Hello,
Although I fear already knowing the answer to my question I'm asking anyway who knows may be someone will have a good answer
Is there a standardized list of addresses corresponding to all GPIO on boards ?
If so where there find , otherwise what is the best way to find it for you?

Not really - different vendors tend to use different memory maps and different peripherals, although standard firmware libraries such as CMSIS can hide some of those differences.

I'd start with the chip vendor's TRM for the specific device you are using,

That's what i think... As you want, i use a lot of dev board. For exemple a Beaglebone Black, or an OMAP5432 uEvm.
Maybe for the Ti arch i could use PASM with PRU instead of linux-gnu-as ?
Isn't this what all the device tree support work is about, to stick a standard description of the devices on a board into the boot rom so any later code can use them without having to have constants built in? Linus Torvalds had a rant about this very point a couple of years ago and it is one of the jobs Linaro has done a lot of work to solve.
I understand what you mean. But it could be util to set a standard that board designers could follow ? There are many creative and linaro brought a lot of tools , but I think it will allow an encoding and optimized code optimization for embedded software drivers?
