arm: mvebu: Convert CRS305-1G-4S board to CRS3xx-98DX3236
Convert the CRS305-1G-4S board to CRS3xx-98DX3236 to enable easier
implementation of new CRS3xx series boards, based on Marvell Prestera
98DX3236.

+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.

+WARNING:
+--------
+This file should contain the bin_hdr generated by the original Marvell
+U-Boot implementation. As this is currently not included in this
+U-Boot version, we have added this placeholder, so that the U-Boot
+image can be generated without errors.
+
+If you have a known to be working bin_hdr for your board, then you
+just need to replace this text file here with the binary header
+and recompile U-Boot.
