[U-Boot-Users] Support for ALTERA FPGAs
Hi there,
the patch attached adds support for ALTERA FPGAs. For now only the ACEX1K using the so called "passive serial" Interface.
The code and idea is heavily stolen from the xilinx stuff. And just like there the board specific code has to provide some functions for handling the FPGA signals CONF_DONE, DATA, DCLK, nCONFIG, nSTATUS.
I thought I release it quite early to avoid redundant work done by others and hope this could be a usefull starting point for people using Altera FPGAs.

Mostly added. There is a small bug in the patch, which I tried to fix:

You add "altera.o" which is already present in the list of objects ? [Also you ignore ordering :-( ]
Added, thanks. Will show up on CVS soon.

Oops.
I've overseen the altera.o. And I did not know that order here is important! Why is it? Why was altera at.o the beginning of the list? Is it in alphabetical order?

For esthetical reasons, and and easo of work, and reliability. Searching an item or verifying if it already exists is much easier if such lists are kept sorted.

Indeed.

how long does it usually take for your changes to appear on sourceforge?
Because there still not there? :-(

I'm sorry, ther eis little I can do but hope the situation will improve soon as SF has been promising for some time. Please feel free to check the CVS status page at SF at http://sourceforge.net/docman/display_doc.php?docid=2352&group_id=1#cvs
