Here is my updated tree with a lot of cleanups and various small fixes : https://github.com/legoater/u-boot/commits/v2016.11-aspeed-openbmc These are required before sending mainline, last remaining hack being : https://github.com/legoater/u-boot/commit/50812645a37b067a7346a924da3e9e0bc1d29eb9 The network driver are not strictly needed for mainline but we need to do something for the flash driver soon. This is very very custom today. So I added the Linux dts as we could use them for a spi-nor driver in U-boot. The dtb just needs to be in the flash image. For that you can use the linux compiled one and dd it at the end of the u-boot partition at 0x20050000 and start hacking. Cheers, C.
