Tim Harvey 6fc639461b board: gateworks: venice: enable SPL_DM_SERIAL
The uart2 and its pinmux are already marked with u-boot,dm-spl but we
need to move the call to preloader_console_init() after spl_early_init()
to avoid a board hang as dm can't be used until after spl_early_init()
due to the uart driver not enabling the uart clock.

Remove the manual config of the UART pinmux now that it is no longer
needed.

U-Boot for the Gateworks i.MX8M Mini Venice Development Kit boards

Quick Start
===========
- Build the ARM Trusted firmware binary
- Get ddr firmware
- Build U-Boot
- Flash to eMMC
- Boot

Get and Build the ARM Trusted firmware
======================================
$ git clone https://source.codeaurora.org/external/imx/imx-atf
$ git checkout imx_5.4.47_2.2.0
$ make PLAT=imx8mm CROSS_COMPILE=aarch64-linux-gnu- bl31
$ cp build/imx8mm/release/bl31.bin .

Get the DDR Firmware
====================
$ wget https://www.nxp.com/lgfiles/NMG/MAD/YOCTO/firmware-imx-8.9.bin
$ chmod +x firmware-imx-8.9.bin
$ ./firmware-imx-8.9.bin
$ cp firmware-imx-8.9/firmware/ddr/synopsys/lpddr4*.bin .

Build U-Boot
============
$ make imx8mm_venice_defconfig
$ make CROSS_COMPILE=aarch64-linux-gnu-

Update eMMC
===========
=> tftpboot $loadaddr flash.bin
=> setexpr blkcnt $filesize + 0x1ff && setexpr blkcnt $blkcnt / 0x200
=> mmc dev 2 && mmc write $loadaddr 0x42 $blkcnt # for IMX8MM
=> mmc dev 2 && mmc write $loadaddr 0x40 $blkcnt # for IMX8MN
