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.

Merge pull request #976 from antmicro/libbase-replacement 
Replace libbase with picolibc

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.

Rocket SMP support
 2021-09-23 10:56:06 +02:00
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

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.

Merge pull request #1041 from gsomlo/gls-vex-smp-fix 
cpu/vexriscv_smp/crt0.S: only boot core should run data_init

Florent Kermarrec 60c6077c32 remote/comm_udp: Add padding bytes to Etherbone probe. 
Now required with LiteEth dropping exceeding payload.
 2021-09-22 16:52:08 +02:00
Gabriel Somlo 23b2ac2013 cpu/vexriscv_smp/crt0.S: only boot core should run data_init 
Also, no need for non-boot cores to `call smp_slave`, it's the
immediately following instruction for them already.

Michal Sieron 3d4a64e112 Update stdio code in libc 
Picolibc now requires to create stdin, stdout and stderr files
ourselves instead of __iob array. Thus changes and renaming
of iob.c to stdio.c

f320a0aa17
added option to select default printf format, so using
picolibc.specs or defining PRINTF_LEVEL is no longer needed.

Michal Sieron ef7b287248 Disable thread local storage (TLS) in picolibc 
It was causing some compilation issues with lm32.
As global errno was enabled anyway, it was easier 
to disable TLS whatsoever.

Michal Sieron c84105f399 Disable LTO for picolibc and use picolibc.specs 
Use picolibc.specs to specify integer only printf/scanf.

To do that, we need to pass specs file with options to
the linker. With LTO enabled, name mapping was failing,
so LTO is now disabled for picolibc compilation only.

This also means, that exchange.c and arc4random.c no
longer need to be recompiled and added back.
