2021-04-14doc: signature.txt: Document the keydir and keyfile argumentsAlexandru Gagniuc
After lots of debating, this documents how we'd like mkimage to treat 'keydir' and 'keyfile' arguments. The rest is in the docs. Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2021-04-14test/py: ecdsa: Add test for mkimage ECDSA signingAlexandru Gagniuc
Add a test to make sure that the ECDSA signatures generated by mkimage can be verified successfully. pyCryptodomex was chosen as the crypto library because it integrates much better with python code. Using openssl would have been unnecessarily painful. Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2021-04-14lib: Add support for ECDSA image signingAlexandru Gagniuc
mkimage supports rsa2048, and rsa4096 signatures. With newer silicon now supporting hardware-accelerated ECDSA, it makes sense to expand signing support to elliptic curves. Implement host-side ECDSA signing and verification with libcrypto. Device-side implementation of signature verification is beyond the scope of this patch.

2021-04-14lib/rsa: Make fdt_add_bignum() available outside of RSA codeAlexandru Gagniuc
fdt_add_bignum() is useful for algorithms other than just RSA. To allow its use for ECDSA, move it to a common file under lib/. The new file is suffixed with '-libcrypto' because it has a direct dependency on openssl. This is due to the use of the "BIGNUM *" type.

To prevent confusion, move this file to lib/, and rename it to hash-checksum.c, to give it a more "generic" feel.

2021-04-12cmd: exit: Fix return valueMarek Vasut
In case exit is called in a script without parameter, the command returns -2 ; in case exit is called with a numerical parameter, the command returns -2 and lower. This leads to the following problem: => setenv foo 'echo bar ; exit 1' ; run foo ; echo $? bar 0 => setenv foo 'echo bar ; exit 0' ; run foo ; echo $? bar 0 => setenv foo 'echo bar ; exit -2' ; run foo ; echo $? bar 0 That is, no matter what the 'exit' command argument is, the return value is always 0 and so it is not possible to use script return value in subsequent tests. Fix this and simplify the exit command such that if exit is called with no argument, the command returns 0, just like 'true' in cmd/test.c. In case the command is called with any argument that is positive integer, the argument is set as return value. => setenv foo 'echo bar ; exit 1' ; run foo ; echo $? bar 1 => setenv foo 'echo bar ; exit 0' ; run foo ; echo $? bar 0 => setenv foo 'echo bar ; exit -2' ; run foo ; echo $? bar 0 Note that this does change ABI established in 2004 , although it is unclear whether that ABI was originally OK or not.

2021-04-12scmi: translate the resource only when livetree is not activatedPatrick Delaunay
Call the translation function on the ofnode_read_resource result only when the livetree is not activated. Today of_address_to_resource() calls ofnode_read_resource() for livetree support and fdt_get_resource() when livetree is not supported. The fdt_get_resource() doesn't do the address translation so when it is required when livetree is activated but this address translation is already done by ofnode_read_resource().

2021-04-12checkpatch: Add warnings for using strn(cat|cpy)Sean Anderson
strn(cat|cpy) has a bad habit of not nul-terminating the destination, resulting in constructions like strncpy(foo, bar, sizeof(foo) - 1); foo[sizeof(foo) - 1] = '\0'; However, it is very easy to forget about this behavior and accidentally leave a string unterminated. This has shown up in some recent coverity scans [1, 2] (including code recently touched by yours truly). Fortunately, the guys at OpenBSD came up with strl(cat|cpy), which always nul-terminate strings. These functions are already in U-Boot, so we should encourage new code to use them instead of strn(cat|cpy).

Each row in the pixel array in the bitmap file is padded if necessary so the row size is always a multiple of 4 bytes. In current code the complement of row size to a multiple of 4 bytes is further unnecessarily multiplied by the pixel size. This results in incorrect displaying of bitmaps having row size that is not a multiple of 4 bytes. Fix this by removing the unnecessary multiplication. Tested with 24BPP bitmap and XRGB32 display.
