[PATCH 01/22] ARM: clps711x: Reduce static map size

From: Alexander Shiyan <hidden>
Date: 2016-06-04 07:09:53
Subsystem: arm port, the rest · Maintainers: Russell King, Linus Torvalds

Last CLPS711X CPU register is PLLR has 0xa5a8 address, so we can reduce
the map to 48k and align the end of the static at VMALLOC_START.
