Author: ian Date: Mon Feb 25 16:40:10 2019 New Revision: 344525 URL: https://svnweb.freebsd.org/changeset/base/344525 Log: Add a metadata entry for the AT45DB641E chip. This chip has the same 3-byte jedec ID as its older cousin the AT45DB642D, but uses a different page size. The only way to distinguish between the two chips is that the 2D chip has 0 bytes of extended ID info and the new 1E has 1 byte of extended ID. The actual value of the extended ID byte is all zeroes. In other words, it's the presence of the extended info that identifies this chip. (Presumably a future upgrade might define non-zero values for the extended ID byte.)
