Dear "=?utf-8?B?aGFja2x1LnVib290?=",

What exactly are you doing in Linux? Are we talking about user-space
access through a file sytem (and thus block devices) based on the MTD
layer? Or about raw access to the flash devices? Or about in-kernel
code directly accessing some CFI driver routines?

For user space operations on file system level: yes.

Best regards,

Wolfgang Denk
