This supply is shared by the USB PHY and the audio codec,
so it needs to be reference counted to allow them to be
powered up & down independently (and not just leave the
1V8 regulator enabled all the time).

This allows targets to select full speed operation instead
of the default high-speed mode, which is mainly interesting
for debugging USB communication.

If the PHY doesn't correctly report the ID pin state,
then the DWC2 core may operate in host mode by default.
Defining USB_DW_FORCE_DEVICE_MODE in the target config
will set the FDMOD bit in the GUSBCFG register to force
the core into device mode regardless of what the PHY
reports.

Two cache discards for targets with POST_DMA_FLUSH were
not properly guarded by USB_DW_ARCH_SLAVE, which causes
data loss when DMA is disabled.

Buffer contents are only moved after the callback
returns, so we need to log the path before it has
been updated to prevent reading garbage.

The ARM assembly versions of memcpy and memmove try to
directly modify the PC based on the number of bytes to
be copied as an "optimization"; but this only works if
instructions are guaranteed to be 4 bytes wide.
This trick is completely broken on Cortex-M, since an
instruction can be 2-4 bytes wide: for example a memcpy
of 4 bytes ends up storing 32 bytes worth of garbage to
the target address!
Use the C memcpy/memmove implementations for Cortex-M
instead; fixing the ASM version is more trouble than
it's worth.

asm.make replaces source files listed in asm/SOURCES with
a corresponding .c or .S file under firmware/asm/${ARCH}.
This makes it difficult to handle differences within one
architecture, eg. different instruction sets or versions
of the architecture.
Get rid of asm.make, and instead use the preprocessor to
select the architecture-specific sources directly from
asm/SOURCES. This is slightly more verbose but is more
flexible.

Define HAVE_LC_OPEN_FROM_MEM if the target implements
lc_open_from_mem(). Make HAVE_CODEC_BUFFERING depend
on this feature.

Move HAVE_CODEC_BUFFERING to config.h, and disable all
related code on targets that don't support the feature,
ie. hosted targets that can't implement lc_open_from_mem().

Add CONFIG_BINFMT to select the binary format used for
plugins/codecs and define two options for the existing
implementations (native ".rock" format or dlopen-based).
Split the load_code.h header into two separate headers
to make it look less messy.

Enable pullups on SDMMC CMD/DATx lines and set output
speed to medium. Using HIGH and VERYHIGH speeds seems
to cause data corruption, with frequent CRC failures.

sdmmc_host is a portable driver for targets with SD/MMC
storage. It handles all the logic needed to initialize
and access SD/MMC devices which is common to all targets.
Targets only need to implement functions to issue SD/MMC
commands, manage clocks & power, and managing the insert
state of the card (if it is hotswappable). This vastly
reduces the work needed to get a new SD/MMC based target
up & running.
At present it's only written for and tested with SD cards,
as I don't have access to an MMC-based target to test on.

- existing class drivers are placed to config 1
- drivers_connected==true is replaced with usb_config!=0
- supports config transition between nonzero configs
- STALL if request set_config was invalid

this commit has following changes:
- introduce `usb_drv_ep_spec` table to udc drivers, which represents
endpoint characteristics.
- introduce 'ep_allocs' table to class drivers, which represents what
endpoint type does the class driver want.
- implement endpoint matching logic to usb core.
this is a required step to implement usb config switching, because we
need to create config descriptors without actually initializing endpoints.

Use the optimized version based on __buitlin_ctz() which GCC
will compile to two instructions (rbit, ctz) on Cortex-M4/M7;
faster and smaller than the handcoded assembly version.

Given the myriad of clocking options the STM32H7 family
provides, it is easiest to let targets simply implement
what they need.

Supporting large transfers (>64k) isn't really needed;

Add an optional sequence in the startup code to disable clock
gating when the CPU goes to sleep. Normally the D1 and D3 domain
clocks can be automatically gated when the CPU is asleep, and
because the debug infrastructure is clocked from these domains,
the debugger cannot attach when those clocks are stopped.
Setting some bits in DBGMCU_CR prevents this problem, but will
increase power consumption, hence it isn't enabled by default.

The ZEN V target is the only one which has volume buttons,
but lacks the menu and shortcut buttons.
IMO an independant keymap will make maintenance easier.

The layout of 'struct regs' is a bit different on Cortex-M
