49 Moved the location of the ZIPSYSTEM in memory, made the artyboard.h constants
more friendly and more complete, fixed two bugs in the CPU (jumps to breaks,
and s/w clearing of icache), added a NO_USERMODE option to the CPU, and more.
Rebuild any user programs before using this build.		 dgisselq 2752d 14h /openarty/trunk/rtl/fastio.v
36 Lots of changes, see the git changelog for details. dgisselq 2779d 03h /openarty/trunk/rtl/fastio.v
34 These updates bring the distribution along to the point where both the GPS
clock subsecond tracking, as well as the OLEDrgb controller now work.		 dgisselq 2782d 17h /openarty/trunk/rtl/fastio.v
25 The memory now works. However, the core speed has been lowered to 81.25MHz
to do this. The top level file is no longer fasttop.v, but toplevel.v.		 dgisselq 2825d 23h /openarty/trunk/rtl/fastio.v
19 Creates an LED mask portion of writing to the LED's register. Only those
bits specified in the mask (bits [7:4]) will be adjusted in the LED
register on a write. Hence to set all on, set the LED register to 0x0ff,
all off, 0x0f0, or to set LED 0 to on while leaving the others unchanged,
set it to 0x011.		 dgisselq 2854d 19h /openarty/trunk/rtl/fastio.v
17 Fixed the misaddressed I/O peripherals in the fastio peripheral group. In
particular, UART and GPS were misaddressed. This has now been fixed, so these
peripherals (should) match the spec. Further, the default speed of the two
UARTs has been adjusted to 115200/8N1 for the aux UART, and 9600/8N1 for the
GPS UART. The Aux UART transmitter also passes testing, so at least that one
works.		 dgisselq 2856d 18h /openarty/trunk/rtl/fastio.v
3 Initial set of files. The flash appears to work, memory hasn't been started,
the MDIO controller works in simulation, etc. Everything below fasttop.v works
at 200MHz (not the CPU---yet).		 dgisselq 2873d 02h /openarty/trunk/rtl/fastio.v
