Added images of pinout and location of BIOS flash chips on ODROID H4

I found the recovery section quite confusing, added an image of the flash chips' location and their pinout.

It should be enough to keep the HOLD and WP pins floating, no need to pul lto 3.3V? Or was it required here? IIRC most of our setups simply keep then not connected.

I know these are not yours changes but you could also try to fix the links: https://github.com/Dasharo/docs/actions/runs/29832840539/job/88641587572#step:3:430

I think they can be mostly removed. The KGPE flash chip is no longer offered in our shop.

Just to be safe I've replicated the diagram provided here (it's the same chip as H4):

That said it did indeed work just fine with those pins left floating.
