TECHNICAL NOTE

Summary of 2021 patchworks
Background
As a world-wide leader in non-volatile memory, Macronix is committed to provide best quality products and
constantly devotes to offer advanced features that benefit customers' system performance, low power, and
versatile. Macronix has worked closely with most popular communities like Linux or mbed OS to enable new
features readyto-use through driver patching and comprehensive verification.
It is delightful to summarize our progress for your reference on the note. In 2021, we have developed 15
patchworks on either Linux or u-boot, 9 of them have been accepted and merged into the mainlines. Even the other
6 are under review, users can still visit our website for early adoption. Our patchworks span four categories: new
devices, new features, optimization, and interface controllers. Users can figure out more information in this note
and go visit repos on the github and patchworks on Macronix website.
