History

Luka Kovacic 22bb913fdf arm: mvebu: Add CRS305-1G-4S board 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.
