[PATCHv7 0/4] omap: iovmm - fixes for iovmm module

[Fernando Guzman Lugo]

Misc fixes found while working with iovmm module. They are
needed in order to tidspbridge can work properly along with
iovmm module.

Version 7:
* Change 4/4 patch base on Felipe Contreras comments about
  having start/end in platform data and struct iommu.

Version 6:
* Rebase on Russell King branch.
 - for details see:
 http://marc.info/?l=linux-omap&m=129228495723001&w=2

Version 5:
* Changes in "iommu: create new api to set valid da range"
 - Change range variables to platform data structure.

Version 4:
* Changes in "iommu: create new api to set valid da range"
 - Validate range for fixed address.
 - Change way of change boundaries to avoid possible overflow
  instead of style :
     start + bytes >= end     which start + end can overflow
  use style:
     end - start < bytes

Version 3:
* change patch 2 base on Felipe Contreras' comments,
 now it uses min_t and I deleted some blank lines.
* patch "create new api to set valid da range" is base on
 "iovmm: IVA2 MMU range is from 0x11000000 to 0xFFFFFFFF"
 patch and on Hiroshi's comments and now it is added to
 this set.

Version 2:
* Removed "iovmm: fixes for iovmm module" that patch was already
 sent.
* Modified "iovmm: fix roundup for next area and end check for the
 last area" patch, base on Davin Cohen's comments and rename it
 to a proper name that describes what it is doing now.
