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
allows the CPU to be used by other tasks during transfers.
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.

The old code would seek forward by the frame length, expecting to see a
frame header there, perform a validity check, and then seek back to the
current header.
Unfortunately this doesn't handle situations where there is extra padding
between the frames, leading us to potentially read garbage, causing the
validity tests to fail and rejecting the file outright.
Instead, keep track of the previous valid header/position, and if we find
"valid" headers in a row return the first after seeking back to it.
This change allows the file referenced in FS13299 to be properly parsed, but
further work is needed to get the file to be playable. (file reports itself
as layer 1, variable bit rate, variable sample rate!)

Intercept buttonpress and action, and nullify both if the button

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.

This imports the MD5 code used by other utilities and creates
a function for checking the provided NK.bin against known original
firmware checksums. Integration into mknkboot and beastpatcher is
also added.
For the sake of consistency with beastpatcher, mknkboot had its
printf statements rewrote to print to stderr like beastpatcher
does.

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().

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).
