York,
ok - will give it a try tomorrow.
hmm - having a look at the Makefile it looks like I need CONFIG_FSL_DDR2.
This seems to pull in the "new" code ... without omitting the "old" one
in arch/powerpc/cpu/mpc83xx/spd_sdram.c
The Makefile further uses ctrl_regs.c ... which fails.
having a look arch/powerpc/cpu/mpc8xxx/ddr/ctrl_regs.c gives :
#ifdef CONFIG_MPC85xx
#define _DDR_ADDR CONFIG_SYS_MPC85xx_DDR_ADDR
#elif defined(CONFIG_MPC86xx)
#define _DDR_ADDR CONFIG_SYS_MPC86xx_DDR_ADDR
#else
#error "Undefined _DDR_ADDR"
#endif
There's not a single sign of any 83xx within this code.
Grepping through the board configs only show 85xx and 86xx based boards using it.
Sorry, but I'm feeling like an idiot.
Are you playing some game with me or am I simply unable to understand the code ?
Please shed some light on this.
Andre,
I am sorry I totally ignored the subject with mpc83xx. I was thinking of mpc85xx.
You are right the old code is in spd_sdram.c and it is still in use for mpc83xx. Unless to adjust the code, there is no board specific file.
