All, This is a work in progress. All mistakes are mine. Seriously. I've never touched omap before. It should be obvious. History: The Wireless Plus is a portable, 1TB HD with an ~ 4 hour battery, and a wifi hotspot. It's only external connection is the SATA port (GoFlex connector). The Wireless Plus is the successor to the GoFlex Wireless. Full source can be found here [1] (GoFlex Wireless). These appear to be exactly the same at the hardware level. The primary difference is drive capacity, and the Wireless Plus exposes uart1 to an unpopulated header in the corner of the board, so I chose to develop on it. :-) Technical: Both boards are using an AM3703 SoC and the tps6507x power regulator/battery charger. Both are using the Hynix h8kds0un0mer-4em RAM module. Status: The following patches are a work-in-progress and are based against v3.9. It basically boots (to rootfs panic) with patches 1 and 2. The gpmc patch oops out. I've included it in the hopes that someone can laugh at me and maybe give me a pointer. I need it to work in order to add the child node for the nand, and then the child nodes for the partitions. Tony has been helping me out offline with this, and he suggested trying the gpmc against Linus' ToT. Which locks up before it even has a chance to get going. So this series is against v3.9. The current state of the dts file has been to silence warnings/errors. I disabled a bunch of unused devices, and added the pinctrl nodes in order to remove the pins not found kind of errors. As for their correctness, I haven't been able to test yet. I've done a liberal amount of copying from the provided sources for u-boot and the kernel. If you're motivated, grepping those sources for 'satellite|vavni' locates most of the changes made by Seagate. Current Problem: There are several gaps in my understanding of how far along TI's conversion to DT is. Should I be doing a separate board file for initializing the legacy items? I was hoping to do it all with DT. Obviously, I don't expect anybody to run out and buy one of these, take it apart, and try to boot this code. But if the omap guys could take a look at this and give me a few pointers, I'd appreciate it. I'm kind of spinning my wheels at the moment. Primarily, I'd like to get nand and usb working, so that I can read/write, mount a rootfs and do better testing. thx, Jason.
