2018-08-18Added easier to read chip_select/reset functions.Piotr Esden-Tempski
Just calling a gpio function with two numbers was not very self explanatory. The functions now refer to the actual indended action, chip (de)select for flash, reset and chip (de)select for sram. Reading the code and understanding what steps are taken should be easier now.
2018-08-16Added more code comments.Piotr Esden-Tempski
Main point was to group the code into three logical segments: * MPSSE/FTDI defines and functions * FLASH defines and functions * iceprog implementation core While I was at it I also added a few comments for stuff that was not immediately obvious what it does.

2018-07-19icebox_hlc2asc: fix _lut_ keyword parsingElms
'self.lut_bits is None' was always false. The _lut_ keyword is used by asc2hlc, so when converting asc->hlc->asc the lut_bits were always all zeros.

Previously if you were doing; `icebox_vlog example.asc > example_bit.v` you would just get; ``` Traceback (most recent call last): File "icebox_vlog.py", line 947, in <module> assert False AssertionError ``` Now you get; ``` Traceback (most recent call last): File "icebox_vlog.py", line 948, in <module> assert False, "\n ".join(emsg) AssertionError: Single-driver-check failed for 2 nets: n10 has 0 drivers: [] n15 has 2 drivers: ['clk', 'clk2'] ```

This is done by sorting all the commands inside a block. Doing so makes it much easier to diff two files.

2018-06-12HLC: Use '~>' instead of '<->' for routing switches.Tim 'mithro' Ansell
As mentioned in ca6b2d9ebd521ecec58b9b5627c9380355adeab1, the 'routing' switches are not actually bidirectional. This makes the '<->' specifier very misleading. Instead use '~>' to differentiate it from the 'buffer' switches.
2018-06-12icebox_hlc2asc: Remove the bidirectional support.Tim 'mithro' Ansell
See ca6b2d9ebd521ecec58b9b5627c9380355adeab1.
