Where is 2/2 patch ?

The commit message should say "socfpga: Update README with handoff generation instructions", the rest is just fluff . And btw. those instructions came from my internal notes ;-)

From v2-U-Boot-arm-socfpga-Add-SoCFPGA-SR1500-board limbo patch series describing SR1500 SPL generation (updates in following patch).

The body should contain a description of what this patch adds, not where this came from.

+------------------------------------------------------------------------- +Generating the header files for SPL intergration as a replacement for the +Preloader +------------------------------------------------------------------------- +This text assumes the use of Quartus 14.0.200

Works in Quartus 16.1 too, so we can reword this as "Altera Quartus 14.0 or newer" .

+I) Rebuilding the MCVEVK Quartus project +----------------------------------------

• 1. Navigate to DENX_MCV_reference_* directory

You should replace all the DENX_MCV_reference_ stuff with "Quartus project direcory"

• 2. Run Quartus II
• 3. Open Project (Ctrl+J), select DENX_MCV_reference.qpf

Select the Quartus project .qpf file ...

• 4. Run QSys [Tools->QSys]
• 4.1) In the Open dialog, select 'mcv_hps.qsys'

Open the qsys system file .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 a while, so wait.

• ... have lunch, coffee, play games ...
• [
• NOTE: Steps 2-5 above can be also done using a convenience scripts

•     from the command line:
  

• $ ./qsys.sh && ./anal.sh && ./build.sh
  

• ]

Drop this, the scripts are not available.

• 6. Launch a separate terminal window
• 6.1) Change directory to 'software/spl_bsp'
• 6.2) Export path to embedded command shell and friends

•     $ export PATH=/work/DENX/Altera/Quartus/14.0/embedded/:$PATH
  

This path points to Quartus embedded command shell directory, so update it to PATH=/path/to/Altera/Quartus/14.0/embedded/ or something.

• 6.3) Start embedded command shell (ECS)

•     $ embedded_command_shell.sh
  

• 6.4) Prepare BSP by launching the BSP editor from ECS

•     => bsp-editor
  

• 6.5) In BSP editor

•     6.5.1) Use File -> Open
  

• 6.5.2) Select 'settings.bsp' file
  

• 6.5.4) Click Generate
  

• 6.5.5) Click Exit
  

+Now the necessary files are generated. And U-Boot can be used to generate +the SPL header files. For this, please use the following script from the +u-boot source tree::

Extra colon, drop it. Also, I think qts-filter was update to support more options....

• $ ./arch/arm/mach-socfpga/qts-filter.sh [soc_type] [input_qts_dir] [input_bsp_dir] [output_dir]
• Process QTS-generated headers 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 the following 4 files:

+iocsr_config.h +pinmux_config.h +pll_config.h +sdram_config.h

+These files need to be copied into "qts" directory in the board directory +(see output arg of script command above).

argument instead of arg?

+Here the example for the DENX MCVEVK:

This example should use some more generic board, like CV SoCDK

+$ ll board/denx/mcvevk/qts/ +total 44 +drwxrwxr-x 2 stefan stefan 4096 Okt 20 07:07 ./ +drwxrwxr-x 3 stefan stefan 4096 Okt 21 13:06 ../ +-rw-rw-r-- 1 stefan stefan 8826 Okt 20 07:07 iocsr_config.h +-rw-rw-r-- 1 stefan stefan 4398 Okt 20 07:07 pinmux_config.h +-rw-rw-r-- 1 stefan stefan 3192 Okt 20 07:07 pll_config.h +-rw-rw-r-- 1 stefan stefan 9031 Okt 20 07:07 sdram_config.h

+Now your board is ready for full mainline support including +U-Boot SPL. The Preloader will not be needed any more.
