bunnie 33d9e45a8b fix formatting on spiopi 
Pycharm really butchered the code when I did a copy-and-paste...
it has questionable default formatting preferences.

Mariusz Glebocki 90fe585003 build/sim: allow to use environment's {C,LD}FLAGS 
There are use cases where additional flags should be added to CFLAGS or
LDFLAGS, e.g. when using Conda environment.

Sean Cross 58598d4fda integration: svd: move svd generation to `export` 
It was suggested that we should move svd generation into `export`,
alongside the rest of the generators such as csv, json, and h.  This
performs this move, while keeping a compatible `generate_svd()` function
inside `soc/doc/`.

Sean Cross 73ed7e564c soc: doc: use sphinx toctree as it was intended 
The sphinx toctree was behaving oddly, and so previously we were
ignoring it completely.  This patch causes it to be used correctly,
which removes the need for double-including various sections.

Sean Cross 7c3bc0b09f litex-doc: initial merge of lxsocdoc 
lxsocdoc enables automatic documentation of litex projects, including
automatic generation of SVD files.

This merges the existing lxsocdoc distribution into the `soc/doc` directory.

software, integration/export: (re-)expose CSR subregister accessors
 2020-01-30 08:18:12 +01:00
Gabriel Somlo ff2775c264 software, integration/export: (re-)expose CSR subregister accessors 
Expose a pair of `csr_[read|write]_simple()` subregister accessors, and
restore the way dedicated accessors are generated in "generated/csr.h"
to use hard-coded combinations of shifts and subregister accessor calls.

This restores downstream ability to override CSR handling at the
subregister accessor level.
