imx: Add variscite DART-6UL Evaluation Kit
Port for the DART-6UL Evaluation Kit SBC. Based on the variscite
DART-6UL iMX6ULL SoM.
CPU: Freescale i.MX6ULL rev1.1 900 MHz (running at 396 MHz)
CPU: Commercial temperature grade (0C to 95C) at 43C
Reset cause: POR
Model: Variscite DART-6UL Evaluation Kit
Board: Variscite DART-6UL Evaluation Kit
DRAM: 512 MiB
MMC: FSL_SDHC: 0, FSL_SDHC: 1
In: serial@02020000
Out: serial@02020000
Err: serial@02020000
Net: FEC0
Working:
- Eth0
- i2c
- MMC/SD
- eMMC
- USB host
- UART 1
Note: LCDIF porting needs DM_VIDEO
