spi_flash: correct documentation on SPI mode
...
The SPI mode is actually mode3, since the output value is updated on the
falling edge of CLK and the input value is updated on the rising edge.
This also clarifies some of the documentation based on experience with
the core.

soc/cores/clock: add lock reg and assign reset
...
It was necessary to add drp_locked CSR for reading LOCK signal from
MMCM. Additionally, input signal RESET from MMCM was not driven by
any signal to do a proper reset of MMCM module thus it was impossible
to perform entirely correct dynamic clock reconfiguration.

soc_sdram, bios/sdram: support sdram init for csr_data_width <= 32
...
Enable SDRAM to be initialized when csr_data_width > 8 bits.
Currently, csr_data_width up to 32 bits is supported.
Read leveling tested with csr_data_width [8, 16, 32] on the
ecp5-versa5g and trellisboard (using yosys/trellis/nextpnr),
and on the nexys4ddr (using Vivado).

...
With high speed link (10gbps XGMII ethernet for example), stream data_width is generally
> 8-bit which make header/data un-aligned on bytes boundaries. The change allows the
Packetizer/Depacketizer to work on stream with a data_width > 8-bit.
