[U-Boot] [PATCH v2] arm: zynq: Add support for DLC20 board

Michal Simek michal.simek at xilinx.com
Tue Oct 2 06:49:03 UTC 2018 

Xilinx DLC20 has I2C0 with EEPROM(1KB), UART1, GPIO, SD0 (EMMC 4GB),
USB0 device, ENET0, QSPI (16MB) and DDR(two of 256MB each).

Boards have mix of Winbond/ST QSPIs.

Changes in v2:
- zynq7000
- mmc fixed
- Enable also qspi winbond with ST
