Board: Pi2B
A few quick questions (Béla?) regarding the Pi:
1) According to the overlay (tree) README document, please see the notes on act_led_gpio as the default pins. On non-plus boards the default is listed as 16, on B+ and above, 47?? Based on the 10-key, was this a typo intending to be GPIO 17? (Pin 13)
2) The file 6.1alpha4_v7.gz is assumed to be the init image. Is it safe to assume it's a compressed CPIO file as is with x86/64?
3) If I leave SPI and I2S disabled and enable I2C, can the SPI pins be used as standard GPIO bits? (I assume so, but have read conflicting stories online.) I'll have limited I/O until my I2C boards arrive in the mail, so I'm looking to drive a couple separate 20x4 LCDs (4-bit mode) and a 16 channel relay board (16 bits) so I'm a few I/O short otherwise :)
4) Finally, I have not ripped into the boot image yet, but is it set up in the same fashion that the x86 version(s) are? (ie: /etc/init.d/tc-config being the initial boot/configuration file, etc.) I have a few things which will need to launch at the very beginning of the boot process, so if set up in a similar fashion this should be almost effortless!
Thanks in advance and take care!

1) Open a GitHub ticket
2) yes
3) Don't know, try
4) Picore base is built on the same set of scripts as x86/x86_64 versions and boots the same way.
