Hey Alex, There's a tutorial on making such a block on the wiki (including the files you need to add it to the toolflow). I wrote it whilst at the workshop last year, so its only tested to the extent that I could communicate from one gpio to another and then back again. Note that the roach gpios are buffered, and the block doesn't control this, you have to explicitly use the gpio_oe_n blocks in addition to the bidirectional gpio block. Feel free to give me a shout if it causes you bother.
