 - new tool 'dtx_diff' to diff DT files

 - sync kernel's dtc/libfdt to current dtc repo master

 - fix for reserved memory regions located in highmem

 - document standard unit suffixes for DT properties

 - various DT binding doc updates

Standard Unit Suffixes for Property names



Properties which have a unit of measure are recommended to have a unit

suffix appended to the property name. The list below contains the

recommended suffixes. Other variations exist in bindings, but should not

be used in new bindings or added here. The inconsistency in the unit

prefixes is due to selecting the most commonly used variants.



It is also recommended to use the units listed here and not add additional

unit prefixes.
