[PATCH v2 12/13] ARM: lpc32xx: clean up header files

From: Arnd Bergmann
Date: Fri Aug 09 2019 - 10:46:15 EST


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.
