Gabriel Somlo b2103f4ad8 bios/sdcard: provide sdclk_set_clk() stub for clocker-less targets
Targets which lack an adjustable clocker will not expose the required
registers. Provide a stub sdclk_set_clk() routine for those situations.

Merge pull request #425 from esden/csr-cod-split-reg
Make CSR documentation diagrams, with more than 8 bits, be split into multiple lanes.
2020-03-14 18:08:24 +08:00
Piotr Esden-Tempski 57576fa8fc Add bit more logic to decide when to switch to multilane CSR documentation.
Now we only generate multilane bitfield documentation when the CSR has
fields, and the smallest field is less than 8bit long. As this is when
we start running into space problems with the field names.

Piotr Esden-Tempski dda7a8c5f3 Split CSR documentation diagrams with more than 8 bits into multiple lanes.
In cases when each CSR bit has a name and we use CSR with more than 8
bits, the register diagram quickly becomes crowded and hard to read.

With this patch we split the register into multiple lanes of 8 bits
each.

Florent Kermarrec aec1bfbeb4 cores/clock: simplify Fractional Divide support on S7MMCM.
Specific clkoutn_divide_range can now be provided by specialized XilinxClocking classes.
When provided, the specific range will be used. Floats are also now supported in the
range definition/iteration.

Florent Kermarrec 979f98ea31 software: revert LTO changes (Disable it).
It seems LTO is not yet fully working with all configurations, so it's better
reverting the changes for now.
- cause issues with LM32 available compilers.
- seems to cause issues with min/lite variant of VexRiscv.
- seems to cause issues with some litex-buildenv configurations. (see https://github.com/enjoy-digital/litex/issues/417).

Florent Kermarrec 3c0b97eec8 cores/clock/USIDELAYCTRL: use separate reset/ready counters and set cd_sys.rst internally.
This is the behaviour that was duplicated in each target. Integrating it here
will allow simplifying the targets.

Sean Cross a2f61b4e80 soc/cores/spi_opi: documentation fixes
The ModuleDoc-generated documentation for the spi_opi module produced
slightly invalid output due to ambiguities in how rst assigns headers.
As a result, sections from the spi_opi document would appear as full
sections.

This cleans up these errors so that it parses properly under sphinx.

bunnie 5b92bf2d57 add fractional division options to clk0 config on PLL
S7 MMCMs allow fractional divider on clock 0. Add a fallback
to try fractional values on clock 0 if a solution can't be found.

This is necessary for e.g. generating both a 100MHz and 48MHz
clock from a 12MHz source with margin=0
