Message-Id: <20190809144043.476786-13-arnd@arndb.de>

Subject: [PATCH v2 12/13] ARM: lpc32xx: clean up header files
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@...il.com>
