From 7065b7d466dfc4fbfa8a608cf21206efe59c01d9 Mon Sep 17 00:00:00 2001 From: Ruchika Gupta Date: Wed, 15 Dec 2010 17:02:08 +0000 Subject: powerpc/p4080: Add support for secure boot flow Pre u-boot Flow: 1. User loads the u-boot image in flash 2. PBL/Configuration word is used to create LAW for Flash at 0xc0000000 (Please note that ISBC expects all these addresses, images to be validated, entry point etc within 0 - 3.5G range) 3. ISBC validates the u-boot image, and passes control to u-boot at 0xcffffffc. Changes in u-boot: 1. Temporarily map CONFIG_SYS_MONITOR_BASE to the 1M CONFIG_SYS_PBI_FLASH_WINDOW in AS=1. (The CONFIG_SYS_PBI_FLASH_WINDOW is the address map for the flash created by PBL/configuration word within 0 - 3.5G memory range. The u-boot image at this address has been validated by ISBC code) 2. Remove TLB entries for 0 - 3.5G created by ISBC code 3. Remove the LAW entry for the CONFIG_SYS_PBI_FLASH_WINDOW created by PBL/configuration word after switch to AS = 1 Signed-off-by: Ruchika Gupta Signed-off-by: Kuldip Giroh Acked-by: Wood Scott-B07421 Signed-off-by: Kumar Gala --- include/configs/corenet_ds.h | 4 ++++ 1 file changed, 4 insertions(+) (limited to 'include') diff --git a/include/configs/corenet_ds.h b/include/configs/corenet_ds.h index ca3229bc65..d5fc19b531 100644 --- a/include/configs/corenet_ds.h +++ b/include/configs/corenet_ds.h @@ -698,4 +698,8 @@ #define CONFIG_BOOTCOMMAND CONFIG_HDBOOT +#ifdef CONFIG_SECURE_BOOT +#include +#endif + #endif /* __CONFIG_H */ -- cgit
