IIRC y stands for "yes", assuming support is in the kernel, and y is to 
enable that support. I think you are correct that m is for "module".

Have you tried UART connection?

Before arch linux arm supported the A10 olinuxino-lime, I got u-boot and 
a kernel compiled with an arch linux rootfs, to put on an sdcard [1]. I 
also did the same for an A13 tablet (although it had/needed proprietary 
wifi drivers).

It was a long time ago, but I also had problems, so debugged using UART, 
and can strongly recommend this for sunxi devices.

That said, I did not use libreboot, I used u-boot instead. Somebody had 
already ported u-boot to those boards, so not much work was needed.

Sorry if I cannot be of any more help, I am by no means an expert,

Nowadays, I just install the arch linux arm image, and follow the 
migration guide, which doesn't help much for debugging, but seems to work.
