From 671c08ec007b2f859d9075fc9bc0c06320c90cd4 Mon Sep 17 00:00:00 2001 From: Andrew Davis Date: Mon, 13 Nov 2023 08:43:59 -0600 Subject: [PATCH] ARM: mach-nspire: Rework support and directory structure Having a platform need a mach-* directory should be seen as a negative, it means the platform needs special non-standard handling. ARM64 support does not allow mach-* directories at all. While we may not get to that given all the non-standard architectures we support, we should still try to get as close as we can and reduce the number of mach directories. The mach-nspire/ directory and files, provides just one "feature": having the kernel print the machine name if the DTB does not also contain a "model" string (which they always do). To reduce the number of mach-* directories let's do without that feature and remove this directory. NOTE: The default l2c_aux_mask is now ~0 but these devices never have this type of cache controller so this is safe.
