This only required a minor patch to the usb-designware driver due
to DMA requiring physical addresses -- on the X1000, these differ
from virtual addresses so we have to do the usual conversion.
Both the mass storage and HID drivers work, but there are a few
issues so this can't be considered 100% stable yet.
- Mass storage might not be detected properly on insertion,
and USB has to be replugged before it shows up
- HID driver may occasionally panic or hang the machine

SPL is now designed so core X1000 code is in control of the boot,
under the reasonable assumption that the device boots from flash.
It should not be too hard to adapt to other X1000 ports.
The biggest functional change is that the SPL can now read/write
the flash, under the control of a host computer. The SPL relies
on the boot ROM for USB communication, so the host has to execute
the SPL multiple times following a protocol.

Inline assembly in RoLO and the FiiO M3K bootloader used 'jr' to
jump to a newly loaded Rockbox binary, but incorrectly left the
branch delay slot open. That gives GCC an opening to place illegal
instrutions, etc, which might cause an unhandled exception.

After reviewing the code awhile I realized that the failsafe and hold
switch have no impact on the boot process when the usb or charger is
connected. That makes no real sense to me. If these are connected then
neither will be used at all. The boot process will never revisit it
either once those other modes end and resume the boot process. It will
just continue to try to boot from disk as if these emergency settings
never existed.
I have decided it makes more sense for them to be evaluated once the
higher priority charge and disk mode have finished their roles. Given
how the code was originally written it seems to be they were not
intended to run prior to these at the very least since the logical
conditions preclude that possibility as they include the inverse of
the conditions that trigger the charge and disk modes.

This fixes an early boot bug on the h300 where hold_status is
read before it has a chance to properly check whether the hold
switch is even active. This was accomplished by porting over
the method the h1x0 uses to perform the same check.

This saves a few bytes of precious space by consolidating paths where
they can be combined with no change to the underlying algorithm.

The most major change here is the porting of the failsafe boot
menu and eeprom settings support from the h1x0 bootloader to the
h300 bootloader. This has been successfully tested already and
indeed works about the same as it does on the h1x0 bootloader.
The other major change is the addition of new code to both
bootloaders that will retry the flash boot function after
exitting disk mode. It still falls back to booting from disk
if this either fails or is not configured to boot from flash.
There were also various other modifications to bring the two
closer in sync so there are fewer differences.

First this removes most of the conditionals for the CPP as they
are always true for the targets that use the bootloader source.
Second this moves some global variable references around to reduce
some redundancy in the h1x0 bootloader source.
All of this is done to make it easier to compare the two bootloaders
as they are very heavily related to each other.

This enables USB charging when the bootloader is in charge mode or
disk mode. As a byproduct there is a small change in behavior where
charge mode is all that is available if it is triggered by the USB
cable insertion. Disk mode only becomes available if the user requests
to continue the boot process by pressing the power button. It had to be
done this way as there's no way to tell this early whether the user
wants to simply charge or trigger disk mode as well.

* HOME_DIR is now either "/" or special "<HOME>"
* target-specific "home dir path" is defined solely by PIVOT_ROOT
* PIVOT_ROOT path is now defined in toplevel config files
* Make Samsung YP-R0/R1 and SONY_NWZ use PIVOT_ROOT too
* Do not prepend PIVOT_ROOT path if the path already has it!
* Do not play these games for __PCTOOL__ builds

The Q and K have a slightly different case, but the hardware under the
shell is completely identical.
These models are rebadged versions:
* Hifiwalker H2 (== Q)
* AGPTek H3 (== K)
* Surfans F20 (== K)
Other notes:
* Significant improvements in the shared Hiby-platform launcher/loader
* SD card can theoretically be hot-swapped now
* Support external USB mass storage!
* Some consolidation of Hiby-platform targets
* Some consolidation of plugin keymaps
Todo/known issues:
* Keymaps need to be gone over properly
* Convert to HAVE_SCROLLWHEEL?

X3II confirmed working by forum tester, X20 is nearly identical.
This includes bootloader, main firmware, and the flash image patcher.
Eventual Todo:
* Further refactor AGPTek Rocker & xduoo hiby bootloaders

NOTES:
- bootloader makefile convert an extra font to be installed alongside the bootloader
since sysfont is way too small
- the toolsicon bitmap comes from the Oxygen iconset
- touchscreen driver is untested
TODO:
- implement audio routing driver (pcm is handled by pcm-alsa)
- fix playback: it crashes on illegal instruction in DEBUG builds
- find out why the browser starts at / instead of /contents
- implement radio support
- implement return to OF for usb handling
- calibrate battery curve (NB: of can report a battery level on a 0-5 scale but
probabl don't want to use that ?)
- implement simulator build (we need a nice image of the player)
- figure out if we can detect jack removal
POTENTIAL TODOS:
- try to build a usb serial gadget and gdbserver

Many includes of fat.h are pointless. Some includes are just for
SECTOR_SIZE. Add a file 'firmware/include/fs_defines.h' for that
and to define tuneable values that were scattered amongst various
headers.
Remove some local definitions of SECTOR_SIZE since they have to be
in agreement with the rest of the fs code anyway.
(We'll see what's in fact pointless in a moment ;)

For some reason, the bootloader and config files didn't define
HAVE_BOOTLOADER_USB_MODE, also remove the special cases in usb.c which they
implied.
