Well, right now I have a slightly different view, because of the work on the FIQ stuff. We currently have the situation where the GIC on CT9x4 appears to be different from other GICs, in that group 1 interrupts are never delivered. As the GIC is indistinguishable from working parts, this currently squarely puts the Daniel's KGDB FIQ work, and work to use FIQ for dumping backtraces in the case of a spinlock lockup beyond the reach of the kernel right now, and nothing more than a local hack. So, until we get to the bottom of this, I need Versatile Express support to stay as-is, so there's no extraneous variables in the platform. That means right now I need the legacy stuff to stay as switching to DT will add a huge variable into what's going on. -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net.
