2021-11-04commonlib/mem_pool: Allow configuring the alignmentRaul E Rangel
AMD platforms require the destination to be 64 byte aligned in order to use the SPI DMA controller. This is enforced by the destination address register because the first 6 bits are marked as reserved. This change adds an option to the mem_pool so the alignment can be configured.

2021-04-06mem_pool: Track the last two allocations (not just one)Julius Werner
This patch changes the mem_pool implementation to track the last two allocations (instead of just the last) and allow them both to be freed if the mem_pool_free() calls come in in reverse order. This is intended as a specific optimization for the CBFS cache case when a compressed file is mapped on a platform that doesn't natively support memory-mapping flash. In this case, cbfs_map() (chaining through to _cbfs_alloc() with allocator == NULL) will call mem_pool_alloc(&cbfs_cache) to allocate space for the uncompressed file data. It will then call cbfs_load_and_decompress() to fill that allocation, which will notice the compression and in turn call rdev_mmap_full() to map the compressed data (which on platforms without memory-mapped flash usually results in a second call to mem_pool_alloc(&cbfs_cache)). It then runs the decompression algorithm and calls rdev_munmap() on the compressed data buffer (the latter one in the allocation sequence), leading to a mem_pool_free(). The remaining buffer with the uncompressed data is returned out of cbfs_map() to the caller, which should eventually call cbfs_unmap() to mem_pool_free() that as well. This patch allows this simple case to succeed without leaking any permanent allocations on the cache. (More complicated cases where the caller maps other files before cbfs_unmap()ing the first one may still lead to leaks, but those are very rare in practice.)

As discussed on the mailing list and voted upon, the coreboot project is going to move the majority of copyrights out of the headers and into an AUTHORS file. This will happen a bit at a time, as we'll be unifying license headers at the same time.

Some of the files need to be adjusted so that they can be used both in cbfstool as well as coreboot proper. For coreboot, add a <sys/types.h> file such that proper types can be included from both the tools and coreboot. The other chanes are to accomodate stricter checking in cbfstool.

It encourages users from writing to the FSF without giving an address. Linux also prefers to drop that and their checkpatch.pl (that we imported) looks out for that. This is the result of util/scripts/no-fsf-addresses.sh with no further editing.

2015-09-22coreboot: introduce commonlibAaron Durbin
Instead of reaching into src/include and re-writing code allow for cleaner code sharing within coreboot and its utilities. The additional thing needed at this point is for the utilities to provide a printk() declaration within a <console/console.h> file. That way code which uses printk() can than be mapped properly to verbosity of utility parameters.
