cc6877df9e fhdl: allow use of ResetSignal() on resetless clock domains 2015-07-27 01:51:52 +08:00

50cf70140b Update libbase/linker-sdram.ld with -fPIC support. 2015-07-26 16:15:02 +03:00
whitequark
c8ffd0c9ee Switch to -fPIC. 
Using -fPIC for everything allows to link the MiSoC static libraries
both into static images such as the BIOS as well as
into shared libraries.

a8cd3b9adc Remove useless includes pulled in by libunwind. 
These aren't used by libunwind in any configuration and
should be also removed in upstream.
 2015-07-26 13:12:23 +03:00
whitequark
f6639c1833 Add libunwind. 2015-07-26 12:59:18 +03:00
whitequark
24463a168a Add a stub getenv() implementation. 
This is not strictly necessary to build libunwind (it can
be built with -DNDEBUG), but it will be handy while it is
debugged.

It can be removed afterwards.
 2015-07-26 12:55:52 +03:00
whitequark
b2710e437c Add a stub pthread header. 
The header implements only the pthread rwlock interface, which
never actually locks.

This is necessary to build libunwind.
 2015-07-26 12:54:40 +03:00
whitequark
b5048f6cf1 Add headers for the dynamic linker interface. 
These are required for libunwind to discover
the exception frame headers.
 2015-07-26 12:53:18 +03:00
whitequark
7a9975ab5a Add a stub C++ standard library. 
This is necessary to build libunwind.
 2015-07-26 12:49:21 +03:00
whitequark
5502cec3da Add basic inttypes.h. 
This is taken from glibc. Only PRI* definitions are imported;
functions are not.
 2015-07-26 12:44:13 +03:00

eef1aa77ef Mark abort() as __attribute__((noreturn)). 2015-07-26 12:43:22 +03:00

10f719a830 Add support for fprintf(stderr, ...). 2015-07-26 12:42:53 +03:00

f5cc6fb72d Don't use clang for anything except or1k. 2015-07-26 10:00:58 +03:00
whitequark
d03dabb460 common.mak: Pass -fexceptions to clang and clang++. 
This results in generation of .eh_frame sections. These sections
can be discarded during final linking, or included if exception
handling is desired. For exception handling to work, all sources
must be built with -fexceptions.
 2015-07-26 03:30:21 +03:00
whitequark
69c2a705bf common.mak: use clang/clang++ to compile C/C++ sources. 
Note that -integrated-as is not active by default on OR1K,
so we're still shelling out to binutils to assemble.
It is not yet possible to build everything using -integrated-as.
 2015-07-26 03:28:37 +03:00
whitequark
0f47876d2e common.mak: remove RANLIB. 
`ranlib` is not necessary on any system we can possibly build for,
as it is superseded by `ar s` for the last ten years or so (at least).
Thus, change ar invocations to `ar crs`, also removing a `l` flag
that is ignored by binutils.
 2015-07-26 03:20:23 +03:00
whitequark
f500b906e6 common.mak: remove AS. 
$(AS) was never used: $(assemble) invokes the C compiler instead.
In case of LLVM, this will allow us to consistently use the LLVM
internal assembler for both inline assembly in C and assembly
sources; so, avoid ever invoking binutils as explicitly.

8d1c555e36 misoclib/com/uart: remove irq condition parameters and use "non-full" for tx irq, "non-empty" for rx irq. 
An optimal solution for both sync and async mode is not easy to implement, it would requires moving CDC out of UART module and handling in the PHY with AsyncFIFO or minimal depth.
For now use the solution that works for both cases. We'll try to optimize that if we have performance issues.

ce11b30140 misoclib: integrate mxcrg.py in mlabs_video target, remove others directory 
we should also get rid of mxcrg.v (similar to what is done on papilio or pipstrello)

d0a19c4be8 migen/actorlib/fifo: add FIFO wrapper function 
Allow automatic instantiation of the correct fifo (SyncFIFO or AsyncFIFO) according to the clock domains passed in argument.

d73d75007e misoclib/com/uart: cleanup and add irq condition parameters 
- reintroduce RX/TX split (ease comprehension)
- use FIFO wrapper function from Migen.
- add tx_irq_condition and rx_irq_condition

1f1ff5a5e9 migen/fhdl/tools: fix rename_clock_domain when new == old 
Clock domain renaming should support new == old to allow programmatically determined clock domain renaming.

40740d3ddc litepcie: use optional platform.misoc_path to add litepcie phy wrapper verilog files

097248bce9 uart.c: rx overflow fix and tx simplification 
* fixes the clearing of the rx ringbuffer on rx-overflow
* removes tx_level and tx_cts by restricting the ringbuffer
  to at least one slot empty
* agnostic of the details of the tx irq: works for uarts that
  generate tx interrupts on !tx-full or on tx-empty.
* only rx_produce and tx_consume need to be volatile

35250f5b11 bios: add romboot 
When firmware is small enough, it can be interesting to run code from an embedded blockram memory (faster and not impacted by memory controller activity).
It can also be a fallback option in case boot from flash failed.
To use this, define ROM_BOOT_ADDRESS and initialize the blockram with the firmware data.
