DE10-nano HPS boot from EPCS

Hi Hang​ 

The 2 pages from rocketboard already been obsolete if you're using a newer uboot/quartus version. You should refer to this page instead https://www.rocketboards.org/foswiki/Documentation/BuildingBootloaderCycloneVAndArria10

or this : https://altera-fpga.github.io/rel-25.3/embedded-designs/cyclone-v/sx/soc/boot-examples/ug-linux-boot-cve-soc/

Any changes using bsp-editor will not take effect anymore , and later version SOC EDS also become obsolete and no longer using.

When building uboot, don't use the default make socfpga_cyclone5_defconfig as it is for the cyclone5 devkit, instead use the one for de0 nano (Socfpga_de10_nano_defconfig) . All the modification is to be done in defconfig or the devicetree file or .config

Thanks

Regards

Kian
