mtd: Correct dependency of BLK

2025-01-21T01:26:54Z

In the case of MTD_BLOCK and UBI_BLOCK they should be select'ing BLK as they provide block device functionality and not depending on some other block device already being enabled too (as is the typical case). Reviewed-by: Quentin Schulz Reviewed-by: Peter Robinson Signed-off-by: Tom Rini

mtd: ubi: Do not zero out EC and VID on ECC-ed NOR flashes

2024-10-15T14:57:49Z

For NOR flashes EC and VID are zeroed out before an erase is issued to make sure UBI does not mistakenly treat the PEB as used and associate it with an LEB. But on some flashes, like the Infineon Semper NOR flash family, multi-pass page programming is not allowed on the default ECC scheme. This means zeroing out these magic numbers will result in the flash throwing a page programming error. Do not zero out EC and VID for such flashes. A writesize > 1 is an indication of an ECC-ed flash.

drivers: introduce UBI block abstraction

2024-08-08T07:28:00Z

UBI block is an virtual device, that runs on top of the MTD layer. The blocks are UBI volumes. Intended to be used in combination with other MTD drivers. Despite the fact that it, like mtdblock abstraction, it used with UCLASS_MTD, they can be used together on the system without conflicting. For example, using bcb command: # Trying to load bcb via mtdblock: $ bcb load mtd 0 mtd_partition_name # Trying to load bcb via UBI block: $ bcb load ubi 1 ubi_volume_name User always must attach UBI layer (for example, using ubi_part()) before using UBI block device.
