This patch series includes two changes to the SBI heap implementation, primarily
to enable future work on the SMMTT implementation. First, it enables allocations
from multiple independent heaps on separate memory regions. Then, it adds a simple
implementation for sbi_memalign for use in allocating aligned memory.

See the individual commit messages in this series for more technical details.

v4:
- Rename sbi_memalign{_from} -> sbi_aligned_alloc{_from}
- Miscellaneous code format changes

v3:
- Add missing Signed-off-by lines
- Rename struct heap_control -> struct sbi_heap_control
- Make various functions static inline in sbi_heap.h
- Fix previously incorrect sbi_memalign() implementation

Gregor Haas (3):
  lib: sbi: Support multiple heaps
  lib: sbi: Allocate from beginning of heap blocks
  lib: sbi: Implement aligned memory allocators
