This moves the time conversion function to timefuncs since it has
uses on ports that don't use the FAT driver. This function has no
dependency on the FAT driver as it is so this should not cause any
issues. To reflect this separation the function was renamed to
dostime_mktime since it is really for DOS timestamps. The places
where it was used have also been updated.

This new design saves on binary size and stack usage. The API is
also block- and page-based, requiring awareness of the chip layout
to use properly. Out-of-band areas are also exposed for reading
and writing.
The byte-oriented routines are kept for compatibility with the
existing installer and SPL.

If the commands repeatedly fail it is likely that the AVR is not
programmed. In such case simply continue normal operation. This is
especially important in bootloader as it makes it possible to load new
rockbox build using bootloader USB mode. Otherwise, the only recovery
option would be to use I2C serial.

Use 32-bit monotime AVR counter for time tracking. Set the time by

Do not implement alarm functionality as wakeup is only possible from

This uses an equivalent algorithm but with a different initial value
than we normally use (all bits off vs all bits on). Use the new crc_32r
to replace the original MI4 crc32 implementation.
This frees up some extra space on mi4 targets which gives us more
room on a few very space constrained targets (sansa c200/e200, etc).
Change-Id: Iaaac3ae353b30566156b1404cbf31ca32926203d
This uses the reverse of the polynomial used by the current crc_32
function. The code for this was derived from the implementation used
by tinf. This version is space optimized and should be a good way to
reduce code duplication in other parts of rockbox that use the same
crc32 algorithm. This is mainly of use in areas where DEFLATE is in
use.

Needed for g#3415, and if the comment is to be believed, this needed
updating for recent MIPS targets anyway.
Just blanket enable everything for all targets with >= 8 MiB of RAM.
The only targets with less than this are the Sansa Clip, c200v2, and
m200v4, which all have 2 MB of RAM.
The added code size is around 4 KiB to 7 KiB, depending on the target.

Wait on semaphore until DMA finishes instead of busy waiting. This

Increase peripheral clock frequency, divide AHB by 2 instead of 3.
Function clock frequency is AHB divided by MMC divider + 1.

- Missing mutex unlock in nand_open()
- SET_FEATURE command incorrectly issued as a read operation
- Inverted protection bits, not sure how that happened...
- Block erase skipped ahead by a wrong amount, causing erases
spanning multiple blocks to erase the wrong blocks
This code was buggy as hell... it's in need of a major overhaul.
It's not very flexible or reliable, and access to the flash is
useful during development of a new port, even if not useful once
the port is complete.

On devices that can assign interrupt IN, bulk IN and bulk OUT endpoints
this change results in the serial interface working out of the box on
Linux and Windows. On Linux it is registered as ttyACM device and on
Windows it is assigned a COM port number.
On devices that cannot assign the interrupt IN this change won't have
any effect.
Implement minimum required interface control requests. Respond with
whatever line coding was set to make terminal programs happy.

Disabling double buffering results in expected CPPI TX behaviour. With
the double buffering enabled, sending single ZLP resulted in two ZLPs
being available. The two ZLPs is problematic because this causes Windows
to reset USB device after failed SCSI command.
The problematic sequence on Windows 10 was as follows:
* Host sends SCSI Mode Sense(6) Informational Exceptions Control(0x1C)
* Device sends ZLP
* Device sends command failed response
With endpoint double buffering enabled the ZLP was read twice by host.
As host was expecting command response on the second read (and got ZLP
instead), host attempts recovery by resetting USB device and retrying.

Correctly set endpoint maximum packet size so host will not consider
end of transfer after receiving first packet when transfer is larger
than 64 bytes (at High Speed the endpoint max packet size was set to
64 but according to descriptor it is 512).
Split DMA transfers up to CPPI_MAX_FRAG so we get single interrupt
after each call to tnetv_cppi_send().

Avoids having to #define the names of GPIO pin interrupt handlers,

The GPIO API was pretty clunky and pin settings were decentralized,
making it hard to see what was happening and making GPIO stuff look
like a mess, frankly.
Instead of passing clunky (port, pin) pairs everywhere, GPIOs are now
identified with a single int. The extra overhead should be minimal as
GPIO configuration is generally not on a performance-critical path.
Pin assignments are now mostly consolidated in gpio-target.h and put
in various tables so gpio_init() can assign most pins at boot time.
Most drivers no longer need to touch GPIOs and basic pin I/O stuff
can happen without config since pins are put into the right state.
IRQ pins still need to be configured manually before use.

The old name was a bit misleading. AXP173 is sort of the lowest common
denominator of a series of related chips. The M3K uses an AXP192 which
has a few extra features vs. the AXP173.
New voltage regulator stuff was added for the sake of the Shanling Q1
native port (that player also uses an AXP192).

Clearing recoverzap parameter exists the Recovery Mode. This makes it

Enable write-through cache on flash memory as write-back complicates

Motivation: turns out the DMA in the M3K's MSC controller is buggy,
and can't handle unaligned addresses properly despite the HW docs
claiming otherwise.
Extending the FAT driver bounce buffering code is the easiest way
to work around the problem (but probably not the most efficient).
