[U-Boot] [PATCH 1/1] avb2.0: add proper dependencies to libavb
Provide proper dependencies for LIBAVB: (FASTBOOT and !BLK): 1. CONFIG_FASTBOOT is needed, as fastboot buffer is re-used (which is initially used in the fastboot protocol for downloads) 2. !CONFIG_BLK, as current implementation currently doesn't support non-legacy block API.

Hi Igor,
Thanks for the fix. See my comments below.

Since libavb library alone is highly portable (it compiles fine with several compilers), I'm not sure if's the best choice to make it dependent on FASTBOOT (obviously it is not dependent on it). The dependency is rather introduced by commit 3af30e4443aa ("avb2.0: implement AVB ops"), which re-uses CONFIG_LIBAVB Kconfig symbol to wire common/avb_verify.c to Kbuild.
So, unless you have some counter-proposal, I vote for adding a new Kconfig symbol for common/avb_verify.c, which then can be marked as dependent on FASTBOOT. This will also keep the hopes alive about testing libavb on sandbox.
Thanks, Eugeniu.
Hi Eugeniu,
Makes sense, will re-send this patch soon with changes based on your suggestions. Thanks
Regards, Igor
