Re: value of XIP? and whether it works with 2.6 kernel?

In message [ref] you wrote:

   as i read it from david w's post on the MTD list, XIP has limited
value since flash is noticeably more expensive than RAM anyway.

The fact that flash is more expensive does NOT mean that XIP  has  no
use.  Actually  this  is nonsense. There are several good reasons why
using XIP may be a good idea. For example, in some security  critical
environments users are much more happy to execute code from read-only
storage. Also boot time may be an issue.

   so, thoughts?  who's actually using this?  and it's not clear from
the DENX page that there's a patch for the 2.6 kernel -- that page
refers specifically to 2.4.

We use it on 2.4 with 8xx only (so far).

   anyway, i'm just curious, wondering whether it would be worth giving
it a try, just for the entertainment value.

Go on...

Best regards,
