With the introduction of the production silicon Icicle Kit comes the need to support multiple board device trees. The HSS puts a minimal dtb in it's payload's ancillary-data immediately after U-Boot in memory. CONFIG_OF_BOARD will use this dtb that the HSS carries with the bare minimum of nodes enabled. It allows for firmware to provide the address of the devicetree in memory using the `a1` register. Use the device tree compatible from the hart software services to essentially "detect" which board is in use and therefore select the appropiate device tree for the board. Add a fdt production node to the .its referencing the production Icicle Kit DTB with appropriate attributes. Introduce matching configuration entries to enable selection of the production Icicle kit FDT blob for the MPFS Icicle Production Silicon board. Update the configuration names to match the device tree compatibles for each board configuration. With these updates, change image node and configuration node names with more appropriate names.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
