Add 'volatile' qualifier to new CSR accessors
2020-02-21 21:08:22 +01:00
Gabriel Somlo 173117ad4b Add 'volatile' qualifier to new CSR accessors
Through their use of the MMPTR() macro, the "classic"
csr_[read|write]simple() accsessors identify the MMIO
subregister with the 'volatile' qualifier.

Adjust the new, csr_[rd|wr]_uint[8|16|32|64]() accessors
to also utilize the 'volatile' qualifier. Since accesses
are implicit (a[i], where a is an 'unsigned long *'),
change 'a' to be a 'volatile unsigned long *' instead.

No difference was noticed in opcodes generated using the
gcc9 risc-v cross-compiler on x86_64 with standard LiteX
cflags (vexriscv and rocket were tested), but since
reports exist that 'volatile' matters on some combinations
of compilers and targets, add the 'volatile' qualifier just
to be on the safe side.

Sean Cross a2f1683b97 doc: rename lxsocdoc -> socdoc and update readme
With the merge of lxsocdoc into upstream litex, the old name of
"lxsocdoc" doesn't make as much sense.  Additionally, the import paths
are now different.

Rename this file to reflect the new home of `soc/doc`, and update the
code examples to work with the new name.

Sean Cross baa29f1b03 doc: fix regression with new irq manager
Previously, we were accessing the `soc.soc_interrupt_map` property in
order to be able to enumerate the interrupts.  This has been subsumed
into a more general `irq` object that manages the interrupts.

Use `soc.irq.locs` instead of `soc.soc_interrupt_map` as the authority
on interrupts for both doc and export.

This fixes #385.
