Hardware:
SoC: SAMA5D29 500 MHz
DRAM: LPDDR2 512 MiB
PMIC: MCP16502
Debug: UART0
Flash: QSPI NOR 8 MiB
RGB LCD connector
Mikrobus connectors x 2
SD-Card connectors x 2
USB 2.0 x 2
Changes in v2:
* Remove CONFIG_SYS_PROMPT and CONFIG_SYS_PROMPT_HUSH_PS2
* Remove CONFIG_SYS_SDRAM_BASE and CONFIG_SYS_SDRAM_SIZE
