How to set the I.mx6Q uart baud rate on the mx6q_sabresd default configuration while playing the MCIMX6Q-SDB Board?

[JustinWu2]

Dear all:

How to set the I.mx6Q uart  baud rate to 115200 on the mx6q_sabresd default configuration while playing the MCIMX6Q-SDB Board?

The following is my console messages.

Serial: IMX driver

imx-uart.2: ttymxc2 at MMIO 0x21ec000 (irq = 60) is a IMX

imx-uart.0: ttymxc0 at MMIO 0x2020000 (irq = 58) is a IMX

Serial: Console IMX rounded baud rate from 114943 to 114900

Best Regards,
