SOCFPGA Documentation for U-Boot and SPL
---------------------------------------------
+----------------------------------------
This README is about U-Boot and SPL support for Altera's ARM Cortex-A9MPCore
based SOCFPGA. To know more about the hardware itself, please refer to
www.altera.com.

Here are macro and detailed configuration required to enable DesignWare SDMMC
controller support within SOCFPGA
#define CONFIG_SYS_MMC_MAX_BLK_COUNT 256
-> Using smaller max blk cnt to avoid flooding the limited stack in OCRAM

+--------------------------------------------------
+Generating the handoff header files for U-Boot SPL
+--------------------------------------------------
+
+This text is assuming quartus 16.1, but newer versions will probably work just fine too;
+verified with DE1_SOC_Linux_FB demo project (https://github.com/VCTLabs/DE1_SOC_Linux_FB).
+Updated/working projects should build using either process below.
+
+Note: it *should* work from Quartus 14.0.200 onwards, however, the current vendor demo
+projects must have the IP cores updated as shown below.
+
+Rebuilding your Quartus project
+-------------------------------
+
+Choose one of the follwing methods, either command line or GUI.
+
+Using the comaand line
+~~~~~~~~~~~~~~~~~~~~~~
+
+First run the embedded command shell, using your path to the Quartus install:
+
+ $ /path/to/intelFPGA/16.1/embedded/embedded_command_shell.sh
+
+Then (if necessary) update the IP cores in the project, generate HDL code, and
+build the project:
+
+ $ cd path/to/project/dir
+ $ qsys-generate soc_system.qsys --upgrade-ip-cores
+ $ qsys-generate soc_system.qsys --synthesis=[VERILOG|VHDL]
+ $ quartus_sh --flow compile <project name>
+
+Convert the resulting .sof file (SRAM object file) to .rbf file (Raw bit file):
+
+ $ quartus_cpf -c <project_name>.sof soc_system.rbf
+
+
+Generate BSP handoff files
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+You can run the bsp editor GUI below, or run the following command from the
+project directory:
+
+ $ /path/to/bsb/tools/bsp-create-settings --type spl --bsp-dir build \
+ --preloader-settings-dir hps_isw_handoff/soc_system_hps_0/ \
+ --settings build/settings.bsp
+
+You should use the bsp "build" directory above (ie, where the settings.bsp file is)
+in the following u-boot command to update the board headers. Once these headers
+are updated for a given project build, u-boot should be configured for the
+project board (eg, de0-nano-sockit) and then build the normal spl build.
+
+Now you can skip the GUI section.
+
+
+Using the Qsys GUI
+~~~~~~~~~~~~~~~~~~
+
+1. Navigate to your project directory
+2. Run Quartus II
+3. Open Project (Ctrl+J), select <project_name>.qpf
+4. Run QSys [Tools->QSys]
+ 4.1 In the Open dialog, select '<project_name>.qsys'
+ 4.2 In the Open System dialog, wait until completion and press 'Close'
+ 4.3 In the Qsys window, click on 'Generate HDL...' in bottom right corner
+ 4.3.1 In the 'Generation' window, click 'Generate'
+ 4.3.2 In the 'Generate' dialog, wait until completion and click 'Close'
+ 4.4 In the QSys window, click 'Finish'
+ 4.4.1 In the 'Quartus II' pop up window, click 'OK'
+5. Back in Quartus II main window, do the following
+ 5.1 Use Processing -> Start -> Start Analysis & Synthesis (Ctrl+K)
+ 5.2 Use Processing -> Start Compilation (Ctrl+L)
+
+ ... this may take some time, have patience ...
+
+6. Start the embedded command shell as shown in the previous section
+ 6.1 Change directory to 'software/spl_bsp'
+ 6.2 Prepare BSP by launching the BSP editor from ECS
+ => bsp-editor
+ 6.3 In BSP editor
+ 6.3.1 Use File -> Open
+ 6.3.2 Select 'settings.bsp' file
+ 6.3.3 Click Generate
+ 6.3.4 Click Exit
+
+
+Post handoff generation
+~~~~~~~~~~~~~~~~~~~~~~~
+
+Now that the handoff files are generated, U-Boot can be used to process
+the handoff files generated by the bsp-editor. For this, please use the
+following script from the u-boot source tree:
+
+ $ ./arch/arm/mach-socfpga/qts-filter.sh \
+ <soc_type> \
+ <input_qts_dir> \
+ <input_bsp_dir> \
+ <output_dir>
+
+Process QTS-generated files into U-Boot compatible ones.
+
+ soc_type - Type of SoC, either 'cyclone5' or 'arria5'.
+ input_qts_dir - Directory with compiled Quartus project
+ and containing the Quartus project file (QPF).
+ input_bsp_dir - Directory with generated bsp containing
+ the settings.bsp file.
+ output_dir - Directory to store the U-Boot compatible
+ headers.
+
+This will generate (or update) the following 4 files:
+
+ iocsr_config.h
+ pinmux_config.h
+ pll_config.h
+ sdram_config.h
+
+These files should be copied into "qts" directory in the board directory
+(see output argument of qts-filter.sh command above).
+
+Here is an example for the DE-0 Nano SoC after the above rebuild process:
+
+ $ ll board/terasic/de0-nano-soc/qts/
+ total 36
+ -rw-r--r-- 1 sarnold sarnold 8826 Mar 21 18:11 iocsr_config.h
+ -rw-r--r-- 1 sarnold sarnold 4398 Mar 21 18:11 pinmux_config.h
+ -rw-r--r-- 1 sarnold sarnold 3190 Mar 21 18:11 pll_config.h
+ -rw-r--r-- 1 sarnold sarnold 9022 Mar 21 18:11 sdram_config.h
+
+Note: file sizes will differ slightly depending on the selected board.
+
+Now your board is ready for full mainline support including U-Boot SPL.
+The Preloader will not be needed any more.
