soc/cores: add usb_fifo with FT245 USB FIFO PHY from LiteUSB, deprecate LiteUSB
...
LiteUSB was not up to date was not a real USB PHY but was just providing USB FIFO PHYs.
New true USB cores are now available: Daisho, ValentyUSB, so it's better using
then for true USB support. We only keep the FT245 FIFO PHY in LiteX that can be
useful to interface with USB2/USB3 USB FIFOs.

soc: cores: add up5kspram module
...
The ICE40UP5K has 128 kB of SPRAM that's designed to be used
as memory for a softcore. This memory is actually 4 16-bit
chunks that we can gang together to give us either 64 kB or
128 kB.
Add a module that will allow us to use this memory in an ICE40.

tools/litex_sim: fix default endianness for mem_init
...
Initializing ROM and/or RAM content requires knowing the CPU
endianness before the SimSoC->SoCSDRAM->SoCCore constructor
sequence is invoked (before the SoC's self.cpu.endianness
could be accessed). Given that the majority of supported CPU
models use "little", set it as the new default, and override
only for the two models that use "big" endianness.

bios: Fix build when ethphy is present but ethmac is not.
...
While testing my Ethernet DMA, I renamed the `ethmac` module to `ethmac_dma` so that it wouldn't be used from the BIOS, but I got an undefined reference to `eth_init` because `bios.c` checks different CSR defines than the code that defines `eth_init`.

In most of the case, execution speed is already fast enough with -O0 and
with complex design -O0 is a lost faster to compile than -O3. In the future
we could add a switch to choose which optimization we want.
