[U-Boot-Users] Support for ALTERA FPGAs

[U-Boot-Users] Support for ALTERA FPGAs

[Steven Scholz]

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.

* Patch by Steven Scholz, 10 Oct 2003
   - Add support for Altera FPGA ACEX1K

Cheers,

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
