Building and running Linux on Cyclone-II

When you build u-boot, you specify a specific board. The board(s) in question were

not supported by u-boot. So someone (the 'You') needs to add the support in the

source tree before u-boot will work on those board(s).

Virtually all GNU projects (and most open-source projects) contain a file named

README. It's actually part of the GNU coding standards:

gnu coding standards:<div class='quotetop'>QUOTE </div>

--- Quote Start ---

The distribution should contain a file named ‘README’ which gives the name of the

package, and a general description of what it does.[/b]

--- Quote End ---

You should read the README file. In this case, it contains a section relevant to the discussion (how to

add support for a board).

In many cases, boards based on the same CPU architecture (e.g. Nios-II) can use

the same or similar code. The common way to add support for a board is to just

copy the code for an existing board and then make the necessary changes.

In this particular case, the code in the board/altera/ep1c20 tree (or "directory

hierarchy") is a good choice as the source of the copy.

Hope this helps.
