Subject: [PATCHv2] powerpc: Add support for POWER10
Date: Thu, 25 Jun 2020 20:01:16 -0300 [thread overview]
Message-ID: <20200625230116.301613-1-tuliom@linux.ibm.com> (raw)
In-Reply-To: <87ftaikc1i.fsf@linux.ibm.com>
Changes since v1:
- Remove 2 directories from Implies. Added another directory that was
missing.
- Listed power10 in preconfigure.ac
---8<---
1. Add the directories to hold POWER10 files.
2. Print the correct values for AT_PLATFORM and AT_BASE_PLATFORM.
3. Let submachine=power10 be set automatically.
