memory: remove MODULE_LICENSE in non-modules 2023-03-09T14:20:50+00:00 Nick Alcock nick.alcock@oracle.com 2023-03-08T20:21:17+00:00 d2456ddb2e7e1b89ed637e8190fcbbeadc7ea8a7 Since commit 8b41fc4454e3 ("kbuild: create modules.builtin without Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations are used to identify modules. As a consequence, uses of the macro in non-modules will cause modprobe to misidentify their containing object file as a module when it is not (false positives), and modprobe might succeed rather than failing with a suitable error message. So remove it in the files in this commit, none of which can be built as modules.

Since commit 8b41fc4454e3 ("kbuild: create modules.builtin without
Makefile.modbuiltin or tristate.conf"), MODULE_LICENSE declarations
are used to identify modules. As a consequence, uses of the macro
in non-modules will cause modprobe to misidentify their containing
object file as a module when it is not (false positives), and modprobe
might succeed rather than failing with a suitable error message.

So remove it in the files in this commit, none of which can be built as
modules.

memory: Add Baikal-T1 L2-cache Control Block driver 2020-05-28T12:17:41+00:00 Serge Semin Sergey.Semin@baikalelectronics.ru 2020-05-26T12:59:28+00:00 83ca8b3e8f213f49cc68b5c1fbcf88ebb24671eb Baikal-T1 SoC provides a way to tune the MIPS P5600 CM2 L2-cache performance up. It can be done by changing the L2-RAM Data/Tag/WS latencies in a dedicated register exposed by the system controller. The driver added by this commit provides a dts properties-based and sysfs-based interface for it. The device DT node is supposed to be a child of Baikal-T1 System Controller node.
