I am porting uClinux 2.6.x to a Micro/sys SBC1625 board.
The processor of this board is a IXP420BB.
My need is to use of "File-backed Storage Gadget".
I have find some problems in the
..../linux-2.6.x/drivers/usb/gadget/pxa2xx_udc.c.
For compile and execute this file I have :
- include <asm/arch/ixp4xx-regs.h> rather than <asm/arch/pxa-regs.h>
- add "#define IXP420_BB 0x000001F1" for the IXP420BB processor
- add the case below :
#elif defined(CONFIG_ARCH_IXP4XX)
case IXP425_A0:
case IXP420_BB: <-----------------------
out_dma = 0;
break;
#endif
- comments the lines :
static int __exit pxa2xx_udc_remove(struct platform_device *pdev)
{
struct pxa2xx_udc *dev = platform_get_drvdata(pdev);
udc_disable(dev);
remove_proc_files();
usb_gadget_unregister_driver(dev->driver);
if (dev->got_irq) {
free_irq(IRQ_USB, dev);
dev->got_irq = 0;
}
/* if (machine_is_lubbock()) { <----------
free_irq(LUBBOCK_USB_DISC_IRQ, dev); <----------
free_irq(LUBBOCK_USB_IRQ, dev); <----------
} */ <----------
platform_set_drvdata(pdev, NULL);
the_controller = NULL;
return 0;
}
because LUBBOCK_USB_DISC_IRQ and LUBBOCK_USB_IRQ are defined for the
ixp4xx.
Is it necessary to make something for the ixp4xx ?
For me it is OK, my kernel is compiled.
Some of these modifications are perhaps good the future kernel.
Who collect informations for kernel modifications ?
Best regards.
