3a4da9381e change an underdocumented definition that turns
out to be important, yet not documented in the linux uapi definitions.
Revert that change, and document the magic values so this doesn't happen again.

Bootloaders don't have support for queue_peek or other advanced
queue functionality, so USB-enabled bootloaders can't play these games.

mmc_sleepnow() was accidentally removed from the imx233 sdmmc code,
causing the sansa fuze+ build to fail.

Note that USB current limiting is more or less wishful
thinking; only the charge current is limited, but the
system could easily draw more than 100 mA by itself.

storage_sleepnow() is the one that is actually implemented
by storage drivers. storage_sleep() sends a Q_STORAGE_SLEEP
event to the storage thread, which will normally end up
calling the driver's sleepnow() function.

For commit-type operations it's useful to be able to pass
unaligned addresses, so round the address/size to ensure
all cache lines in the address range are hit.

Enable high speed USB for the Echo R1. Includes reasonably
complete support for full speed USB on the STM32H743 since
that was necessary to debug why it wasn't working at first
(which turned out to be a bug in memcpy, not a hardware or
driver issue).

The "mov lr, pc" instruction doesn't link a proper return
address in Thumb mode: bit 0 will be unset, leading to a
UsageFault exception when returning from the thread's main
function.
Cortex-M has the "blx" instruction to automatically branch
and link the correct return address, so use that.

The implementations diverge enough that it is too confusing
to support them in the same source file; split them so it
is easier to understand.

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.

This commit does the following changes:
- Fix mkdir implementation not reporting EEXIST error.
- Fix database build feature.
- Small speed-up when parsing directories and files.
- Fix buffering thread hogging cpu and preventing other threads to run.
- Fix sdl plugins not compiling by re-adding ctru specific cflags in sdl.make.

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.

All non-simulator and non-hostfs targets are required to implement storage_get_info() since 04dc052a

Define HAVE_LC_OPEN_FROM_MEM if the target implements
lc_open_from_mem(). Make HAVE_CODEC_BUFFERING depend
on this feature.
Change-Id: If5f70db58963dcdc33848b860c028841ac380ab2
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.
