I don't like #ifdefs in common code, either, but I think in this case
it's still an improvement. What do you think about this:
static inline u8 i2c_reg_read(u8 addr, u8 reg)
{
u8 buf;
#ifdef CONFIG_8xx
/* MPC8xx needs this. Maybe one day we can get rid of it. */
i2c_init(CONFIG_SYS_I2C_SPEED, CONFIG_SYS_I2C_SLAVE);
#endif
#ifdef DEBUG
printf("%s: addr=0x%02x, reg=0x%02x\n", __func__, addr, reg);
#endif
#ifdef CONFIG_BLACKFIN
/* This ifdef will become unneccessary in a future version of the
* blackfin I2C driver.
*/
i2c_read(addr, reg, 0, &buf, 1);
#else
i2c_read(addr, reg, 1, &buf, 1);
#endif
return buf;
}
