This Openwrt fork is intended to add support for the MIPS Creator CI20 board.

The status, for now, is as follows:

Working (at least seems to be):

• IRQ controller.
• DMA controller.
• Pinctrl.
• NEMC (nand and external memory controller).
• Davicom DM9000 ethernet.
• TCU and CGU.
• OHCI usb.
• DWC2 OTG USB.
• RTC controller.
• ACT8600 power regulator.
• I2c bus.
• MMC driver.
• Video.

Not workinkg:

• Wifi (brcmfmac): the driver does not properly detect the wireless module.
• EHCI usb.
• Audio: driver problem (wip).

Still not tested:

• NAND flash.

To be added:

• FUSE driver.
• Code to show the CPU, L2CACHE, DDR and AHB clocks at bootup like kernel 3.0.8 does.

How to boot the MIPS Creator CI20 with OpenWRT (for now):

• 1. Make a bootable memory card with an ext4 partition.
• 2. Inside the memory card first partition create a directory called "boot",if it does not exist, and copy vmlinux.img on it.
• 3. Copy OpenWRT rootfs into the MMC card.
• 4. Power on the board and test.

Notes:

• Some drivers need to be improved (WIP).
• Despite the ethernet controller is attached to an "slow" internal memory bus, the performance is good (~ 75 Mbps) with kernel 3.18 and above.
