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 Cypress Semper S28 SPI 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.
