Re: [U-Boot] [PATCH v3] spl: add overall SPL size check

This adds a size check for SPL that can dynamically check generated SPL binaries (including devicetree) for a size limit that ensures this image plus global data, heap and stack fit in initial SRAM.

Since some of these sizes are not available to make, a new host tool 'spl_size_limit' is added that dumps the resulting maximum size for an SPL binary to stdout. This tool is used in toplevel Makefile to implement the size check on SPL binaries.

Some architectures have SPL size checks. CONFIG_SPL_MAX_FOOTPRINT CONFIG_SPL_MAX_SIZE CONFIG_SPL_BSS_MAX_SIZE

Will they be replaced by this new mechanism?
