Only putting qixis.c in ifndef CONFIG_SPI_BUILD may not work for
9132QDS. following change is also required i.e. to put CONFIG_ID_EEPROM
in ifndef CONFIG_SPI_BUILD
+ifndef CONFIG_SPL_BUILD
COBJS-$(CONFIG_FSL_QIXIS) += qixis.o
-COBJS-$(CONFIG_PQ_MDS_PIB) += pq-mds-pib.o
COBJS-$(CONFIG_ID_EEPROM) += sys_eeprom.o
+endif
+COBJS-$(CONFIG_PQ_MDS_PIB) += pq-mds-pib.o
It will be good to have original patch which do not compile any file for
SPL. if any file needs to be compiled for SPL, it can be added in ifdef
MINIMAL.
If we follow "ifndef CONFIG_SPL_BUILD" way, one has to add required
define one by one for required platforms supporting SPL. It eventually
may become equal to my original patch. (just guessing, it may never happen)
