Simon Schubert be0bca0230 u4k: add SMCCLK cell location 
icecube uses SMCCLK.CLK to "legalize" output cells.  Unclear what this
is for, but it appears in almost all outputs.

Nathan Rossi c1c13f3b3e icetime: Add support for searching for chipdb relative to binary 
Like yosys and arachne-pnr, allow for searching for the desired chipdb
file relative to the executing binaries directory. This allows for
portable builds of icetime without needing to specify the exact path to
the needed chipdb file with the -C arg.

In order to support this icetime must be able to get the
"proc_self_dirname" path just like yosys and arachne-pnr. As such copy
the equivalent code to get this path information. To avoid cluttering
the icetime.cc file with this code, place it in a separate iceutil.cc
file.

Piotr Esden-Tempski 9a58588772 Slightly more robust flash wait function. 
In cases when the FLASH chip is bit flaky and the status register
"bounces" this flash_wait should be able to perform a bit better.

Also added more verbose output around block erase.
 2018-08-18 16:13:27 -07:00
Piotr Esden-Tempski 868ac2d93f Add a function to read and decode the status register. 
Very useful for debugging purposes. ;)

Piotr Esden-Tempski 20ef4efd8b Added the FTDI cable pinout for reference. 2018-08-18 15:29:11 -07:00
Piotr Esden-Tempski f4ff8f7630 Improved JEDEC ID read function. 
The function now checks how long the extended JEDEC ID field is for the
particular FLASH chip and only reads the amount provided by the chip.
 2018-08-18 15:26:37 -07:00
Piotr Esden-Tempski 3ba1acf31b Replaced some more magic numbers with FLASH command IDs. 
I missed those the first time around.
 2018-08-18 14:46:12 -07:00
Piotr Esden-Tempski ee7eae0be8 Added easier to read chip_select/reset functions. 
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.
 2018-08-18 14:41:42 -07:00
Piotr Esden-Tempski 96b1a90f28 Added more code comments. 
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.
