Subject: [PATCH 2/3] ARM: add LS1021A to Layerscape machine support
Renaud Barbier
Renaud.Barbier at ametek.com
Wed Mar 1 08:59:54 PST 2023
This updates the Layerscape support in preparation for the
introduction of the LS1021A-IOT:
- Makefile/Kconfig
- LS1021A specific register maps and configurations
- errata workarounds update
