2021-06-21MIPS: OCTEON: octeon-usb: Use devm_platform_get_and_ioremap_resource()Yang Yingliang1-8/+1
Remove unneeded error handling on the result of a call to platform_get_resource() when the value is passed to devm_ioremap_resource(). And use devm_platform_get_and_ioremap_resource() to simplify code. Signed-off-by: Yang Yingliang <yangyingliang@huawei.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>

2021-01-19Revert "MIPS: Octeon: Remove special handling of CONFIG_MIPS_ELF_APPENDED_DTB=y"Kevin Hao1-3/+6
This reverts commit d9df9fb901d25b941ab2cfb5b570d91fb2abf7a3. For the OCTEON boards, it need to patch the built-in DTB before using it. Previously it judges if it is a built-in DTB by checking fw_passed_dtb. But after commit 37e5c69ffd41 ("MIPS: head.S: Init fw_passed_dtb to builtin DTB", the fw_passed_dtb is initialized even when using built-in DTB. This causes the OCTEON boards boot broken due to an unpatched built-in DTB is used. Revert the commit d9df9fb901d2 to restore the codes before the fw_passed_dtb is used and then fix this issue.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers3-3/+3
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

2020-05-08crypto: lib/sha1 - remove unnecessary includes of linux/cryptohash.hEric Biggers1-1/+0
<linux/cryptohash.h> sounds very generic and important, like it's the header to include if you're doing cryptographic hashing in the kernel. But actually it only includes the library implementation of the SHA-1 compression function (not even the full SHA-1). This should basically never be used anymore; SHA-1 is no longer considered secure, and there are much better ways to do cryptographic hashing in the kernel. Most files that include this header don't actually need it. So in preparation for removing it, remove all these unneeded includes of it.
