new commands: uuid and guid - generate random unique identifier
Those commands basis on implementation of random UUID generator version 4 which is described in RFC4122. The same algorithm is used for generation both ids but string representation is different as below. char: 0 9 14 19 24 36 xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx UUID: be be be be be GUID: le le le be be Commands usage: - uuid [<varname>] - guid [<varname>] The result is saved in environment as a "varname" variable if argument is given, if not then it is printed. New config: - CONFIG_CMD_UUID Signed-off-by: Przemyslaw Marczak <p.marczak@samsung.com> Cc: Stephen Warren <swarren@nvidia.com> Cc: Lukasz Majewski <l.majewski@samsung.com> Cc: trini@ti.com
