CONFIG_CMD_SF
|

|
|

|
Defining this option enables SPI flash commands
|
||||||
|
'sf probe/read/write/erase/update'.
|
||||||
|
|
||||||
|
Usage requires an initial 'probe' to define the serial
|
||||||
|
flash parameters, followed by read/write/erase/update
|
||||||
|
commands.
|
||||||
|
|
||||||
|
The following defaults may be provided by the platform
|
||||||
|
to handle the common case when only a single serial
|
||||||
|
flash is present on the system.
