This code was copied from the f4, and blindly modified to make it seem
to work. The f3 has separate flags for EOC and EOS, it doesn't use a
second bit to configure what the EOC bit does.
Consequently, update the documentation to correctly indicate that the
EOC bits are only set per conversion.

When operating on registers in code that is common for both usb cores,
make sure to use the REBASE macros to operate on the correct peripheral.

The three existing usb drivers have no possible path that doesn't return
the object here, so I've left that comment, but it is plausible that
future drivers might have some reason that allows failing to init. We
should strive to avoid that though.
Fixes github issue: #494
The common case for SPI ports in master mode is that they are not
also running as Slaves some times. For these chips the SSOE bit must
be set (or NSS tied high). Since it is common for people to use a separate
GPIO to select remote slaves and they expect the master to always be the master
this sets that up by default.
-ggdb3 make slightly bigger .elf files, but allows gdb to understand
macros, which libopenocm3 uses somewhat extensively. Make this the
default, and pull it up to the common base makefile, so it can be easily
substituted.
While there might be other places that are missing this include, this
particular file is clearly missing them, and has resulted in a few separate bug
reports. Fix it right now, in the name of continuous improvement.
Fixes#310 and #427
This adds MCO source selection to some targets, and removes and standardizes
the mask/shift usage for all targets. For devices that support MCO2, this
supports only MCO1. No attempt has been made to extract MCO prescaler, which
is not available on all F1 and F3.
F0 should check the oscillator ready bits in the regular registers, just
like the docs claim, and just like every other stm32, rather than trying
to check for the interrupt flags.

This commit implements the support for one interface to have multiple
altsettings. It also adds hook that user can use to perform actions
when the alsetting switch is performed by host.
Changes:
* For backward compatibility, placed a pointer instead of allocating memory for whole interface struct.
* Always execute callback (even if the current interface alternate-settings matches).
* Multiple configuration support.

These devices have 32kiB RAM and 256kiB flash and are otherwise
register compatible with the f373x8 and f373xc devices.

When writing the USB endpoint register, USB_EP_RX_CTR (bit 15) and
USB_EP_TX_CTR (bit 7) should be set to avoid inadvertently clearing
either bit.
Prior to this patch end points could indefinately stall if the hardware
changed these bits between the time they are read and when they were
written.
