2017-05-04	Update SDK For E31/E51 Coreplex IP Evaluation	Megan Wachs

2017-01-11	reduce code duplication and apply the same flags to Arty board	mwachs5

2017-01-11	Add the 'bootloader' which ships on HiFive1 Boards.	mwachs5

2017-01-03	Regularize timing code	Andrew Waterman
	Provide get_timer_value() and get_timer_freq() and use them. On Arty, they use mcycle and the known-fixed core frequency, whereas on HiFive1 they use mtime and the known-fixed mtime frequency.
2017-01-03	Improve HiFive1 CPU frequency measurement routine	Andrew Waterman
	- Warm up I$ first. - Correct for integer division truncation error. - Wait for an RTC clock edge before starting the timing loop, which removes an error proportional to the number of loop iterations, allowing us to run for far less time.
2016-12-20	Pass argc and argv to main()	Andrew Waterman

2016-12-14	Refactor libc stubs into libwrap	Albert Ou
	The --wrap feature of GNU ld supports a cleaner framework for linking in alternative implementations of libc functions without cpp hacks. Place wrappers in separate object files to reduce static code size.
2016-12-13	Use more standard form of _init()	Megan Wachs

2016-12-09	demo_gpio: Correct trap_entry handling to enable timer/ext interrupts	Megan Wachs

2016-12-07	Initialize FPU properly	Scott Johnson
	* Only attempts if FPU actually implemented in design * Also initializes rounding modes, which are undefined at reset
2016-12-06	Enable FPU in MSTATUS CSR during init	Scott Johnson
	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.
2016-11-30	Bump Everything to Match new Freedom Repo (#8)	Megan Wachs
	* 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`. /home/scottj/freedom-e-sdk/openocd/configure: line 4533: syntax error near unexpected token `0.23' /home/scottj/freedom-e-sdk/openocd/configure: line 4533: `PKG_PROG_PKG_CONFIG(0.23)' Makefile:70: recipe for target '/home/scottj/freedom-e-sdk/toolchain/bin/openocd' failed make: * [/home/scottj/freedom-e-sdk/toolchain/bin/openocd] Error 2 ... or ... + autoconf configure.ac:12: error: possibly undefined macro: AC_MSG_WARN If this token and others are legitimate, please use m4_pattern_allow.
