drivers: crypto: mod_exp_sw: Re-add DM_FLAG_PRE_RELOC

2020-05-19T18:01:47Z

This driver is safe to use in SPL without relocation. Denying DM_FLAG_PRE_RELOC prevents its usability for verifying the main U-Boot or other artifacts from the SPL unless needless enabling the full driver set (SPL_OF_PLATDATA).

drivers: crypto: rsa_mod_exp: avoid DM_FLAG_PRE_RELOC

2020-04-16T06:12:32Z

Function rsa_verify_key() is not called before relocation. So there is no need to load the UCLASS_MOD_EXP drivers before relocation. This avoid a failure to boot for pine64-lts_defconfig with CONFIG_RSA=y. Signed-off-by: Heinrich Schuchardt

crypto: make mod_exp_sw() static

2020-01-25T17:04:36Z

Function mod_exp_sw() is only used via the operators of the uclass. It is not defined in any include. Make mod_exp_sw() static. Signed-off-by: Heinrich Schuchardt

drivers: crypto: rsa_mod_exp: Add manual relocation for ops->mod_exp()

This patch adds manual relocation for Modular Exponentiation if CONFIG_NEEDS_MANUAL_RELOC is enabled. Signed-off-by: T Karthik Reddy Signed-off-by: Siva Durga Prasad Paladugu Signed-off-by: Michal Simek

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

verified-boot: Minimal support for booting U-Boot proper from SPL

2016-06-12T17:14:58Z

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

rsa : Compile Modular Exponentiation files based on CONFIG_RSA_SOFTWARE_EXP

2015-03-05T20:04:59Z

Remove dependency of rsa_mod_exp from CONFIG_FIT_SIGNATURE. As rsa modular exponentiation is an independent module and can be invoked independently. Signed-off-by: Gaurav Rana Acked-by: Simon Glass Reviewed-by: York Sun
