To: u-boot
I've tried to search the mailing list but was unable to do so. I am assuming
that this board has no support at the momemt.
What is Avila ?
===============
This is an affordable Xscale development platform as well as a usable,
off-the-shelf Wireless AP/Router platform.
This platform is based on the IXDP425 but has some minor differences most of
which are contained in the config file. This board has its own mach-type
defined by Linux so I've added that to board/ixdp425/ixdp425.c and also put
in the board information string.
More information on these boards can be found here:
http://www.gateworks.com/avila_processors.htm
Which tree does this apply to ?
===============================
IXP custodian tree: u-boot-ixp.git
What is supported/tested with this patch ?
==========================================
* Boot from flash (JFFS2 or raw image)
* NPE Ethernet (you will need NPE microcode from Intel).
I am working on a patch for supporting the CF IDE interface on this board
which I will submit separately.

I don't think it is a good idea to add lots of #ifdefs for another
board in some board specific file.
There are different boards, so they should have separate board
specific files. If you find larger parts of common code, please feel
free to factor this out.
As is, I don't want to accept this patch for the publich U-Boot tree.
Best regards,
Wolfgang Denk

What is wanted is not the will to believe, but the will to find out,
which is the exact opposite.
