      [ARM] pxa: add support for additional GPIOs on PXA26x · 067455aa
      Eric Miao 提交于
      Original patch from Marek Vasut, the problems with PXA26x are:
      
      1. there are additional 4 GPIOs 86,87,88,89 have their direction bits
         inverted in GPDR2, as well as their alternate function bits being
         '1' for their GPIO functionality in GAFRx
      
      2. there is no easy way to decide if the processor is a pxa26x or a
         pxa250/pxa255 at run-time, so the assumption here is the pxa26x
         will be treated as one of the pxa25x variants, and board code
         should have a better knowledge of the processor it is featured
      
      Introduce pxa26x_init_irq() for the second purpose, and treat the
      additional GPIOs > 85 on PXA25x specially.
      
      Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code
      a bit when PXA26x support isn't needed. Board config options have
      to select this to enable the support for PXA26x.
      
      __gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x
      isn't selected.

      [ARM] 5295/1: make ZONE_DMA optional · 3bca103a
      Nicolas Pitre 提交于
      Most ARM machines don't need a special "DMA" memory zone, and
      when configured out, the kernel becomes a bit smaller:
      
      |   text    data     bss     dec     hex filename
      |3826182  102384  111700 4040266  3da64a vmlinux
      |3823593  101616  111700 4036909  3d992d vmlinux.nodmazone
      
      This is because the system now has only one zone total which effect is
      to optimize away many conditionals in page allocation paths.
      
      So let's configure this zone only on machines that need split zones.
