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
