Some nand flashes (like spi-nand one) are registered with mtd subsystem only, thus nand command can't be used to work with such flashes. As result some functionality is missing.
This patch series introduce following features: * 'mtd markbad' command (clone of 'nand markbad') * 'mtd nand_write_test' command (clone of 'nand torture') Also a new command 'mtd nand_read_test' introduced. It produce readonly test of flash. It's mostly usefull to: * check general flash state, * check the correctness of returned number of corrected bits. The were no any activities around a patch series for almost 2 weeks. Seems the patches were lost, so resend them one more time. Miquel Raynal, could you confirm message receiving? I am afraid that these messages could go to your spam folder as my other mails.
