| Altera SOCFPGA Arria10 FPGA Manager |
| |
| Required properties: |
| - compatible : should contain "altr,socfpga-a10-fpga-mgr" |
| - reg : base address and size for memory mapped io. |
| - The first index is for FPGA manager register access. |
| - The second index is for writing FPGA configuration data. |
| - resets : Phandle and reset specifier for the device's reset. |
| - clocks : Clocks used by the device. |
| - altr,bitstream : Fit image file name for both FPGA peripheral bitstream, |
| FPGA core bitstream and full bitstream. |
| |
| Full bitstream, consist of peripheral bitstream and core |
| bitstream. |
| |
| FPGA peripheral bitstream is used to initialize FPGA IOs, |
| PLL, IO48 and DDR. This bitstream is required to get DDR up |
| running. |
| |
| FPGA core bitstream contains FPGA design which is used to |
| program FPGA CRAM and ERAM. |
| |
| Example: Bundles both peripheral bitstream and core bitstream into FIT image |
| called fit_spl_fpga.itb. This FIT image can be created through running |
| this command: tools/mkimage |
| -E -p 400 |
| -f board/altera/arria10-socdk/fit_spl_fpga.its |
| fit_spl_fpga.itb |
| |
| For details of describing structure and contents of the FIT image, |
| please refer board/altera/arria10-socdk/fit_spl_fpga.its |
| |
| - Examples for booting with full release or booting with early IO release, then |
| follow by entering early user mode: |
| |
| fpga_mgr: fpga-mgr@ffd03000 { |
| compatible = "altr,socfpga-a10-fpga-mgr"; |
| reg = <0xffd03000 0x100 |
| 0xffcfe400 0x20>; |
| clocks = <&l4_mp_clk>; |
| resets = <&rst FPGAMGR_RESET>; |
| altr,bitstream = "fit_spl_fpga.itb"; |
| }; |
