Florent Kermarrec c55199deb9 misoclib/soc: add _integrated_ to cpu options to avoid confusion 2015-03-21 20:51:37 +01:00
Florent Kermarrec 711540e15c targets/mlabs_video: rename sdram_module to sdram_modules to reflect that we have 2 modules sharing the same characteristics 2015-03-21 18:10:56 +01:00
Florent Kermarrec 1c0e306176 targets/kc705: rename sdram_module to sdram_modules to reflect that we have 8 modules sharing the same characteristics 2015-03-21 18:07:10 +01:00
Florent Kermarrec 52924ee1f2 sdram: define MT46V32M16/MT8JTF12864 and use it on pipistrello/kc705 2015-03-21 17:25:36 +01:00
Florent Kermarrec fd2f8d4bb4 sdram: define MT46V32M16 and use it on m1/mixxeo 2015-03-21 17:04:58 +01:00
Florent Kermarrec de2f1c31d5 sdram: create module.py to define SDRAM modules and use it on de0nano/ppro targets 2015-03-21 16:56:53 +01:00
Florent Kermarrec 6e4b7c6cfd sdram: split sdram_timing in sdram_timing_settings/sdram_controller_settings 
req_queue_size, read_time, write_time settings are not sdram_timing settings but sdram controller settings
 2015-03-21 12:55:39 +01:00
Robert Jordens ec465959d0 pipistrello: add user reset 
apparently needed for flashed bitstream, xiped bios, mor1kx
 2015-03-19 19:01:06 +01:00
Robert Jordens a10875a3b7 pipistrello: fix flash, ddram pin naming 2015-03-19 19:01:06 +01:00

Florent Kermarrec b2f32ad124 targets/simple: manual instantiation of CRG (automatic insertion works for BaseSoC but not for MiniSoC since this one define clock_domains) 2015-03-17 01:07:44 +01:00
Florent Kermarrec 28d04ec300 soc: rename with_sdram option to with_main_ram (with_sdram was confusing) 2015-03-14 00:49:19 +01:00
Sebastien Bourdeauducq d09529d483 targets/simple: use mibuild default clock 2015-03-14 00:11:59 +01:00

Florent Kermarrec e133777450 targets/simple: add MiniSoC 2015-03-06 10:10:58 +01:00
Florent Kermarrec 95fa753149 liteeth: add phy autodetect function (phy can still be instanciated directly) 2015-03-06 10:10:34 +01:00
Florent Kermarrec 2b9397ff5b targets: do not implement sdram if already provided by SoC (allow use of -Ot with_sdram = True) 2015-03-06 07:56:45 +01:00
Florent Kermarrec 0716dadaf2 targets: keep the SPI flash core even if with_rom is enabled, so that flash booting in the BIOS still works 2015-03-03 10:39:31 +01:00
Florent Kermarrec 02ef1dc95a targets: fix mlabs_video FramebufferSoC 2015-03-02 18:38:43 +01:00
Florent Kermarrec 473997df26 cpuif: add CSR_ prefix to CSR base addresses (avoid conflicts between CSR and mems bases) 2015-03-02 16:52:17 +01:00
Florent Kermarrec de698c51e4 sdram: rename self.phy_settings to self.settings (using phy.settings instead of phy.phy_settings seems cleaner) 2015-03-02 11:29:43 +01:00
Robert Jordens 93b80b2f1c pipistrello: fix lpddr parameters, crg, flash, style 2015-02-28 16:17:34 -07:00

Florent Kermarrec 6107b7844a test implementation on all targets and fix issues 2015-02-28 12:04:51 +01:00
Florent Kermarrec 1366ff5e26 move mxcrg to others (we should integrate it in mlabs_video.py and remove the verilog file in the future) 2015-02-28 11:51:51 +01:00
Florent Kermarrec 69e869893d remane GenSoC to SoC (more coherent and we will add support for multiple SoCs with their own Wisbbone/CSR buses in the future) 2015-02-28 11:36:15 +01:00
Florent Kermarrec 2c51adcd68 misoclib: better organization (create cores categories: cpu, mem, com, ...) 2015-02-28 09:40:44 +01:00
Florent Kermarrec 074f576340 targets: add de0nano (100MHz, integrated bios and SDRAM) 2015-02-27 19:47:32 +01:00
Florent Kermarrec 5e2e9338d2 bios: we can now use -Ot with_rom True on targets to force bios implementation in integrated rom (can speed up debug we don't want to reflash SPI or NOR flash) 2015-02-27 17:22:44 +01:00
