From 51c14cd128f4355514397dc3c8647fb14f7d8ff4 Mon Sep 17 00:00:00 2001 From: Teddy Reed Date: Thu, 9 Jun 2016 19:18:44 -0700 Subject: verified-boot: Minimal support for booting U-Boot proper from SPL This allows a board to configure verified boot within the SPL using a FIT or FIT with external data. It also allows the SPL to perform signature verification without needing relocation. The board configuration will need to add the following feature defines: CONFIG_SPL_CRYPTO_SUPPORT CONFIG_SPL_HASH_SUPPORT CONFIG_SPL_SHA256 In this example, SHA256 is the only selected hashing algorithm. And the following booleans: CONFIG_SPL=y CONFIG_SPL_DM=y CONFIG_SPL_LOAD_FIT=y CONFIG_SPL_FIT=y CONFIG_SPL_OF_CONTROL=y CONFIG_SPL_OF_LIBFDT=y CONFIG_SPL_FIT_SIGNATURE=y Signed-off-by: Teddy Reed Acked-by: Simon Glass Acked-by: Andreas Dannenberg Acked-by: Sumit Garg --- drivers/Makefile | 1 + drivers/crypto/rsa_mod_exp/mod_exp_sw.c | 1 + 2 files changed, 2 insertions(+) (limited to 'drivers') diff --git a/drivers/Makefile b/drivers/Makefile index f6295d285e..db5317c9c7 100644 --- a/drivers/Makefile +++ b/drivers/Makefile @@ -10,6 +10,7 @@ obj-$(CONFIG_$(SPL_)RAM) += ram/ ifdef CONFIG_SPL_BUILD +obj-$(CONFIG_SPL_CRYPTO_SUPPORT) += crypto/ obj-$(CONFIG_SPL_I2C_SUPPORT) += i2c/ obj-$(CONFIG_SPL_GPIO_SUPPORT) += gpio/ obj-$(CONFIG_SPL_MMC_SUPPORT) += mmc/ diff --git a/drivers/crypto/rsa_mod_exp/mod_exp_sw.c b/drivers/crypto/rsa_mod_exp/mod_exp_sw.c index dc6c064b4e..3817fb3e47 100644 --- a/drivers/crypto/rsa_mod_exp/mod_exp_sw.c +++ b/drivers/crypto/rsa_mod_exp/mod_exp_sw.c @@ -32,6 +32,7 @@ U_BOOT_DRIVER(mod_exp_sw) = { .name = "mod_exp_sw", .id = UCLASS_MOD_EXP, .ops = &mod_exp_ops_sw, + .flags = DM_FLAG_PRE_RELOC, }; U_BOOT_DEVICE(mod_exp_sw) = { -- cgit v1.2.1
