Hi Andreas,

When trying to boot 3.13 with the attached .config in aranym I get a
panic during init_bootmem_core once I try to set FastRAM to anything
bigger than 256. With 3.12 and pretty much the same config I could go
up to 932 while still having enough room in ST-RAM for the frame buffer.
The static kernel size only grew by about 45k.
Can you please post the panic message?
There are actually two types of panics, one with CONFIG_KEXEC, the other
without it:

At first sight, I don't see a relevant difference with the .config I'm using.
Did the kernel size grow above 4 MiB? If not, can you please bisect?
The size is 4089118 vs. 4135192, so still below 4M, though already
pretty close.
Andreas.
