The RZ/N1 is a family of SoC devics from Renesas, featuring:
* ARM Cortex-A7 CPU (single/dual core) and/or Cortex-M3 * Integrated SRAM up to 6MB * Integrated gigabit ethernet switch * Optional DDR2/3 controller * I2C, SPI, UART, NAND, QSPI, SDIO, USB, CAN, RTC, LCD
Add basic support in the form of ARCH_RZN1 symbol.
