The Microchip PolarFire SoC support is implemented as a riscv BSP variant to boot with any individual hart(cpu core) or SMP based on the boot HARTID configurable and support components are 4 CPU Cores (U54), Interrupt controller (PLIC), Timer (CLINT), UART.
2022-09-19Do not use RTEMS_INLINE_ROUTINESebastian Huber137-982/+982
Directly use "static inline" which is available in C99 and later. This brings the RTEMS implementation closer to standard C. Close #3935.

All CPU ports used the same _CPU_Counter_difference() implementation. Remove this CPU port interface and mandate a monotonically increasing CPU counter. Close #3456.

2022-09-08lib: further adoption of SPDX licensing ID tags.Pedro F. Giffuni3-2/+8
Mainly focus on files that use BSD 2-Clause license, however the tool I was using mis-identified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts.

We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Special thanks to Wind River for providing access to "The Duke of Highlander" tool: an older (2014) run over FreeBSD tree was useful as a starting point.

2022-09-08Implement SHA2-224 submode of SHA2-256Conrad Meyer2-0/+113
Like SHA2-384:SHA2-512, SHA2-224 is simply a truncated SHA2-256 with a different initial vector. Add to round out the complete basic SHA2 family.
2022-09-08Fix C++ includability of crypto headers with static array sizesAlan Somers4-5/+10
C99 allows array function parameters to use the static keyword for their sizes. This tells the compiler that the parameter will have at least the specified size, and calling code will fail to compile if that guarantee is not met. However, this syntax is not legal in C++. This commit reverts r300824, which worked around the problem for sys/sys/md5.h only, and introduces a new macro: min_size(). min_size(x) can be used in headers as a static array size, but will still compile in C++ mode.

2022-09-08Retune SHA2 code for improved performance on CPUsColin Percival2-190/+198
with more ILP and a preference for memory load instructions over large code footprints with embedded immediate variables. On amd64 CPUs from 2007-2008 there is not a significant change, but amd64 CPUs from 2009-2010 get roughly 10% more throughput with this code; amd64 CPUs from 2011-2012 get roughly 15% more throughput; and AMD64 CPUs from 2013-2015 get 20-25% more throughput. The Raspberry Pi 2 increases its throughput by 6-8%. Sponsored by: Tarsnap Backup Inc. Performance tested by: allanjude MFC after: 3 weeks
2022-09-08Implement SHA-512 truncated (224 and 256 bits)Allan Jude2-0/+150
This implements SHA-512/256, which generates a 256 bit hash by calculating the SHA-512 then truncating the result. A different initial value is used, making the result different from the first 256 bits of the SHA-512 of the same input. SHA-512 is ~50% faster than SHA-256 on 64bit platforms, so the result is a faster 256 bit hash. The main goal of this implementation is to enable support for this faster hashing algorithm in ZFS. The feature was introduced into ZFS in r289422, but is disconnected because SHA-512/256 support was missing. A further commit will enable it in ZFS.

2022-09-08crypto routines: Hint minimum buffer sizes to the compilerConrad Meyer5-9/+10
Use the C99 'static' keyword to hint to the compiler IVs and output digest sizes. The keyword informs the compiler of the minimum valid size for a given array. Obviously not every pointer can be validated (i.e., the compiler can produce false negative but not false positive reports). No functional change. No ABI change.

2022-09-08powerpc: Add support for VRSAVESebastian Huber3-15/+92
The VRSAVE feature of the Altivec unit can be used to reduce the amount of Altivec registers which need to be saved/restored during interrupt processing and context switches. In order to use the VRSAVE optimization a corresponding multilib (-mvrsave) is required, see GCC configuration. The -mvrsave option must be added to the ABI_FLAGS of the BSP. Currently only the -mcpu=e6500 based QorIQ BSP support this optimization. Update #4712.
