econet: switch to new spi/spi-nand drivers
This change produces incompatibility with old flash structure, thus it's not possible to upgrade old devices (special installation procedure is required). There benefits as well: * opensource driver * more flashes supported * better support of spare area * more space on the flash is available * no special UBI related hack is required * no double bad block management Upgrade procedure: 0) get new 'u-boot-nand.bin' and 'squashfs.itb' images 1) backup 'art' partition 2) rename u-boot-nand.bin image to tcboot.bin and flash it: * reboot board and keep it in the bootloader * put tcboot.bin to the board using binary tftp node * wait for flashing complete and reboot board * new bootloader will start * execute "run format_ubi" from u-boot command line * rename "squashfs.itb" file to "image.itb" and put it to TFTP server on your PC * execute "run update_itb" twice from u-boot command line * execute "setenv board_id rodimus && saveenv" from u-boot command line * reboot board, new image will be booted. 3) restore 'art' partition Downgrade procedure: 0) get old bootloader and 'squashfs.itb' images 1) rename old bootloader to "uboot-nand.bin" and put it to TFTP server on your PC 2) reboot board and keep it in the bootloader 3) execute "run update_uboot" from u-boot command line 4) wait for flashing complete and reboot board to start old bootloader 5) flash old images and recover art partition
