Also, you could try Oleksijs new way of registering board code as a driver, see 5e1fc532538. > +static void configure_uart(void) > +{ > + void __iomem *iomuxbase = (void *)MX6_IOMUXC_BASE_ADDR; > + > + imx6_ungate_all_peripherals(); > + > + imx_setup_pad(iomuxbase, MX6_PAD_LCD_DATA16__UART7_DCE_TX); > + imx_setup_pad(iomuxbase, MX6_PAD_LCD_DATA17__UART7_DCE_RX); > + > + imx6_uart_setup((void *)MX6_UART7_BASE_ADDR); > + > + if (IS_ENABLED(CONFIG_DEBUG_LL)) > + putc_ll('>'); No need to put that in a IS_ENABLED(CONFIG_DEBUG_LL), without it putc_ll() is a no-op anyway. > diff --git a/firmware/Kconfig b/firmware/Kconfig > index 97b7b3c2ee..c2ff51b911 100644 > --- a/firmware/Kconfig > +++ b/firmware/Kconfig > @@ -16,4 +16,9 @@ config FIRMWARE_IMX8MP_ATF > config FIRMWARE_IMX8MQ_ATF > bool > > +config FIRMWARE_CCBV2_OPTEE > + bool > + depends on MACH_WEBASTO_CCBV2 && PBL_OPTEE > + default y This makes the firmware mandatory for compiling this board, right? Can we make this optional so that we can enable the board in imx_v7_defconfig?
