A10-5750M CPU of AMD Lenovo G505S laptop is from the same Richland 15h family as your F2A85M-* , and its' southbridge A76M should be also very similar to what you have: its' Bolton-M3 but there's a relatively small difference between these Bolton and Hudson since they are from the same family of FCH ( https://en.wikipedia.org/wiki/List_of_AMD_chipsets#Fusion_controller_hubs_(F...) ) . Although I don't know why your IOMMU isn't working and why these Raminit problems are happening, its definitely possible to fix them, maybe even by wisely borrowing some of G505S specific source code (comparing the sources and trying to borrow some sources your board might be lacking). In addition, try looking through the mailing lists / board_status reports to find the people who have the same motherboard as you and CC them your e-mails in case they aren't subscribed to coreboot mailing list; maybe they could tell you some useful info: e.g. what if IOMMU and Raminit were working before but got broken by some bad commit; if you'd know that some of this has been working before together with an approximate date, it'd be possible to triangulate the "things-breaking" commit by doing the dichotomy (e.g. it should take just 10 tries to go through 1024 commits and find which one broke it)

hello mike that are great news! it would be nice if this success would benefit the hudson boards (f2a85m-*) too. IOMMU and Raminit(no dual channel) even with microcode are still buggy as hell. But at least this port makes my home workstation as fast and blobfree as possible.
greetings the nekoboi

Please consider AMD Lenovo G505S laptop: all the hardware virtualizations AMD-V / SLAT / IOMMU are fully supported there (although you have to install a microcode update to avoid the possible glitches), no Intel ME / AMD PSP, quad-core CPU, 16GB DDR3 RAM possible, recent build_status report, and there's a cosy community around it and we intend to support it for a looong time - as long as all our G505S last

sounds promissing i will give it a deeper look later. this makes the SNB/IVY platform much more attractive to me. thx for the information.
Be aware there's still an Intel ME requirement for those platforms; while they are old enough that the ME can be significantly reduced, it cannot be completely eliminated.
