Subject: [PATCH v2 12/13] ARM: lpc32xx: clean up header files
Date: Fri,  9 Aug 2019 16:40:38 +0200
Message-ID: <20190809144043.476786-13-arnd@arndb.de> (raw)
In-Reply-To: <20190809144043.476786-1-arnd@arndb.de>

All device drivers have stopped relying on mach/*.h headers,
so move the remaining headers into arch/arm/mach-lpc32xx/lpc32xx.h
to prepare for multiplatform builds.

The mach/entry-macro.S file has been unused for a long time now
and can simply get removed.

Acked-by: Sylvain Lemieux <slemieux.tyco@gmail.com>
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
