Why would CONFIG_A003399_NOR_WORKAROUND be enabled if
CONFIG_SYS_FSL_ERRATUM_IFC_A003399 isn't?
originally i tried the same but it did not work. As P1010RDB.h does
not include config_mpc85xx.h. Only arch/powerpc/cpu/mpc85xx/*.c
files includes both P1010RDB.h and config_mpc85xx.h
Can you add #include <config.h> in P1010RDB.h near the top, but
after the symbols that config_mpc85xx.h depends on (which I think is
just CONFIG_P1010)?
I need to add config_mpc85xx.h here.
#define CONFIG_MPC85xx
#define CONFIG_FSL_IFC /* Enable IFC Support */
#define CONFIG_SYS_HAS_SERDES /* common SERDES init code */
+#include "../../arch/powerpc/include/asm/config_mpc85xx.h"
I tried just after CONFIG_P1010 but it is giving compilation error.
What error?
Just to mention, I need to provide relative path in order to compile.
What specifically did you try and what error did it produce?
I will still suggest to keep original patch, As header file location
may change over period of time then config file needs to be updated
again.
No, this has been a repeated problem (not having access to
config_mpc85xx.h in the board config file) and I'd like to see it fixed.
