This commit adds initial support for the Toradex Apalis iMX8X 2GB WB IT V1.1A System on Module support [1]. Boot log: U-Boot 2020.10-02940-g894aebb7e8-dirty (Oct 22 2020 - 09:43:57 +0300) CPU: NXP i.MX8QXP RevB A35 at 1200 MHz at 30C DRAM: 2 GiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 Loading Environment from MMC... OK In: serial@5a070000 Out: serial@5a070000 Err: serial@5a070000 Model: Toradex Apalis iMX8 QuadXPlus 2GB Wi-Fi / BT IT V1.1A, Serial# 06617018 Net: eth0: ethernet@5b040000 [PRIME] Hit any key to stop autoboot: 0 Functionality wise the following is known to be working: - eMMC and MMC/SD card - Ethernet (*) - GPIOs - I2C Unfortunately, there is no USB functionality for the i.MX 8QXP as of yet. * With the SCU FW from the latest Toradex BSP 5.0.0 (SCU FW 1.5.1) ETH PHY encounters bring up problems after reset, this will be fixed soon on SCU FW side.
