[U-Boot] [U-boot][PATCH v3 06/14] board: atmel: Add sam9x60ek board

Fri Sep 27 13:08:52 UTC 2019

From: Sandeep Sheriker Mallikarjun <sandeepsheriker.mallikarjun at microchip.com>

Add new board SAM9X60-EK using the ARM926 SAM9X60 SoC.

Signed-off-by: Sandeep Sheriker Mallikarjun <sandeepsheriker.mallikarjun at microchip.com>
[tudor.ambarus at microchip.com:
- fix number of DRAM banks:
  One DDR2-SDRAM (W972GG6KB 2 Gbit = 16 Mbit x 16 x 8 banks]
- drop SPL related macros
- drop memtest macros
- drop CONFIG_SPI_BOOT, CONFIG_SYS_USE_DATAFLASH related macros
- drop inclusion of asm/arch/at91sam9_smc.h]
