Patch Case#: 391502
//****************************************************************

Description:

To enhance the compatibility of early IO release by using CDRATIO1
when sending the sync packet. The sync is needed after programming
periph RBF. This resolve incident where early IO release failed when
certain IO banks are used for FPGA config.


Guide:
Note that the patch will patch U-Boot source only but not tools.
Hence customer would need follow the steps as below.

1. Run 'soceds-16.0-0.03soc-linux.run' and select ~/altera/16.0/ as install directory
2. Go to ~/altera/16.0/embedded/examples/hardware/a10_soc_devkit_ghrd/ and rebuild the GHRD
3. Run bsp-editor and create new .../software/uboot_bsp/ project
4. Edit .../software/uboot_bsp/devicetree.dts with
        chosen {
        cff-file = "ghrd_10as066n2.periph.rbf"; /* only for SD boot */
        early-release-fpga-config;
        }
5. Run 'make' in .../software/uboot_bsp/ and dd uboot_w_dtb-mkpimage.bin to A2 partition of the sd card
6. Go to .../output_files/ directory and run this command
  $ quartus_cpf -c --hps -o bitstream_compression=on ghrd_10as066n2.sof ghrd_10as066n2.rbf
7. Update the RBF binary on the target
8. Boot devkit and see successful early I/O release message in uboot output. 
  See core RBF loaded during uboot 'autoboot' before Linux is loaded.

If you are using QSPI and NAND boot, you need to use quartus_hps to update the QSPI content.
For QSPI and NAND flash, periph.rbf is located at flash offset 0x72_0000 while core.rbf at 0x82_0000
Please refer SOCEDS user guide chapter 9 to learn more about quartus_hps

Caution - You must either have previously installed the
          SoC Embedded Design Suite (EDS) 16.0 software or must
          install the SoC Embedded Design Suite (EDS) 16.0 software
          before installing this patch. Otherwise, the patch will
          not be installed correctly and the SoC Embedded Design Suite (EDS)
          software will not run properly.
