When using #define CONFIG_SOME_OPTION, the value it set to '1'. When using defconfig (i.e. CONFIG_SOME_OPTION=y) the value is set to 'y'. This results in differences showing up with -K. These differences are seldom useful.
Adjust buildman to suppress these differences by default.

This tells buildman to configuration U-Boot and create the .cfg files, but not actually build the source. This is 5-10 times faster than doing a full build.
+By default buildman considers the follow two configuration methods +equivalent: + + #define CONFIG_SOME_OPTION + + CONFIG_SOME_OPTION=y + +The former would appear in a header filer and the latter in a defconfig +file. The achieve this, buildman considers 'y' to be '1' in configuration +variables. This avoids lots of useless output when converting a CONFIG +option to Kconfig. To disable this behaviour, use --squash-config-y. +
