BIOS firmware on ARM

Intel have ME,AMD have PSP,what does the ARM have and how much depends on its architecture type and vendor?
This is not clear to me,as i could see most of their BIOS are short and do not have many options like on x86 and/or its not made to be accessed on such way.
Can someone explain me this thematics,for example would i be more secure with newest AMlogic or Rockchip or Allwiner and similar boards(CPU/GPU) rather than newest intel/amd chipesets?
Regards and have a nice day.
Depend on ARM chip but if you talking for dev boards AMlogic or Rockchip or Allwiner then yes.
I think big problem is now in sofware cos if we talking for security linux kernel is very big and very small number of
people can understand it even is open source.
In my humble opinion, lack of understanding of the Linux kernel is probably not the biggest issue- ignorance in Chinese industry regarding free software seems to be far more of a problem, especially with the proliferation of non-upgradeable devices.
I think that both problems are equally important.We can all see bunch of software devs in youtube videos,but how much of those people are firmware developers that create WiFi chip drivers,graphic card drivers etc.It is extremely rare to find even one that work on OpenSource/Libre branch and those that work on proprietary drivers, its like they live on another planet.
Now non-upgradeable chips,this is double edge sword.As more quality comes from soldered components( i mainly refer to the RAM)but i think that there should be some way of expansion.On x86 i would quite often run on the BEEPing RAM problem if i would try to replace the RAM.Its just something that is meant to break,compared to the old catridge based consoles.<

I am not speaking in terms of having availability to have expansion board.I was referring to standard desktop usage compared to AMD and Intel.I will write more about AMD machines that i have and why i don't like it.
Yes i see EOMA68 as a great idea,but for example if i would buy some of the boards from the above, how much endangered would i be compared to the AMD psp and Intel ME technologies that they have?

ARM SoCs don't have any of the same problems as CPUs from Intel and AMD. They typically include non-essential components (typically wireless and GPU hardware acceleration) which require blobs, but otherwise can work with an entirely libre software stack.
The usual problem with ARM SoCs is that they don't work with mainline Linux; they instead need a specific modified Linux. I'm not familiar with Linux development, so someone who is can correct me if I'm wrong, but the impression I get is that this is caused mainly by use of kludges that Linus Torvalds is not interested in merging into mainline Linux for obvious reasons, and secondarily by many companies violating the GNU GPL when they develop these custom versions of Linux.
