In a COMPILE_TEST configuration, the cpm_uart driver uses symbols from the cpm_uart_cpm2.c file. This file is compiled only when CONFIG_CPM2 is set. Without this dependency, the linker fails with some missing symbols for COMPILE_TEST configuration that needs SERIAL_CPM without enabling CPM2. This lead to: depends on CPM2 || CPM1 || (PPC32 && CPM2 && COMPILE_TEST) This dependency does not make sense anymore and can be simplified removing all the COMPILE_TEST part.
