The Q1 handles firmware updates by unpacking the firmware image
from the player app, then rebooting into the recovery kernel.
The recovery kernel reflashes the player kernel and rootfs with
the unpacked update files on the SD card.
Booting the recovery kernel directly is therefore not useful to
the vast majority of users; remove the option from the recovery
menu and remove the key combo.

It's now possible to install OF updates on a rockboxed Shanling Q1.
Previously these didn't work because the RB bootloader interrupted
the update process.
Updates will proceed as they normally do on a non-Rockboxed Q1,
except at the end of the update you'll reboot to Rockbox instead
of the OF. This is only a minor inconvienience and doesn't affect
the update process.

There is actually no need to parameterize most commands with row
or column cycles, usually the opcode and row/column address width
are linked. When this is not the case we can use raw SFC commands
or define new macros.

Update the uimage reader's bad block handling to treat an ECC
uncorrectable error on the first page of the block as a bad block.

Using 'typedef struct' is not in line with the project coding style
and somewhat problematic, so get rid of it here.

The flash probe mimics the boot ROM's flash read routines and
dumps the manufacturer & device IDs and 16-byte parameter data
to a file on the SD card.

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.

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.

Bad blocks in a kernel flash partition seem to be handled by skipping
ahead to the next block; this is a common bad block management scheme
for simple software like bootloaders (and is the default method for
reading NAND partitions in u-boot).
Extend the uImage flash reader to skip bad blocks while reading.

Add a debug menu to invoke two new actions, dumping the OF kernel
and recovery images from flash to the SD card.

The M3K's kernel has an incredibly stupid function that mangles the
kernel args and copies them to a 100-byte buffer without any kind of
bounds checking. So, if the kernel arguments are more than 99 chars
the stack may be corrupted, sometimes crashing the kernel.
Fortunately, most of the arguments the OF uses are useless, and the
truly necessary arguments fit within the absurd 99-char limit.

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.

This adds a *very basic* Linux loader to the Rockbox bootloader,
which allows running a mainline Linux kernel using the following
file layout on the SD card:
- /uImage
- /linux_cmdline.txt
The command line arguments are listed in linux_cmdline.txt, all
lines are concatenated together and whitespace is converted into
spaces. Comments aren't supported however.
The loader doesn't support the modern devicetree boot protocol,
so it can only pass command line arguments. It would be easy to
support an appended dtb though.

Adds the ability to boot the OF's player or recovery kernels
from the bootloader. Works on Shanling Q1 but broken on the
FiiO M3K (kernel hang) so leave it disabled for the M3K.

Adds loaders for uImages on the SD card or on a raw flash partition.
These work similarily to load_rockbox() and return a buflib alloc
and size. Booting the image is left up to the caller.

Now that everything has been refactored into separate files the

Drop init_usb(), instead initialize USB early in the main function
so the hardware is placed into a known good state after a USB boot.
The impact on boot time should be minimal.

Perform an unconditional disk_mount_all() from the main function.
