[U-Boot] Altera Arria10 socfpga image usage

[Andre Renaud]

Hi,
Is there a document somewhere describing how to program the Arria10 dev kit
with the u-boot-with-spl.sfp image? This is the image built from the 'next'
branch from http://git.denx.de/?p=u-boot/u-boot-socfpga.git using:
$ make socfpga_arria10_defconfig
$ make

The image is too large to be wrapped up using the Altera mkpimage tool:
$ mkpimage -hv 1 -o u-boot-mkpimage.bin u-boot-with-spl.sfp
Image size must not be more than alignment value of 256 kilobytes

So are the raw u-boot.bin or u-boot-dtb.bin

I've tried writing it either directly into the QSPI flash, onto the base of
an SD card, or into a partition tagged with type 'a2' on an SD card,
starting at sector 2048. None of these seem to work properly.

I am able to build & run the Altera supplied u-boot from https://
github.com/altera-opensource/u-boot-socfpga
<git at github.com:altera-opensource/u-boot-socfpga.git>,
branch socfpga_v2014.10_arria10_bringup.

Thanks,
Andre
