kernel: update and enable full 1GB of RAM on Clearfog Base
I had no idea that I need CONFIG_HIGHMEM to be able to even *see* more
than about 750 MB of RAM on this particular ARM CPU, but hey, here it
goes. (At least there was an info message in dmesg.)
Before:
# free
total used free shared buff/cache available
Mem: 769276 47968 407976 269304 313332 438664
Swap: 0 0 0
Now:
# free
total used free shared buff/cache available
Mem: 1029352 49392 894400 43168 85560 913896
Swap: 0 0 0
Also update to the latest stable (our patches are available as cesnet/2020-04-29).
