soc_core: additional csr_alignment follow-up fixes
 2019-07-08 19:03:28 +02:00
Gabriel L. Somlo e42f33ede1 soc_core: additional csr_alignment follow-up fixes 
- Update a few additional places to use DFII_ADDR_SHIFT instead of
  a hard-coded 4, which assumed 32-bit alignment.

- Force 64-bit alignment Rocket -- the only supported configuration!

This is a fixup for commit f4770219, tested on Rocket and 64bit Linux.

Florent Kermarrec 740629ba53 soc_core: remove 256MB mem_map limitation 
mem_map was limited to 8 256MB for simplicity but has become an issue for
complex SoCs. Default mem_map size is still 256MB (retro-compatibility) but
size can now be specified.

Florent Kermarrec ecf999b8c7 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
 2019-06-21 10:26:07 +02:00
William D. Jones 7656f54d0a 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.

 2019-06-19 08:32:38 +02:00
Gabriel L. Somlo ab827d210d 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.
