-Subject: [PATCH] axs103: Support slave core kick-start on axs103 v1.1
- firmware
-
-In axs103 v1.1 procedure to kick-start slave cores has changed quite a bit
-compared to previous implementation.
-
-In particular:
- * We used to have a generic START bit for all cores selected by CORE_SEL
- mask. But now we don't touch CORE_SEL at all because we have a dedicated
- START bit for each core:
- bit 0: Core 0 (master)
- bit 1: Core 1 (slave)
- * Now there's no need to select "manual" mode of core start
-
-Additional challenge for us is how to tell which axs103 firmware we're
-dealing with. For now we'll rely on ARC core version which was bumped
-from 2.1c to 3.0.
