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 --- Kconfig | 11 +++++++++++ 1 file changed, 11 insertions(+) (limited to 'Kconfig') diff --git a/Kconfig b/Kconfig index 4b46216665..817f4f08a0 100644 --- a/Kconfig +++ b/Kconfig @@ -183,6 +183,11 @@ config FIT verified boot (secure boot using RSA).
