Subject: kconfig: use distinct tokens for type and default properties
X-Git-Url: https://jxself.org/git/?a=commitdiff_plain;h=89d9fc0b2c28b1699ebfaeacde69aad688a2893a;p=carl9170fw.git

kconfig: use distinct tokens for type and default properties

This commit removes kconf_id::stype to prepare for the entire
removal of kconf_id.c

To simplify the lexer, I want keywords straight-mapped to tokens.
