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

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

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.
Change-Id: I373f465dbbdafe94738f619748cbb0278fc2c25f
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.

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.

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.
Change-Id: Ib2d17bcea53bdea1c4c5496cec0c4eee5dd66069
This problem actually had nothing to do with USB boot; it's
because the cable is plugged in when the USB mode menu item
is selected. The USB thread detected the select button press
and went into charge-only mode (as it usually does when you
hold down a key in Rockbox). This is fixed by having the USB
thread ignore most keys in the bootloader.
USB connect events are delivered via the button queue, and
there were also cases where the connection could be missed
if the event happened within another UI screen. This should
also be fixed.

there is a 1MB free region that is used to load the firmware but we
shouldn't need that till after a USB connection
so here is my 2nd try
Change-Id: I2552db3a7fba019d7e7188984432f758ddafe548
* Power button is what forces entry into USB mode
(can't use the other buttons due to the long SADC warmup)
* Inching closer to working USB disk mode (starts then disconnects!
Change-Id: I45ff1c61f39e0e0c3615b38278f5c91b6ef2ed6c
* Rework the LCD initialization a bit
* Power off after 5 seconds if we hit a fatal error
* Turn on verbose output if PLAY is held down on powerup
* Minor code style cleanups
The goal is to not perform the LCD init unless it's needed; ie
only if we run into an error or enter USB mode.
Change-Id: I3f93e881ff55d104f453985ed452f35b433a7d99
* Explicitly clear the caches prior to launching the binary
* Ensure the function that launches the binary is in iram
* Re-sequenced some of the subsystem initializations
* Fixes for USB mode

What works:
- LCD: 16-bit RGB565
- all buttons, including scrollwheel
- SD Card
- Battery level and charging/not charging status
- USB
- audio
- sample rate switching
- HP / LO detect, with "safe" fixed LO volume -
LO volume will only be put to user-defined max volume
if headphones are not present.
- rtc
- Plugins build, tried a couple and they seem OK
- Bootloader, installable to nand via usbboot
What doesn't work:
- Dual Boot
- power on/off has intermittent, low volume audio click
(sometimes it's completely silent, sometimes there's
a click)
- Audio uses 16-bit volume scaling, so clicking/popping
is pretty bad at lower volumes - need 32 bit volume
scaling, 24 bit I2S data
- USB HID keys not yet defined
- no jztool support
Unknowns:
- Stereo Switch pins: Direction select, AC_DC
(probably not even hooked up)
- What is the actual purpose of the Stereo Swtich?
- How does the bluetooth module connect?
"Someday" stuff:
- get LCD working at higher bit depth
- Bluetooth

- Audio playback works
- Touchscreen and buttons work
- Bootloader works and is capable of dual boot
- Plugins are working
- Cabbiev2 theme has been ported
- Stable for general usage
Thanks to Marc Aarts for porting Cabbiev2 and plugin bitmaps.
There's a few minor known issues:
- Bootloader must be installed manually using 'usbboot' as there is
no support in jztool yet.
- Keymaps may be lacking, need further testing and feedback.
- Some plugins may not be fully adapted to the screen size and could
benefit from further tweaking.
- LCD shows abnormal effects under some circumstances: for example,
after viewing a mostly black screen an afterimage appears briefly
when going back to a brightly-lit screen. Sudden power-off without
proper shutdown of the backlight causes a "dissolving" effect.
- CW2015 battery reporting driver is buggy, and disabled for now.
Battery reporting is currently voltage-based using the AXP192.
