In separating the configuration of littlefs from the physical geometry of the underlying device, we can no longer rely solely on lfs_config to contain all of the information necessary for the simulated block devices we use for testing. This adds a new lfs_*bd_config struct for each of the block devices, and new erase_size/erase_count fields. The erase_* name was chosen since these reflect the (simulated) physical erase size and count of erase-sized blocks, unlike the block_* variants which represent logical block sizes used for littlefs's bookkeeping. It may be worth adopting erase_size/erase_count in littlefs's config at some point in the future, but at the moment doesn't seem necessary. Changing the lfs_bd_config structs to be required is probably a good idea anyways, as it moves us more towards separating the bds from littlefs. Though we can't quite get rid of the lfs_config parameter because of the block-device API in lfs_config. Eventually it would be nice to get rid of it, but that would require API breakage.
