Mostly just a few warnings where things are promoted via passing floats to
printf. Those we should generally remove anyway because they're just
benchmarking code. Most things LK runs on either doesn't have float or
doesn't have double sized floats.
Some of the structures, notably 'cmd', in the lib console stuff are a
little too generically named and have collided with some other code
so prefix the names a bit more cleanly with console_
The change is largely mechanical, and folks with out of tree code can
easily switch by renaming:
cmd -> console_cmd
cmd_args -> console_cmd_args
cmd_block -> console_cmd_block
console_cmd -> console_cmd_func
Apologies if this breaks you but it should be pretty easy to fix.
This lets some arches return a 64bit counter.
As a result of fixing this, removed -Wno-format switch in the test app
which caused the need to fix a lot of printfs.
Now you need to include arch/atomic.h to get to the atomic routines.
This simplifies a recusion issue in the way arch/ops.h included
arch_ops. Also just generally makes things cleaner.
TL;DR most uses of lib/console.h -> lk/console_cmd.h
Move the part that lets a piece of code somewhere in the system to
define a console command from the actual lib/console api to start an
instance of the console. Move in almost every place the user of the
console command definition to the new header, lk/console_cmd.h which is
always in the include path.
Also remove most uses of testing for WITH_LIB_CONSOLE since you can
almost always just safely define it and then let the linker remove it.
Almost nothing changes here except moving braces to the same line as the
function declaration. Everything else is largely whitespace changes and
a few dangling files with tab indents.

Currently targets qemu's sifive_e machine, which is a split flash/ram
machine, much like the Sifive HiFive1. Untested as of yet on a real
HiFive1.
Basic support including interrupts and architectural timers in place.
Most of the warnings are new, such as needing to mark fallthroughs on
cases explicitly. A few are based on signed vs unsigned comparisons.
Disable one warning that was annoying about comparing null to arguments
marked nonnull.
Previously, if tail was == 0, and we wrote exactly enough bytes to
the end of the buffer, then head would end up at 0 as well. This
would make the buffer instaneously empty, as head == tail.
Ran everything through scripts/codestyle.space, which uses astyle
to generally follow K&R style.
Biggest non whitespace change is pulling brackets down on function
declarations, which I'm pretty ambivalent about, but astyle insists
on taking a stance
This picks up the major work of allowing multiple heap implementations
and enable dlmalloc as an alternate heap to the simple existing one
(now called 'miniheap').
Also added a novm page allocator for memory management on systems too small
or missing an mmu to have a vm. Not much more than a simple bitmap allocator
that the heap pulls from. Allows for other heaps and/or users of physical
memory to coexist and span multiple banks of memory.
-Add more interesting names to fibo threads
-Iterate a lot more on some of the thread tests (for faster cpus)
-Add spinner command that lets you add threads that spin forever
