I don't have any SA1100 devices, I only have a couple of SA1110 Assabets.
I've just tested 4.8.0-rc2 there, and it boots, although cpufreq appears
a little unhappy.

Make sure you have "console=ttySA0,38400n8" or similar to get serial
console output - it needs to be a "ttySA" port, not "ttyS".

Same probably goes for "earlyprintk=serial,ttyS0,115200", although I've
no experience of earlyprintk myself.  However, if you're not even
getting the "Uncompressing Linux... done, booting the kernel." line,
that suggests the decompressor is not running, or is trying to access
the wrong serial port.  The decompressor tries to find the first serial
port out of serial 3, 1 and 2 which has been left enabled.

Hope this helps.
