u64 pref_address; __u32 init_size; __u32 handover_offset; - __u64 acpi_rsdp_addr; } __attribute__((packed)); struct sys_desc_table { diff --git a/arch/x86/lib/zimage.c b/arch/x86/lib/zimage.c index 0442fda..230b38e 100644 --- a/arch/x86/lib/zimage.c +++ b/arch/x86/lib/zimage.c @@ -287,11 +287,6 @@ int setup_zimage(struct boot_params *setup_base, char *cmd_line, int auto_boot, hdr->hardware_subarch = X86_SUBARCH_INTEL_MID; #endif -#ifdef CONFIG_GENERATE_ACPI_TABLE - if (bootproto >= 0x020e) - hdr->acpi_rsdp_addr = acpi_get_rsdp_addr(); -#endif - setup_device_tree(hdr, (const void *)env_get_hex("fdtaddr", 0)); setup_video(&setup_base->screen_info); -- cgit v1.1
