Add gettime command
Gettime returns the current timer value. If CONFIG_SYS_HZ is defined then the timer value is also converted to seconds. Tegra20 (SeaBoard) # gettime Timer val: 7754 Seconds : 7 Remainder : 754 sys_hz = 1000 There has been some discussion about whether this is useful enough to be included in U-Boot. The following boards do not have CONFIG_SYS_HZ defined: M52277EVB M52277EVB_stmicro M53017EVB M54418TWR M54418TWR_nand_mii M54418TWR_nand_rmii M54418TWR_nand_rmii_lowfreq M54418TWR_serial_mii M54418TWR_serial_rmii Signed-off-by: Anton Staaf <robotboy@chromium.org> Signed-off-by: Simon Glass <sjg@chromium.org>
