[Xenomai-core] iMX25 problem with gpio and xenomai

[Roberto Bielli]

Hi,

i'm doing the porting of xenomai version 2.5.6 on imx25 board and i'm 
looking to start from imx27.
I have some problem with gpio. It seems there are spurious interrupts.
I would know what xenomai want to know about interrupts (i see 
ipipe_handle_irq_cond in gpio handler, is it needed ?) and registry save 
(spin_lock_irqsave .... in mxc_gpio_set etc...)

Thanks a lot
