Indigo release incompatible with certain Pi 1 models

[hoglet67]

This was picked up by JGH and just replicated by myself.

The Indigo release doesn't work properly on certain Pi 1 models.

Here's a list of all known Pi 1 Models:

It works correctly on Revision 0002 (the original Pi B 1.0 256KB model)

Ir doesn't work correctly on Revision 000F (the {Pi B 2.0 512KB model)

I think the Pi B 2.0 has a slightly different GPIO pin assignment, see: https://www.raspberrypi-spy.co.uk/2012/06/simple-guide-to-the-rpi-gpio-header-and-pins/

Here are some boot logs: board_2.txt board_f.txt

Looking at the DEBUG_GPU stuff at the start, R3 is the same in both cases, and it shouldn't be.

I think this commit broke things: b487abbb

I'm going to attempt to fix this now.

That commit also broke the activity LED on the Pi 1 models.

It relies on the firmware inserting the bcm2709.disk_led_gpio property into the command line properties.

That doesn't seem to work on the Pi 1 Models I have.

Not sure if this is a regression with the newer RPI firmware blob we are using, or whether this has never worked.

l've fixed this as well.

Dominic, do you recall which original Pi models were not working, that b487abb fixed? I want to make sure I haven't caused any further regressions.

I don't recall. I'm afraid. Sorry about the regression.
