sconfig: Allow strings in devicetree.cb
Currently you cannot assign a string to a register in devicetree because the quotes are removed when parsing and the literal is assigned directly. Add a parse option for two double-quotation marks to indicate a string and return a quoted literal that can be assigned to a register with a 'const char *' type. Example: chip drivers/i2c/generic register "hid" = ""INT343B"" register "uid" = "1" device i2c 15 on end end Change-Id: I621cde1f7547494a8035fbbab771f29522da1687 Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/14787 Tested-by: build bot (Jenkins) Reviewed-by: Aaron Durbin <adurbin@chromium.org>
