William D. Jones ce243820fe tools/litex_term: Convert some common scan codes into ANSI codes on Windows. 2021-01-11 21:02:37 -05:00
William D. Jones 5babcadbed tools/litex_term: Set ENABLE_VIRTUAL_TERMINAL_PROCESSING flag on Windows. 2021-01-11 19:54:21 -05:00
William D. Jones bfc624f23e tools/litex_term: Avoid importing termios and pty on Windows. 2021-01-11 14:51:55 -05:00
Florent Kermarrec 460fada3ac tools/litex_term: revert LiteXTerm to threading (multiprocessing breaks Windows/OS-X). 
Ideally we should switch to AsyncIO as some point.

Florent Kermarrec 1ce194007b software: allow BIOS compilation with UART disabled. 2021-01-08 19:18:44 +01:00
Florent Kermarrec 19fda3364a tools/litex_term: fix 100% cpu load after refactoring (thanks sergpolkin). 2021-01-08 13:57:33 +01:00
Florent Kermarrec 5f9c4a4ab4 soc/cores/gpio: remove intermediate _pads signal. 2021-01-06 21:39:02 +01:00
Florent Kermarrec 0984308318 cores/gpio: add assertion on pads (has to be a Signal). 
Due to the bi-directional nature of tristate, Cat is not supported (so also
not platform.request_all).

Florent Kermarrec f31f9a20f0 boards: remove and switch to litex_boards. 
Keeping board definition files directly in LiteX is no longer useful since we are already relying on board
definitions files from LiteX-Boards (https://github.com/litex-hub/litex-boards) in various benches/projects
and having definitions files directly in LiteX creates confusion/additional work.

For projects using board definition files from LiteX, the litex.boards import can just be replaced with litex_boards:

from litex.boards.platforms import kc705

from litex_boards.platforms import kc705

Florent Kermarrec d9a44ce10f tools/litex_json2dts: minor changes/cleanup on #745. 
- shorten args description.
- avoid mixing initrd_start/initrd_start_offset: just use initrd_start and indicate it's relative.
- others minor cleanups.

Stafford Horne a2c9b17959 dts: Allow specifying initrd position and size via args 
This is needed as my initrd size is much larger than the default 8mb.
Also, sometimes the kernel I build is also large, so its good to be
able to move the initrd starting position.

Florent Kermarrec 1a338b602a software/bios: add new mem_list command to list available memory regions. 
This is useful to know the memory regions available and use the mem_xy commands
on them:

List the memory regions:

litex> mem_list
Available memory regions:
ROM       0x00000000 0x8000
SRAM      0x01000000 0x2000
MAIN_RAM  0x40000000 0x10000000
CSR       0x82000000 0x10000

Test 0x1000 bytes of MAIN_RAM:

litex> mem_test 0x40000000 0x1000
Memtest at 0x40000000 (4KiB)...
  Write: 0x40000000-0x40001000 4KiB
   Read: 0x40000000-0x40001000 4KiB
Memtest OK

Test speed on 0x1000 bytes of MAIN_RAM:

 2020-12-22 09:40:53 -08:00
Stafford Horne 3067c57080 mor1kx: Enable gcc compiler flag for cmov

 2020-12-22 22:10:42 +09:00
Stafford Horne 51327e00b5 mor1kx: Enable rotate, sign extend under linux, new fpu extension 
My thought is that if we are running linux the FPGA should be able to
handle these extra instruction's footprint.  Also, since we are running
on linux there may be any kind of software running on the CPU, so allow
handling these instructions.

FPU is added bia a new +fpu extension.

But really, I am running GLIBC tests and they run faster with this
enabled.

Florent Kermarrec d90d3e043b software/liblitedram: add optional SDRAM_TEST_DISABLE that can be defined to full disable SDRAM test.
