util/spd_tools: Implement a unified version of the spd_gen tool
Currently there are two versions of spd_tools: one for LP4x and one for DDR4. This change is the first step in unifying these into a single tool. This change implements a unified version of the spd_gen tool, by combining the functionality currently in lp4x/gen_spd.go and ddr4/gen_spd.go. The unified version takes the memory technology as an argument, and generates SPD files for all platforms supporting that technology. BUG=b:191776301 TEST=Compare the SPDs generated by the old and new versions of the tool for all supported platforms. For reference, the test script used is here: https://review.coreboot.org/c/coreboot/+/57511 Signed-off-by: Reka Norman <rekanorman@google.com> Change-Id: I7fc036996dbafbb54e075da0c3ac2ea0886a6db2 Reviewed-on: https://review.coreboot.org/c/coreboot/+/57512 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Reviewed-by: Tim Wawrzynczak <twawrzynczak@chromium.org> Reviewed-by: Karthik Ramasubramanian <kramasub@google.com> Reviewed-by: Michael Niewöhner <foss@mniewoehner.de>
