2021-09-09Kconfig: Drop duplicate 'select SHA512' instancesTom Rini
When dropping SHA512_ALGO in general, we didn't catch some cases where an option was selecting both SHA512 and SHA512_ALGO and caused them to select SHA512 twice. Kconfig doesn't complain, but this is still wrong and should be corrected.

2021-09-08common: Move MD5 hash to hash_algo[] array.Alexandru Gagniuc
MD5 is being called directly in some places, but it is not available via hash_lookup_algo("md5"). This is inconsistent with other hasing routines. To resolve this, add an "md5" entry to hash_algos[]. The #ifdef clause looks funnier than those for other entries. This is because both MD5 and SPL_MD5 configs exist, whereas the other hashes do not have "SPL_" entries. The long term plan is to get rid of the ifdefs, so those should not be expected to survive much longer. The md5 entry does not have .hash_init/update/finish members. That's okay because hash_progressive_lookup_algo() will catch that, and return -EPROTONOSUPPORT, while hash_lookup_algo() will return the correct pointer.

2021-09-08lib: Drop SHA512_ALGO in lieu of SHA512Alexandru Gagniuc
SHA512_ALGO was used as a "either SHA512 or SHA384", although the implementations of these two algorithms share a majority of code. From a Kconfig interface perspective, it makes sense to present two distinct options. This requires #ifdefing out the SHA512 implementation from sha512.c. The latter doesn't make any sense. It's reasonable to say in Kconfig that SHA384 depends on SHA512, and seems to be the more polite way to handle the selection. Thus, automatically select SHA512 when SHA384 is enabled.

2021-08-21display_options: Do not use %llu in print_sizeMatwey V. Kornilov
tiny-printf variant doesn't know how to handle %llu format string, but both tiny-printf and print_size can meet in SPL when TFTP is used to obtain main u-boot image. This is known to lead to critical boot issue at AM335x platform when printf is catched in infinite loop. To avoid such issues and make print_size function tiny-printf friendly, use %u instead of %luu. Note, that the size value is guaranteed to be less than 1024 in this conditional branch, so the cast to unsigned int is safe. Signed-off-by: Matwey V.

2021-08-02lib: Allow using 0x when a decimal value is requestedSimon Glass
U-Boot mostly uses hex for value input, largely because addresses are much easier to understand in hex. But in some cases a decimal value is requested, such as where the value is small or hex does not make sense in the context. In these cases it is sometimes useful to be able to provide a hex value in any case, if only to resolve any ambiguity. Add this functionality, for increased flexibility.

2021-07-24smbios: Fix calculating BIOS Release DatePali Rohár
BIOS Release Date must be in format mm/dd/yyyy and must be release date. U-Boot currently sets BIOS Release Date from U_BOOT_DMI_DATE macro which is generated from current build timestamp. Fix this issue by setting U_BOOT_DMI_DATE macro to U-Boot version which is better approximation of U-Boot release date than current build timestamp. Current U-Boot versioning is in format yyyy.mm so as a day choose 01. Some operating systems are using BIOS Release Date for detecting when was SMBIOS table filled or if it could support some feature (e.g. BIOS from 1990 cannot support features invented in 2000). So this change also ensures that recompiling U-Boot from same sources but in different year does not change behavior of some operating systems. Macro U_BOOT_DMI_DATE is not used in other file than lib/smbios.c so remove it from global autogenerated files and also from Makefile.
