From 544293f87850b415721690533dae2d27f77f44f3 Mon Sep 17 00:00:00 2001 From: "Park, Aiden" Date: Sat, 3 Aug 2019 08:30:12 +0000 Subject: x86: Add new slimbootloader CPU type This slimbootloader CPU type is to enable U-Boot as a payload which runs on top of Slim Bootloader (https://github.com/slimbootloader). The Slim Bootloader is designed with multi-stage architecture for the execution from reset vector to OS booting, and supports QEMU, Apollolake, Whiskeylake and Coffeelake platforms consuming Intel FSP (https://github.com/IntelFsp) for silicon initialization including CAR and memory initialization. The Slim Bootloader generates new HOB (Hand Off Block) which are serial port info, memory map info, performance data info and so on, and passes it to a Payload. U-Boot as a payload will use these HOB information for basic initialization such as serial console. As an initial commit, - Add CONFIG_SYS_SLIMBOOTLOADER to enable slimbootloader CPU type - Add new arch/x86/cpu/slimbootloader directory with minimum codes - Get hob_list pointer from Slim Bootloader Signed-off-by: Aiden Park Reviewed-by: Bin Meng Reviewed-by: Andy Shevchenko Tested-by: Bin Meng --- arch/x86/include/asm/global_data.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/x86/include') diff --git a/arch/x86/include/asm/global_data.h b/arch/x86/include/asm/global_data.h index 9398ec33b2..797397e697 100644 --- a/arch/x86/include/asm/global_data.h +++ b/arch/x86/include/asm/global_data.h @@ -83,7 +83,7 @@ struct arch_global_data { const struct pch_gpio_map *gpio_map; /* board GPIO map */ struct memory_info meminfo; /* Memory information */ struct pei_memory_info pei_meminfo; /* PEI memory information */ -#ifdef CONFIG_HAVE_FSP +#ifdef CONFIG_USE_HOB void *hob_list; /* FSP HOB list */ #endif struct mtrr_request mtrr_req[MAX_MTRR_REQUESTS]; -- cgit
