NetBSD 7.99.71 (GUMSTIX) #68: Tue May 2 19:47:52 CEST 2017

>Description:
Gumstix Connex/Verdex is started
If no boot parameter `busheader` for a GPIO extension board is given but a extenstion board with a PCMCIA adapter is connected a kernel debugging assertion is triggered for the default GUMSTIX kernel.
pxapcic0 at pxaip0 addr 0x20000000: 1 slot
[...]
panic: kernel debugging assertion "gpio < GPIO_NPINS" failed: file "/usr/src/sys/arch/arm/xscale/pxa2x0_gpio.c", line 446
The kernel probes a pcmcia slot but doesn't setup the IRQ-pins. Later card s in the slot are read by using invalid PIN "-1" aka 0xFFFFFFF.
>How-To-Repeat:
boot a GUMSTIX Connex/Verdex board with PCMCIA extension board present but without busheader parameter.
Assertion occure. Expected no assertion occure and no pcmcia slot is available.
pxapcic0 at pxaip0 addr 0x20000000: 0 slot
[...]
boot device: <unknown>
root device:
See below for suggested patch. The gxpcic now configures only valid slots and always uses the sc_irqcfpin & sc_irqpin array instead of its own copy.
Tested with an NetCF (@connex) and NetCF-Pro (@verdex) with and without the correct busheader parameter.
