LS1046ARDB pinmux RCW setting

Hi NXP Team.

We have an External WDT device and the Enable/Trigger line connect to GPIO2_2/GPIO2_03 respectively.

Can we set pinmux in RCW file ? How to do it ?

It is needed to add into the ".rcw" file the following line:

SPI_BASE=2

Please note that SPI cannot be used in this case because SPI_SCK is available only when RCW[SPI_EXT]=0 and RCW[SPI_BASE]=0.

Hi NXP Team.

Theree are another question.

We want to force pull-high or pull-low the Enable/Trigger pins in U-Boot.

Do you have any suggestion for us ?
