Rockchip, Marvell, AMD (barely an ARM manufacturer, but SoftIron sells them), Cavium (mostly on super-expensive servers though)

Pretty sure Rockchip has violated Linux's GPL. Rest of who you listed I've never seen/used in real life.

  Maybe a very long time ago. Or you're confusing them with Allwinner. Rockchip has the source of all the things on their GitHub, and a ton of commits in mainline Linux.

  You've never heard of amd?

  I think they did, but I'll take GPL violations and (possibly leaked?) publicly available documentation over GPL-compliant source code dumps (which are next-to-useless for actually understanding the hardware anyway.)

    > possibly leaked Not leaked, entirely official: http://opensource.rock-chips.com http://opensource.rock-chips.com ("Hardware Support" section) And instead of dumps, they have proper git commits! https://github.com/rockchip-linux/kernel/commits/release-4.4 https://github.com/rockchip-linux/kernel/commits/release-4.4 And lots of upstream linux commits with @rock-chips.com addresses.

      Interesting. The docs I found before were marked "Rockchip Confidential". But the ones on their site are not complete either --- the fact that only "Part1" of the TRM is there suggests that there is a 2nd part (and possibly more.)

        Yeah, I've seen the "confidential" mark on the same documents (or older versions) — these were published on board vendors' sites (e.g. Pine64's). Not sure what would be in a "secret 2nd part"… the only thing I can think of that's missing from "Part1" is the display system. But there is a driver in mainline Linux for that https://github.com/torvalds/linux/blob/master/drivers/gpu/drm/rockchip/rockchip_drm_fb.c https://github.com/torvalds/linux/blob/master/drivers/gpu/dr...

Marvell? really?
