Raw Nand devices are best handled in a eraseblock oriented way. Also these devices need a proper bad block handling. The regular mtd API is stream oriented (at least for read/write). Using these functions includes unhandy use of 64bit arithmetics and handling erasing blocks and bad blocks requires us to align the offset back to block boundaries. The UBI IO layer already has a nice API to handle Nand blockwise. This series strips the API out of the UBI code and makes it available for other users. It's names the mtd-peb API (peb for Physical Erase Block). UBI and ubiformat are converted to this API in this series. Another user will be the i.MX internal nand update code which is converted in another series. Since UBI and ubiformat now share more code this series makes the image a little smaller. Hurray, it's been some time since this last happened.
