Subject: [PATCH] no buffered write in m28w320cb
Date: Thu, 19 Feb 2004 16:24:25 +1300 [thread overview]
Message-ID: <40342C69.9050100@tait.co.nz> (raw)
[-- Attachment #1: Type: text/plain, Size: 421 bytes --]
Like the m28w320ct, the m28w320cb does not support buffer writes.
This patch to cfi_cmdset_0001.c treats them the same by disabling the
timeout value for m28w320cb devices to turn off the buffered write feature.
