Yes, a simple C tool to take an existing PBL or RCW dump and "espi-ize" it into a PBL dump would be nice. The user will still need to acquire the existing RCW manually. This only needs to be done once on a board; it's not part of building a U-Boot image.
[Xie Shaohui] A simple C tool will make things more complex, the pbl_image_tool does the same thing
It doesn't do the same thing for poeple who don't have access to it.
Plus, requiring the user to do a bunch of manual stuff is not "the same thing" as something more automated.
More work for us upfront is not the same as "more complex".
and it is irreplaceable,
Tell that to the people trying to replace it with some big Eclipse-based thing. :-)
something like RCW has to be produced manually, and because there is no near-universal default RCW, this README took a basic assumption that user already can boot from NOR flash, so user can reuse the RCW dump of NOR u-boot with change "PBI_SRC" and "BOOT_LOC" only.
Yes. But once the user provides an RCW, everything else should be automatable.
