That's because TI_CPTS_MOD (which is the symbol gating the _compilation_ of cpts.c) now depends on PTP_1588_CLOCK, and so is not enabled in these configurations, but TI_CPTS (which is the symbol gating _calls_ to the cpts functions) _is_ enabled. So we end up compiling calls to functions that don't exist, resulting in the linker errors. This patch fixes build errors and restores previous behavior by: - ensure PTP_1588_CLOCK=y in TI specific configs and CPTS will be built - remove TI_CPTS_MOD and, instead, add dependencies from CPTS in TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV as below: config TI_CPSW_SWITCHDEV ... depends on TI_CPTS || !TI_CPTS which will ensure proper dependencies PTP_1588_CLOCK -> TI_CPTS -> TI_CPSW/TI_KEYSTONE_NETCP/TI_CPSW_SWITCHDEV and build type selection. Note. For NFS boot + CPTS all of above configs have to be built-in.
