For non-SPL/TPL setups dm-spl, dm-tpl, dm-pre-proper, dm-pre-reloc are
handled equally, forcing the nodes with these properties
to be accessible and device being probed
before pre-relocation of U-Boot proper (drivers/core/util.c):
bool ofnode_pre_reloc(ofnode node)
{
/* for SPL and TPL the remaining nodes after the fdtgrep 1st pass
* had property dm-pre-reloc or u-boot,dm-spl/tpl.
* They are removed in final dtb (fdtgrep 2nd pass)
*/
return true;
if (ofnode_read_bool(node, "u-boot,dm-pre-reloc"))
return true;
if (ofnode_read_bool(node, "u-boot,dm-pre-proper"))
return true;
/*
* In regular builds individual spl and tpl handling both
* count as handled pre-relocation for later second init.
*/
if (ofnode_read_bool(node, "u-boot,dm-spl") ||
ofnode_read_bool(node, "u-boot,dm-tpl"))
return true;
return false;
}
Howewer, to avoid confusion in future, replace dm-spl
`%s/dm-spl/dm-pre-proper/g` properties to dm-pre-proper
to explicitly state that they are handled during pre-relocation
stage of U-Boot proper.
