Subject: [PATCH V1] powerpc: Placeholder and infrastructure/build support to add Power11 related changes.
Date: Wed, 6 Mar 2024 08:57:04 -0500 [thread overview]
Message-ID: <20240306135705.1417833-1-amritahs@linux.vnet.ibm.com> (raw)
The following three changes have been added to provide
initial Power11 support.
1. Add the directories to hold Power11 files.
2. Add support to select Power11 libraries based on AT_PLATFORM.
3. Let submachine=power11 be set automatically.
