CRS305-1G-4S has a switch chip with an integrated CPU (98DX3236) and like some of the other similar 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.

MikroTik CRS305-1G-4S+IN ======================== CRS305-1G-4S+IN is a 4x SFP+ switch with a Gigabit Ethernet port for management. Specifications: - Marvell Prestera 98DX3236 switch with an integrated ARMv7 CPU - 512 MB DDR3 RAM - UART @ 115200bps - 4x SFP+ - Gigabit Ethernet (AR8033) - 16 MB SPI flash (Winbond 25Q128JVSM) Currently supported hardware: - UART boot (using kwboot) and console - SPI boot, environment and load kernel Planned: - Gigabit Ethernet support Getting binary.0 ================ binary.0 (DDR3 init phase) can be retrieved/extracted from the integrated bootloader on the SPI flash. Then binary.0 can be replaced with the extracted blob.
