Left shifts are not defined in C if they would cause signed overflow,
so these expressions get instrumented, which makes them unusable as
switch values and triggers compile errors when compiling with UBSan.

flags were getting un-initialized memory
it really didn't matter with the flags getting initialized
anyway
But once I added a new flag that didn't explicitly
set or clear the flag at init well here we are
set flags to VP_DEFAULT_FLAGS in viewport_set_defaults()
add the flags variable to the default vp's set to 0
(it was already initialized to 0 by bss, make it explicit)

Allow a clean shutdown to end in either power off or reboot. Add a
new event SYS_REBOOT to signal it and sys_reboot() to trigger the
event. SYS_REBOOT signals a reboot request and should be listened
for alongside SYS_POWEROFF events.

MEM_ALIGN_ATTR should take advantage of cache line alignment on
all native CPUs which define it, not just ARM CPUs. (This could
arguably be done for hosted targets too, but we don't necessarily
know the size of a cache line there.)

Hold "Play" to boot the OF, or boot it from the recovery menu
by holding "Vol. Up". If you had the hosted port installed on your
player before installing the native port, you'll still have to go
through the hosted bootloader.
A couple notes:
- When booting from the menu, the recovery menu disappears, then
reappears before going into the OF.
- You need to hold the play button for like a half second after the
blue light comes on in order to get into the OF.
The recovery appears to be there, but it doesn't seem to be intended
for end users - it just says "Updater V1.1 - Insert TF Pls". I haven't
tested it beyond seeing that it boots, so I'm going to comment it out
for now.

This gets the volume that the path eventually refers to by parsing
the last volume specifier and returning the part of the path after
it (which does not contain any volume specifiers). The initial part
of the path therefore contains everything up to and including the
last volume specifier.

Enables multiboot for the FiiO M3K, Shanling Q1, and Eros Q native port.
Note this requires an up-to-date Rockbox _and_ bootloader.
Usage instructions will (eventually) be found on the wiki:

Searching in volume 0 is necessary for multiboot targets with only
one drive, like the M3K/Q1/ErosQ. Without this the search code will
never look at the redirect file on these targets.
The search bound is configured with a setting MULTIBOOT_MIN_VOLUME,
which defaults to 0, but is defined to 1 for Sansa players so they
keep their old behavior.

There should be no need for any compatibility hacks since this
value was mostly used internally between the SPL and bootloader.
clk_init() was the only user in the main Rockbox binary which
accessed it, but when loaded by the Rockbox bootloader that code
will not be reached since BOOT_FLAG_CLK_INIT is already set.

Removes the SPL's dual boot support code, and removes the dual
boot selection code on the M3K and Q1 since they can now do it
from the main bootloader.

Screenshots of the recovery menu will be useful for documentation.
This can be disabled by turning off HAVE_BOOTLOADER_SCREENDUMP in
the target config file if the bootloader should ever run up against
max size limits.

Basically, there's longstanding bug in Linux with self-extracting
kernels on MIPS which just happened to manifest now on the M3K as
a hang on boot. The fix is applied to the M3K and Q1 since they
both use this type of kernel image.

Calling multiple levels of indirection in a loop slows things down
Really these need to be rewritten to take a start and end address
like most of the rest of the codebase
But this is safer without having test hardware in hand

Replace inline section copy/fill loops with subroutines, which
reduces code size a bit and and handle zero size copies properly.
Remove the cache initialization loop as well. There's no actual
reason for this because the SPL initializes the caches and just
dropping the cache can even be harmful (in this case it wasn't,
because the SPL flushes the whole cache right before calling in).

This is intended for debugging OF kernel boot problems and has

Two helpers (_init_clocktree and _init_uart2) already existed in
the SPL and are copied verbatim from there. The SPL versions are
still present and will be removed when dual boot works from the
main bootloader.
The other two helpers (_cleanup and _load_pdma_fw) are new.

On the bootloader there's no point reserving memory for these,

Using the audio buffer directly is a bad idea because this will
render core_alloc non-functional if load_firmware() writes into
the buffer but then fails, for example on a checksum mismatch.

The implementation of write_bootdata() and get_redirect_dir() was
copied verbatim in two different places, obviously a bad thing for
maintainability. This moves them to a new file multiboot.c as they
are only used for multiboot.

This looks like it was copy-pasted blindly from elsewhere and it
wouldn't even compile, since hosted RoLo is completely different
from native RoLo.

The header format is basic, a variable length list of values
tagged by 4-byte strings. The main application to to allow a
loader to determine the load address of the binary at runtime
instead of using a hardcoded address. But the header contents
aren't fixed and it could be extended for other purposes too.

Adds a loader for the legacy uImage format that is commonly used on
embedded Linux systems. It verifies checksums and supports uncompressed
and gzipped images. Supports arbitrary reader functions to allow the
images to be streamed off any storage device, for optimal RAM use.

This didn't account for partial page reads properly which resulted
in corrupted data. Fortunately, current released bootloaders do not
perform such reads so they don't trigger this bug.

Using an in-memory buffer for the input or output data for 'inflate'

do it, so predefined helpers should be provided.
