[PATCH 0/2] Fix COMPILE_TEST dependencies for CPM uart, TSA and QMC

[Herve Codina]

This series fixes issues raised by the kernel test robot
  https://lore.kernel.org/oe-kbuild-all/202305160221.9XgweObz-lkp@intel.com/

In COMPILE_TEST configurations, TSA and QMC need CONFIG_CPM to be set in
order to compile and CPM uart needs CONFIG_CPM2.

Best regards,
Hervé

[PATCH 1/2] soc: fsl: cpm1: Fix TSA and QMC dependencies in case of COMPILE_TEST

[Herve Codina]

In order to compile tsa.c and qmc.c, CONFIG_CPM must be set.

Without this dependency, the linker fails with some missing
symbols for COMPILE_TEST configurations that need QMC without
enabling CPM.

[PATCH 2/2] serial: cpm_uart: Fix a COMPILE_TEST dependency

[Herve Codina]

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.

Ah, perfect. Greg, please disregard my revert posted at:
   https://lore.kernel.org/all/20230518055620.29957-1-jirislaby@kernel.org/

and take these instead.

Thanks.

Actually, does this makes sense? I mean, the last part after "||" is now 
superfluous and doesn't help anything, right?

Indeed, I will remove all the (PPC32 && CPM2 && COMPILE_TEST) in the next
iteration.
I will also remove the '#elif defined(CONFIG_COMPILE_TEST)' case in the
cpm_uart.h file.
