From: Goran Rađenović <gradenovic@xxxxxxxxxxxxxx>
Add support for Ultratronik's stm32mp157c fly board. This board embeds
a STM32MP157c SOC and 1GB of DDR3. Several connections are available on
this boards: 2*USB2.0, 1*USB2.0 MiniUSB, Debug UART, 1*UART, 1*USART,
SDcard, RJ45, ...
This patch enables basic support for a kernel boot - SD-card or eMMC.
