source: trunk/softs/tsar_boot/platform_fpga_de2-115/platform_fpga.dts @ 276

Last change on this file since 276 was 276, checked in by bouyer, 11 years ago

A boot loader to be stored in ROM of a TSAR platform.
Based on Cesar FUGUET's work.
Platform-specific files are in a subdirectory, e.g. platform_fpga_de2-115,
so the same code can be targetted to different platforms.
The platform is selected with the PLATFORM_DIR environnement variable.
The supported variant are soclib and fpga, the later being the default
and the former selected by defining the SOCLIB environnement variable.
The boot loader embeds a binary device tree describing the platform,
to be used by the loaded software.
