I have a doxygen generated html documentation which was shipped with the hwlib. I did not add this documentation because I suppose it is generated from the doxygen within the files of the hwlib directory. Thus who is interested in it could generate it any time he wants to.

The hwlib directory cotains methods for configuring peripeherals which are within the cores (Altera here talks about the HPS Hard Processor System) and for configuring interaction with the FPGA. Where applicable my BSP code uses the altera methods. But for this BSP the whole FPGA stuff currently is out of scope. > > Is it useful for other BSPs based on Altera SoCs? I could imagine that Altera will have similar hwlibs for other SoCs. But I don't think they can re-use the same hwlib.

I suppose Altera will have a pool of drivers for different IPs, etc. I assume for an SoC they will package those drivers which are applicable into an SoC specific hwlib. And yes, of course we could possibly slice out single drivers and share them between BSPs. The problem here would be maintenance. Once Altera releses a new version of the original hwlib this would mean a lot of manual work. My approach here is more simple: Adding the whole hwlib is a commit of it's own. If a new version of hwlib gets released, only this one commit will need updating. > > On 3/7/2014 7:59 AM, Ralf Kirchner wrote: >> Add hwlib as copied from Altera >> --- >> .../hwlib/include/alt_16550_uart.h | 1555 + >> .../hwlib/include/alt_address_space.h | 390 + >> .../hwlib/include/alt_bridge_manager.h | 269 + >> .../hwlib/include/alt_clock_group.h | 95 + >> .../hwlib/include/alt_clock_manager.h | 1431 + >> .../arm/altera-cyclone-v/hwlib/include/alt_dma.h | 940 + >> .../hwlib/include/alt_dma_common.h | 162 + >> .../hwlib/include/alt_dma_program.h | 949 + >> .../hwlib/include/alt_fpga_manager.h | 1052 + >> .../hwlib/include/alt_generalpurpose_io.h | 1236 + >> .../altera-cyclone-v/hwlib/include/alt_globaltmr.h | 458 + >> .../hwlib/include/alt_hwlibs_ver.h | 52 + >> .../hwlib/include/alt_interrupt_common.h | 531 + >> .../hwlib/include/alt_mpu_registers.h | 156 + >> .../hwlib/include/alt_reset_manager.h | 249 + >> .../hwlib/include/alt_system_manager.h | 209 + >> .../altera-cyclone-v/hwlib/include/alt_timers.h | 677 + >> .../altera-cyclone-v/hwlib/include/alt_watchdog.h | 779 + >> .../arm/altera-cyclone-v/hwlib/include/hwlib.h | 190 + >> .../hwlib/include/socal/alt_acpidmap.h | 3569 + >> .../altera-cyclone-v/hwlib/include/socal/alt_can.h |36873 +++++++ >> .../hwlib/include/socal/alt_clkmgr.h | 6464 ++ >> .../altera-cyclone-v/hwlib/include/socal/alt_dap.h | 144 + >> .../hwlib/include/socal/alt_dmanonsecure.h | 144 + >> .../hwlib/include/socal/alt_dmasecure.h | 144 + >> .../hwlib/include/socal/alt_emac.h |103305 >> ++++++++++++++++++ >> .../altera-cyclone-v/hwlib/include/socal/alt_f2h.h | 1075 + >> .../hwlib/include/socal/alt_fpgamgr.h | 7090 ++ >> .../hwlib/include/socal/alt_fpgamgrdata.h | 158 + >> .../hwlib/include/socal/alt_gpio.h | 1991 + >> .../altera-cyclone-v/hwlib/include/socal/alt_h2f.h | 1073 + >> .../altera-cyclone-v/hwlib/include/socal/alt_i2c.h | 5940 + >> .../altera-cyclone-v/hwlib/include/socal/alt_l3.h | 6299 ++ >> .../hwlib/include/socal/alt_l4wd.h | 1801 + >> .../hwlib/include/socal/alt_lwfpgaslvs.h | 52 + >> .../hwlib/include/socal/alt_lwh2f.h | 1450 + >> .../hwlib/include/socal/alt_mpul2.h | 144 + >> .../hwlib/include/socal/alt_mpuscu.h | 144 + >> .../hwlib/include/socal/alt_nand.h |10617 ++ >> .../hwlib/include/socal/alt_nanddata.h | 52 + >> .../hwlib/include/socal/alt_ocram.h | 52 + >> .../hwlib/include/socal/alt_qspi.h | 5951 + >> .../hwlib/include/socal/alt_qspidata.h | 52 + >> .../altera-cyclone-v/hwlib/include/socal/alt_rom.h | 52 + >> .../hwlib/include/socal/alt_rstmgr.h | 3382 + >> .../hwlib/include/socal/alt_scanmgr.h | 927 + >> .../hwlib/include/socal/alt_sdmmc.h | 9115 ++ >> .../altera-cyclone-v/hwlib/include/socal/alt_sdr.h | 4149 + >> .../hwlib/include/socal/alt_spim.h | 3293 + >> .../hwlib/include/socal/alt_spis.h | 2958 + >> .../altera-cyclone-v/hwlib/include/socal/alt_stm.h | 144 + >> .../hwlib/include/socal/alt_sysmgr.h |24810 +++++ >> .../altera-cyclone-v/hwlib/include/socal/alt_tmr.h | 864 + >> .../hwlib/include/socal/alt_uart.h | 5158 + >> .../altera-cyclone-v/hwlib/include/socal/alt_usb.h |114043 >> ++++++++++++++++++++ >> .../arm/altera-cyclone-v/hwlib/include/socal/hps.h | 8026 ++ >> .../altera-cyclone-v/hwlib/include/socal/socal.h | 356 + >> .../hwlib/src/hwmgr/alt_16550_uart.c | 1179 + >> .../hwlib/src/hwmgr/alt_address_space.c | 184 + >> .../hwlib/src/hwmgr/alt_bridge_manager.c | 189 + >> .../hwlib/src/hwmgr/alt_clock_manager.c | 5208 + >> .../arm/altera-cyclone-v/hwlib/src/hwmgr/alt_dma.c | 2806 + >> .../hwlib/src/hwmgr/alt_dma_program.c | 1043 + >> .../hwlib/src/hwmgr/alt_fpga_manager.c | 999 + >> .../hwlib/src/hwmgr/alt_generalpurpose_io.c | 745 + >> .../hwlib/src/hwmgr/alt_globaltmr.c | 529 + >> .../hwlib/src/hwmgr/alt_reset_manager.c | 135 + >> .../hwlib/src/hwmgr/alt_system_manager.c | 265 + >> .../altera-cyclone-v/hwlib/src/hwmgr/alt_timers.c | 1292 + >> .../hwlib/src/hwmgr/alt_watchdog.c | 1026 + >> > -- -------------------------------------------- Embedded Brains GmbH Ralf Kirchner Dornierstr. 4 D-82178 Puchheim Germany email: ralf.kirch...@embedded-brains.de Phone: +49(0)89/1894741-17 Fax: +49(0)89/1894741-08 Diese Nachricht ist keine geschäftliche Mitteilung im Sinne des EHUG. _______________________________________________ rtems-devel mailing list rtems-devel@rtems.org http://www.rtems.org/mailman/listinfo/rtems-devel
