Proposal[edit]

Add mcespi driver to openwrt once tested.

mcespi is a module wrote in assembler and targeted for big endian cpus newer than MIPS32r1 that accelerates MD5, SHA1 and AES in software.

Considerations[edit]

As issues with the proposal come to mind or are raised by reviewers, capture them in the considerations section of the PRIP. As appropriate, explain the trade offs of the proposed design and why a particular decision was made. This section may provide the most value for developers and users that follow later so do not be afraid to list everything that comes to mind. Rare is it that a proposal doesn't have some negatives to consider.
