From 96ef831f713289afba19da0c8f905e99da2b23e0 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Thu, 3 Apr 2008 13:36:02 +0200 Subject: cfi_flash: Support buffered writes on non-standard Spansion NOR flash Some NOR flash chip from Spansion, for example, the s29ws-n MirrorBit series require different addresses for buffered write commands. Define a configuration option to support buffered writes on those chips. A more elegant solution would be to automatically detect those chips by parsing their CFI records, but that would require introduction of a fixup table into the cfi_flash driver.
