Merge branch 'board-specific' of git://github.com/hzhuang1/linux into late/boardboards2
From Haojian Zhuang <haojian.zhuang@gmail.com>:
* 'board-specific' of git://github.com/hzhuang1/linux:
ARM: pxa: hx4700: Use DEFINE_RES_* macros consistently
ARM: pxa: remove eseries.h
It seems I missed this in the original pull requests for v3.6, adding
it now.
