ARM hardfp port related documentation.
There are notes on rpm bootstrapping and OBS importing.
armv7hl = -mfloat-abi=hard -mfpu=vfpv3-d16 -march=armv7-a -mno-thumb
armv7nhl = -mfloat-abi=hard -mfpu=neon -march=armv7-a -mno-thumb
MeeGo.com baseline would be armv7hl, vendors can recompile for armv7hln if they so wanted
Currently, there're also plans to use thumb2:
armv7thl = -mfloat-abi=hard -mfpu=vfpv3-d16 -march=armv7-a -mthumb
armv7tnhl = -mfloat-abi=hard -mfpu=neon -march=armv7-a -mthumb
