Christian Klarhorst ebe22ca2b6 cores/vexriscv_smp: Fix vexriscv_smp doesn't build without a memory bus 
The current code only works with a memory bus because otherwise
"generate_cluster_name" doesn't get called.
Cluster_name is only needed in the finalize phase.
Therefore, the name will now be generated just before its usage.

Verifiable with: 
litex_sim --cpu-type vexriscv_smp (should be broken before this commit)

build/lattice: work around lack of SDR I/O primitives in nextpnr

Michal Sieron 8c2e13bff7 Fix stack alignment 
RISC-V requires stack to be aligned to 16 bytes.
1d5384e669/riscv-elf.md?plain=1#L183

Right now, in bios/linker.ld, `_fstack` is being set to 8 bytes
before the end of sram region.
```
PROVIDE(_fstack = ORIGIN(sram) + LENGTH(sram) - 8);
```

Removing ` - 8` makes it aligned to 16.

Also there are changes in crt0.S for vexriscv,
vexriscv_smp and cv32e40p.

Code that was setting up stack, was adding 4 to its address
for some reason.

Removing it makes it aligned to 8 bytes, and with change in
bios/linker.ld to 16 bytes.

It also fixes `printf` with long long integers on 32bit
CPUs ([relevant issue](https://github.com/riscv/riscv-gcc/issues/63)).

Florent Kermarrec ce5864983d soc/add_cpu: Add memory mapping overrides to build log and make an exception for the CPUNone case. 
A regular CPU can provides specific mapping constraints and we are overriding provided mapping
with these constraints.

The case of CPUNone is different and we can do the opposite: Give priority to User's mapping.

For the regular CPU case, the override was done silently, it is now logged during the build.

Florent Kermarrec 60c4a1b667 liblitespi/spiflash: Review #979 and other cleanups. 
- Rename optional #define and allow defining them externally.
- Add comments.
- Rename FLASH_CHIP_MX25L12833F_QUAD to SPIFLASH_MODULE_QUAD_CAPABLE.
- Rename FLASH_CHIP_MX25L12833F_QPI  to SPIFLASH_MODULE_QPI_CAPABLE.

The instructions used for QUAD/QPI are probably different between chips, we could
imagine providing them through the LiteX integration based on the passed SPI Flash
module.

Florent Kermarrec 505c8b85d6 soc/add_spi_flash: Reduce LiteSPIPHY default divisor to max(2, self.sys_clk_freq/clk_freq). 
One small FPGAs running the BIOS from SPI Flash, the default divisor of 9 was slowing down too
much BIOS boot time (It was OK on reboot after liblitespi auto-calibration). Reduce the default
divisor to avoid this.

Florent Kermarrec 1ce48a973b clock/lattice_ecp5: Fix and rework 4-output solver implementation. 
The implementation was causing regressions on actual designs, rework done:
- Only keep a common iteration loop as before.
- Add iteration on CLKO dividers (to fall in the VCO range).
- Do the iterations as before, if while doing it we find a clock suitable for feedback: just use it.
- If no feedback clock has been found: create it (if at least one free output available, if not raise an error).
