Reorganization and updated README file
Updated recommended ISE version
Renamed the flash binary file for clarity
Fixed unintentional ignore of edk/*/data/*.xml.  Would be a problem for 7010 projects.
Merge branch 'master' of https://github.com/parallella/parallella-hw
Brought in changes from Andreas.
Added I2C interface to all projects, will always work for u-boot but will not be available to users unless added to device tree.
Changed version register format.
Removed 'k' from named defines.
Added getbits scripts to move & rename bitstreams to a top-level 'bitstreams' directory.
Added bitstreams & 'getbits' scripts.
Added ability to change elink and gpio iostandards.
Fixed TXI/TXO & RXI/RXO on wait (pushback) signals.
Mods for E64, changed version register.
Forgot IO standards for the GPIOs on E16 projects.
Bitstreams w/ new version register structure.
E64 uses LVDS for eLink.
No GPIOs imlemented, but there are still LVDS Rcvrs/Xmtrs on the GPIO pins (12 and 12).
Fixed all the GPIO##_P / RXI_DATA#_P / HDMI_D## madness.
Created gpio module for diff/se for either 7010 or 7020.
GPIOs are now connected to PS/EMIO GPIOs in all targets,
  should be accessible by arms.
Minor update to readme.
Minor update to readme.
Merge https://github.com/parallella/parallella-hw
(Should not be necessary, I managed to confuse my local repo)
Minor update to readme.
Updated edk projects to correct SDRAM info.
Changed the 'fpga/bitstreams' directory to contain board-ready binary files instead of the raw bitfile output of ISE.
This is supported by new versions of 'getbits' in each project folder.
Note that bootgen (which creates the binaries) does not do the right thing if the only file in the .bif is the bitfile,
to work around this I added dummy.elf files which are converted and then deleted.
Pull getbits / bitstreams changes into local repo.
