47 "erase_size" is the minimum size, in bytes, of an erase
48 operation. For MMC, "erase_size" is the erase group size
50 to trim or secure trim operations where the minimum size is

23 Erase `size' bytes starting at offset `off'. Alternatively partition
24 name can be specified, in this case size will be eventually limited
25 to not exceed partition size (this behaviour applies also to read
26 and write commands). Only complete erase blocks can be erased.
28 If `erase' is specified without an offset or size, the entire flash
29 is erased. If `erase' is specified with partition but without an
30 size, the entire partition is erased.

22 Example of using u-boot command
25 SF: Detected S25FL256S_64K with page size 256 Bytes, erase size 64 KiB, total 32 MiB
26 => sf erase 0 +<size of rcw image>
28 => sf write <rcw image in memory> 0 <size of rcw image>
31 To get the QSPI image, build u-boot with QSPI config, for example,
