Florent Kermarrec a1e4183b3f sdram/phy/s6ddrphy: fix comment on S6QuarterRateDDRPHY 2015-08-22 12:50:41 +02:00
Florent Kermarrec de87d65f68 sdram/module: add P3R1GE4JGF DDR2 (Atlys) and MT41J128M16 DDR3 (Opsis, Novena) modules. 2015-08-22 12:42:44 +02:00
Florent Kermarrec 50e857e99c sdram/phy/s6ddrphy: add S6QuarterRateDDRPHY to run DDR3 at higher frequencies. 
Built on top of S6HalfRateDDRPHY, exposes a 4 phases DFI interface to the controller with a 2x slower clock.
Validated on the Numato Lab opsis board (50MHz sys_clk/ DDR400), should also work on the Novena laptop (same DDR3 module).

Florent Kermarrec 8bb30a8620 liteeth/phy: fix autodetect (clk_freq not necessary passed in kwargs) 2015-08-22 12:08:49 +02:00
Florent Kermarrec 158fbe49ac sdram/phy/s6ddrphy: rename S6DDRPHY to S6HalfRateDDRPHY and use ORed wrdata_en/rddata_en (the controller already manages that) 2015-08-22 11:47:26 +02:00

Florent Kermarrec 3cf46671e9 liteeth/phy: rename rgmii to s6rgmii since specific to Spartan6 
Also remove autodetection support for RGMII. For it to work we would need to pass the device we are building for.

Florent Kermarrec 52fba05e26 sdram/phy/initsequence: add burst chop 4 (BC4) for DDR3 
This is needed for half rate controllers with burst length of 4.
For best efficiency quarter rate controllers should be used.

whitequark 8db098dd8f Make sure the BIOS file ends on an aligned boundary. 
If it does not, the address to which mkmscimg.py writes the CRC
and the address from which it is read could differ.

Florent Kermarrec 405efc5560 update lm32 with "Switch to -fPIC" changes. 2015-07-28 11:11:11 +02:00
whitequark 03ebc736b2 Pass -integrated-as to clang. 
This avoids misdetection of target assembler by clang.

whitequark 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.
