Note this driver assumes some control bits are accessed via a single r/w register, not by GPIO or something (this sux, my board uses GPIO). See drivers/mtd/spia.c for an example. You will also need a ROM (OTPROM, EPROM, EEPROM, NOR Flash) based bootloader since SA1110 has no NAND access feature. Don't forget to link NAND support and JFFS2 in kernel or use an initial ramdisk with them as modules. -- Paul Chitescu [EMAIL PROTECTED] http://pchitescu.myip.org/ ICQ:22641673 Any spammers will be painfully squeezed into /dev/null _______________________________________________ http://lists.arm.linux.org.uk/mailman/listinfo/linux-arm http://www.arm.linux.org.uk/armlinux/mailinglists.php Please visit the above addresses for information on this list.
