The DCD table for u-Boot of iMX28_Linux BSP

Dear all,


Our customer changed the following pin into the PWM output in the original board.

L7 pin => PWM1
K8 pin => PWM2


However, a pulse signal is outputted from these pins during the Boot.


On a MX28EVK of Freescale, these pins are DUART_TX and BACKLIGHT_PWM.
Their BSP is based on Linux_BSP of Freescale.


I think that they need to change a setup of these pins in U-Boot.

I understand that such a setup is performed by DCD table.

However, I was not able to find DCD table in Freescale Linux_BSP.


Would you teach the place where DCD tabel is indicated who sets up these pins?


Best regards,
