Glasgow Embedded / Glasgow - History

access: add name hints to generated TSTriples.

This makes PNR reports more useful, e.g.:

Info: Max frequency for clock 'lpcapplet_lclk_i_$glb_clk': 54.32 MHz (PASS at 30.00 MHz)

instead of:

Info: Max frequency for clock 'lpcapplet_tstriple2_i_$glb_clk': 46.29 MHz (PASS at 30.00 MHz)

applet.jtag_xc9500: add missing JTAG state machine fixes.

Forgot to update FVFY and FPGMI.

applet.jtag_xc9500: running commands requires going via Update-IR/DR.

The JTAG applet has been fixed to take a minimal path through
the JTAG state machine, which unfortunately broke a few downstream
applets.

firmware: fix illegal IOx manipulation.

Something like:

IOx |= 0x02;
IOx &= 0x01;

doesn't guaranteed to work unless both of those are already outputs,
since writing an 1 (or 0) to an input doesn't change the value read
back.

In practice this results in weird inconsistent bugs due to board-to-
board variability.

Fixes #77.
