Subject: [PATCH 09/10] ARM: mach-lpc18xx: Rework support and directory structure
Date: Mon, 15 May 2023 11:02:33 -0500	[thread overview]
Message-ID: <20230515160234.289631-9-afd@ti.com> (raw)
In-Reply-To: <20230515160234.289631-1-afd@ti.com>

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-lpc18xx/ 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.
