[PATCH 08/27] arc: Add BCR and AUX registers implementation
cupertinomiranda at gmail.com
cupertinomiranda at gmail.com
Mon Apr 5 15:31:19 BST 2021
From: Cupertino Miranda <cmiranda at synopsys.com>
Add the infrastructure to define build configuration (BCR) and auxiliary
registers allowing independent modules (MMU, MPU, etc.) to use and extend
them.
