Hei hei,
every now and then some user wants to build without having to install OpenSSL development libraries on the build host for different reasons. This is not possible for all boards supported by U-Boot and not for all configurations, but at least for some. And U-Boot has an option for that, which currently does not work.
The topic was discussed multiple times and multiple patches were proposed to fix things, but to my knowledge none got applied. I'm aware of at least the discussions listed below.
This series is based on the work done by Paul-Erwan Rio earlier this year, but replacing the first of two patches by a new patch based on two older approaches from 2021 and 2022 and the feedback they got. Because of that, I gave it the v2 right away.
I added some notes to both patches for further explanations on my decisions.
I tested this with and without libssl-dev installed on a Debian GNU/Linux 12 (bookworm) host (amd64 arch), with buildman and the following options:
buildman -b master..mybranch -a '~CONFIG_TOOLS_KWBIMAGE' -a '~CONFIG_TOOLS_LIBCRYPTO' atmel
And with libssl-dev installed this:
buildman -b master..mybranch atmel buildman -b master..mybranch turris
Building 'turris' without libssl-dev installed fails as expected.
The series solves _my_ immediate problem (building a recent U-Boot for an at91 based board _without_ FIT images and/or signing, in a BSP from 2018 which we can not update, and which does not handle host openssl correctly), but I did not investigate other combinations, except those listed above. Test on real hardware was only on our at91 based boards.
Please test and let me know what you think. I can imagine having CI testing builds with and without CONFIG_TOOLS_LIBCRYPTO set might be difficult, because building without won't work for every board. It can not, because some boards require it while others don't.
