[U-Boot-Users] [PATCH] SPI relocation fix

Already did

cpu/mpc8xx/cpu_init.c

#if defined(CFG_MPC8XX_RELOCATION_UPATCH)
        cpm_load_patch (immr);  /* load mpc8xx  microcode patch */
#endif

The condition for which this is defined as follows, which is not
behaving according to your idea.

if defined(CFG_MPC850_SMC_UPATCH)     || \
    defined(CFG_MPC850_I2C_SPI_UPATCH) || \
    defined(CFG_MPC850_I2C_SMC_UPATCH) || \
    defined(CFG_MPC850_SPI_SMC_UPATCH) || \
    defined(CFG_MPC860_SMC_UPATCH)     || \
    defined(CFG_MPC860_I2C_SPI_UPATCH) || \
    defined(CFG_MPC860_I2C_SMC_UPATCH) || \
    defined(CFG_MPC860_SPI_SMC_UPATCH)

#  define CFG_MPC8XX_RELOCATION_UPATCH   1
#endif
