Subject: cfi_flash: Add interface for flash verbosity control
X-Git-Tag: v2009.01-rc1~66^2~1
X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=6ea808efdf9aa5d9067fbfac32acde8539129ed2;p=u-boot

cfi_flash: Add interface for flash verbosity control

Add interface for flash verbosity control. It allows
to disable output from low-level flash API. It is useful
when calling these low-level functions from context other
than flash commands (for example the MTD/CFI interface
implmentation).
