CRS305-1G-4S has a switch chip with an integrated CPU (98DX3236) and like some of the other simillar boards requires bin_hdr. bin_hdr (DDR3 init stage) is currently retrieved from the stock bootloader and compiled into the kwb image.
Adds support for U-Boot, enable UART, SPI, Winbond SPI flash chip support and writing env to SPI flash.

- 512 MB DDR3 RAM
- UART @ 115200bps
- 4x SFP+
- Gigabit Ethernet (AR8033)
- 16 MB SPI flash (Winbond 25Q128JVSM)

- UART boot (using kwboot) and console
- SPI boot, environment and load kernel

- Gigabit Ethernet support
