enabling lpuart in u-boot on ls1043a for peripheral
I have a question about enabling lpuarts in u-boot for the purpose of communicating with a peripheral device.
i am using the ls1043ardb sdboot as a jumping off point and all I did was enable the fsl_lpuart in the ls1043ardb sdboot defconfig.
I enbled the fsl_lpuart from within menuconfig and i didnt see any other dependencies i needed to enable so i tried to build it and i got the following error
"u-boot-qoriq/drivers/serial/serial_lpuart.c:417: undefined reference to `devfdt_get_addr'"
do i need to enable something else in the defconfig?
