d83bcc643e add wifi firmware, move things around in ram 
* at the base address we were using, the filesystem was getting
corrupted presumably because the kernel unpacked into it

* leave a little more space between compressed kernel and
squashfs. this is probably ineffective but also harmless

e0ea576674 rename "device" config tree as "hardware" 
we are also using "device" for "network device" (as in eth0,
wlan0 etc) so this makes it a bit less confusing perhaps

`config` (e.g. pathname to DTS) that can later be overwritten
(even by the end user)

f1b7780537 speed up kernel build 
by having two separate derivations for patching the kernel source tree
and building it, we have to copy said source trees from one store
location to another which takes non-neglible time on spinning rust
(literally minutes on my machine). Replace with a single derivation
that can do more things on one tree in-place

e823e7a29c HALFARSED enable toggling promptless kconfig symbols 
Some kernel config symbols we need to enable in some configurations
don't have a "prompt" entry in the Kconfig files, meaning that
make oldconfig (or any other make fooconfig) won't change them.
So we add a Kconfig.local where they can be selected

In this patch we hardcode the required symbol. Next step would be
to generalise so that they could be specified in something like a
config.kernel.hiddenConfig attrset
