FYI, I just updated this branch. Changes are :

  - rebase on v2.7.0-rc0
  - end of n/w support for linux 4.4. the fgtmac100 now uses 
    the aspeed end of ring buffer bits to be in sync with 
    linux 4.6 
  - rework of ast2500 support to remove duplicated code. I should
    send to mainline shortly for review.

I gave them a quick test with these images:

    https://openpower.xyz/job/openbmc-build/distro=ubuntu,target=palmetto/lastSuccessfulBuild/artifact/images/palmetto/flash-palmetto
    https://openpower.xyz/job/openbmc-build/distro=ubuntu,target=evb-ast2500/lastSuccessfulBuild/artifact/images/evb-ast2500/flash-evb-ast2500

the ast2500 still needs a little hack in uboot which Joel included in 
v2016.07-aspeed-openbmc :
	
	https://github.com/shenki/u-boot/commit/a0ca4ecbeae4ae9632ebc67bf5318dd2ea09c94f

I need to dig that one to add VBAR support the ast2500 qemu guest. 

Cheers,

C.
