* Only attempts if FPU actually implemented in design
* Also initializes rounding modes, which are undefined at reset
|
|
This way, chips with FPU can run FPU instructions without taking
exceptions.
I've confirmed that dhrystone still runs successfully even on chips
with no FPU.

* Bump tool versions
* Use version of OpenOCD which can load programs into flash
* Bump OpenOCD to Handle ISSI Flash Programming
* Update Header files
* add initial support for hifive1
* add dhrystone
* add clock helper functions
* add openocd cfg file
* Demo_GPIO checkpoint -- compiles and runs but no blinky LEDs
* Remove riscv-tests submodule
* Remove FPGA files, as they are no longer relevant to this Repository
* Add openocd_upload script
* Add Pinmux Mappings
Adding the pinmux mappings to the Platform Header
* Add IOF Mappings to platform header
* Re-order the IOF Mapping declarations
* Add more useful things to platform headers
* Get GPIO Demo working again (except interrupts aren't working)
* Update README with more OS packages needed
A bare ubuntu-16.04.1-server installation could not run `make tools`
without these packages.
* bump openocd to get SCKDIV fix
* Remove duplicated help text for run_debug target
* Add package to README that is needed for openocd build
Without this package I was seeing two different failures like below
when running `make tools`.

* Roll back CoreMark
