Patches fix timer interrupt and debug UART support for dLAN USB Extender. Kernel boots now and you can connect to the UART for early console output. Kernel is too big to fit in 1MB so I changed MTD to automatic partition splitting.
Platform device support is broken since kernel 3.14 and needs to be fixed. I don't know yet how to fix this stuff. As you can see in the boot log from 3.14.35 there's something wrong with interrupt resources for USB and ethernet... (was working with kernel 3.3.8) @Florian Fainelli: do you have any clue what's been broken from 3.3.8 to 3.14? boot log (3.14.35): [ 5.170000] ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver [ 5.180000] mcs814x-ehci 400fc000.ehci: Found HC with no IRQ.
