This avoids lots of useless output when converting a CONFIG option to Kconfig. To disable this behaviour, use --squash-config-y. +Checking the environment +======================== + +When converting CONFIG options which manipulate the default environment, +a common requirement is to check that the default environment has not +changed due to the conversion. Buildman supports this with the -U option, +used after a build. This shows differences in the default environment +between one commit and the next. + +For example: + +$ buildman -b squash brppt1 -sU +boards.cfg is up to date. Nothing to do. +Summary of 2 commits for 3 boards (3 threads, 3 jobs per thread) +01: Migrate bootlimit to Kconfig +02: Squashed commit of the following: + c brppt1_mmc: altbootcmd=mmc dev 1; run mmcboot0; -> mmc dev 1; run mmcboot0 + c brppt1_spi: altbootcmd=mmc dev 1; run mmcboot0; -> mmc dev 1; run mmcboot0 + + brppt1_nand: altbootcmd=run usbscript + - brppt1_nand: altbootcmd=run usbscript +(no errors to report) + +This shows that commit 2 modified the value of 'altbootcmd' for 'brppt1_mmc' +and 'brppt1_spi', removing a trailing semicolon. 'brppt1_nand' gained an a +value for 'altbootcmd', but lost one for ' altbootcmd'. + +The -U option uses the u-boot.env files which are produced by a build. + Other options ============= |
