MikroTik CRS305-1G-4S Bit board has a switch chip with an integrated Marvell Prestera 98DX3236 CPU. The Bit board variant is added, which has a bigger Macronix flash. Add basic U-Boot, UART and Winbond SPI flash support.

MikroTik CRS3XX-98DX3236 ======================== CRS3XX-98DX3236 is a U-Boot port that supports a series of MikroTik switches based on the Marvell Prestera 98DX3236 switch with an integrated CPU. Common specifications: - Marvell Prestera 98DX3236 switch with an integrated ARMv7 CPU - 512 MB DDR3 RAM - UART @ 115200bps - 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 (internal CPU <-> switch fabric connection) 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.
