Hello everyone, while working on NAND flash support for a custom board based on the at91 SAM9X60 SoC I stumbled over some issues in the raw nand subsystem.
Four of six patches are minor fixes. Patch 4 introduces a new subcommand for the new atmel nand controller driver. Patch 6 introduces a new subcommand for the nand command to override ONFI timing mode. Both are are for debugging purposes only and thus optional, and need to be enabled through menu. Both helped me a lot when investigating issues. Series is based on upstream next branch, but should also apply to master cleanly.
