@dramforever:matrix.orgdramforever just throwing this out there, has anyone tried ubootVisionFive2 without the opensbi override? 11:56:31
@dramforever:matrix.orgdramforeveri have a feeling that the u-boot docs at https://docs.u-boot.org/en/latest/board/starfive/visionfive2.html#building have been written while assuming a non-PIE-capable toolchain11:59:38
@dramforever:matrix.orgdramforeversupport for non-PIE boot was outright removed in opensbi since11:59:53
@dramforever:matrix.orgdramforever* support for non-PIE build was outright removed in opensbi since12:00:00
@dramforever:matrix.orgdramforever the current FW_TEXT_START is effectively a "degree of freedom" in the build where it's basically added to symbols at build and subtracted during relocation, as a convenience for debugging 12:01:23
@dramforever:matrix.orgdramforeverwell by "the opensbi override" i mean https://github.com/NixOS/nixpkgs/blob/53c766aff17166404ccdf31c687ac63eab9f2457/pkgs/misc/uboot/default.nix#L849-L85712:05:12
