Florent Kermarrec 3d32ac3d2e software: Avoid libase renaming to libutils/libcomm and keep readchar/putsnonl retro-compatibility. 
We'll maybe do it but that's probably not the right time. We have to make
the picolibc switch as smooth as possible for users (and so avoid update
as much as possible).

In the long term, it would be good to provide a LiteX C SDK, so we'll make
eventual changes when doing this.

Florent Kermarrec 944732aa19 soc/add_sdram: Also remove ResetInserter on axi.AXI2Wishbone. 2021-09-27 15:46:19 +02:00
Florent Kermarrec ce0551b44a cpu/rocket/core: Remove ResetInserter on adapters. 
Previously, the SoCController was only reseting the CPU, which required adding
these ResetInserters. Now that the SoCController resets both CPU and peripherals
these ResetInserters are redundant and no longer useful.

Gabriel Somlo 07e47d9357 cpu/rocket: add quad-core (smp) variants 
- 4-core "full" (fpu-enabled) variants with double, quad mem. bus width
- 4-core "linux" (fpu-less) variant with single (64-bit) mem. bus width
 2021-09-22 16:59:04 -04:00
Gabriel Somlo 901b19828c cpu/rocket: include core count as per-variant parameter 
Repurpose (and rename to `CPU_SIZE_PARAMS`) the current
`AXI_DATA_WIDTHS` array. In addition to axi widths for
mem and mmio ports, also include each variant's number
of cores, to facilitate dynamically generated per-core
signals.

Also, no need for non-boot cores to `call smp_slave`, it's the
immediately following instruction for them already.
