I could imaging a function orion_ge00_irq_init(struct mv643xx_eth_platform_data *eth_data, unsigned long mapbase, unsigned int tx_csum_limit) which does the irq lookup and then calls orion_ge00_init().
Andrew, sure. Feel free to move legacy code to where all SoCs can use it.
Jason: what is the status of the ethernet driver conversion to DT? Will it get merged this week, or is it material for the next merge window?
What I remember from Florian's work it was close to be released. I never saw Florian sending an update to his patches, maybe he ran out of time? I guess DT timer will be a quick patch when we have all SoCs running on DT irqchip and maybe Florian can update his patches even before we sort out Thomas request. Then we could also merge DT timer within this patch set and get rid of legacy helpers before we even introduce them.
