50a64e5b | 2 | Provides services to allocate and free memory buffers of various memory types and alignments.\r |
8789c5e0 | 3 | \r |
4 | The Memory Allocation Library abstracts various common memory allocation operations. This library \r | |
5 | allows code to be written in a phase-independent manner because the allocation of memory in PEI, DXE, \r | |
6 | and SMM (for example) is done via a different mechanism. Using a common library interface makes it \r | |
7 | much easier to port algorithms from phase to phase. \r | |
