hi Haavard,

There is an issue with the current at91_nand driver here.
The driver currently ioremap()'s the ECC controller's registers, but on the AT91 the ECC controller is part of the System Peripherals and so it is already mapped at startup. I don't think it can/should be remapped twice.
The AT91 patch (on maxim.org.za) current does: regs = platform_get_resource(pdev, IORESOURCE_MEM, 1); .... host->ecc = (void __force __iomem *) (AT91_VA_BASE_SYS - AT91_BASE_SYS); host->ecc += regs->start; instead of the ioremap(). But this is not portable to the AVR32.
