Florent Kermarrec 41eb21b343 soc_core: optimize mem_decoder
Non-optimized version was tested on 7-series and was additional resource usage
was not noticeable. This does not seems to be the case on iCE40 (see #220), so
hand optimize it. On 256MB aligned addresses, it should be equivalent to the
old decoder used by previously in LiteX.

The only requirement is that to have address aligned on size, which was already
the case. An assertion will trigger it this condition is not respected.

Mateusz Holenko 8335f13fb1 bios/boot: rework netboot/flashboot for VexRiscv in linux variant
Get rid of NETBOOT_LINUX_VEXRISCV/FLASHBOOT_LINUX_VEXRISCV defines
and use information about CPU_TYPE and CPU_VARIANT instead.

Use common kernel/rootfs/device tree/emulator images layout
when booting over network and from flash.

Mateusz Holenko a19bdd0e6a soc_core: generate extra string-based config defines
C preprocessor does not allow to compare strings, so
the current defines are not usable at the compile time.
This adds new defines that can be ifdefed.

Florent Kermarrec 769d15d433 cores/spi: move CSR control/status to add_control method, add loopback capability and simple xfer loopback test
Moving control/status registers to add_control method allow using SPIMaster directly with exposed signals.
Add loopback capability (mostly for simulation, but can be useful on hardware too).

Florent Kermarrec b0192e5f8b soc_core: use fixed 16MB CSR address space
Using too small CSR address space cause a regression on PCIe SoC, this would
need to be understood if we want to reduce CSR address space under 16MB.
