This chip is (nearly) identical to the Winbond w25m512jv which is
already supported by Linux. Compared to the w25m512jv, the 'jw'
has a different JEDEC ID.

W25M512JW-IQ (2 x 256M-bit) Serial MCP (Multi Chip Package) Flash memory,
introduces a new “Software Die Select (C2h)” instruction, which we don't
support. I guess you can't access the second die with what we have in
mainline. Or am I wrong? We'll need to add support for multi-die support
if we want to add new multi-die flashes.

My bad, yes only the first die is accessible. I'll post a patch
dropping this id.
