595aa806e6 efm32: add USB mass storage class code
We added this in the main branch earlier, but efm32 usb code was in
flux.  Added now that it's stable again.

bc70d3b459 add USB mass storage class code where it was ommitted
Quite a few families didn't get the usb mass storage class code added.
Add it to all devices with usb support.

2204f447bb BREAKING: stm32f3:rcc: add more generic pll setup routines
Deprecate the old routine and make a new one that actually handles HSI
and HSE properly, and includes the predivider and the usb divider
settings as well.

f0e128673d Add DMA support to STM32L0
STM32L0 uses the same DMA peripheral as STM32F0, F1, L1 and others
with some differences. Those are mostly in the number of supported
controllers and channels.

This patch enables the basic support with no attempt to only expose
the available controllers / channels.

For more information see the ST Application Note AN2548.

255a594300 stm32: spi-v2: enable SSOE by default for the common case
See also f80bff2133

This makes the v2 peripheral behave consistently with the v1 peripheral
code, and more in line with users expectations.

bf125e91f9 stm32: rework spi, based on PR #740 and #742.
split spi stuff in three part:
 - v1 : basic spi peripheral
 - v1_frf : v1 spi with frf mode additional bit in spi_cr2 / spi_sr
 - v2 : spi with variable datasize, fifo and other fancy stuff.

v1 maps to f1 chips
v1_frf to f2, f4 and l0,l1
v2 to f0, f3 and l4

This breaks spi_master_init API for v2 devices : function prototype from
common spi header used to be abused, with DFF bit reused for CRCL bit.
New v2 spi_master_init does not handle anymore CRCL bits, as it does not
usually mess with other crc configuration.

0deb58c73c stm32: fix spi_init_master documentation.
Doc mentions SPI_CR_BR_FPCLK_*, but spi_init_master needs offseted register value (SPI_CR_BAUDRATE_FPCLK_*).
Align documentation with code.

9a05dcb6c0 ld scripts: drop duplication of standard sections
Instead of every "simple" target having their own duplicate file with
all the section mappings, just provide a single, simple,
"cortex-m-generic.ld" that works with our startup code and any simple
rom/ram system.  This also drops the pointless copying of files all over
the place.  Using -L flags properly is sufficient, and the standard file
is now in the root of the library already.

5160d7996c efm32: Split efm32/lg into /lg and /common.
Somewhat replaces some earlier work done by hg/lg, but much more
complete, so we kept it as is, because it's bringing in even more parts
after this.

2b1ddc8490 sam/4l: monster commit
The original submitter of this squished everything into one series, and
has not returned. The code mostly appears good, and review comments were
followed for the most part.  The project doesn't really maintain any
testing or board farm for sam3/sam4 parts, so we're going to just trust
our users.

fixed some typos from the manual and poor merging/rebaseing,

The ADC v2 peripheral doesn't have the same behaviour of starting, where
the hardware clears the bit immediately, on v2, it is not cleared until
the ADC is stopped, or the end of sequence flag is set.
