[U-Boot] Broken: U-Boot SPL 2016.01

[U-Boot] Broken: U-Boot SPL 2016.01

[Peter Kümmel]

In 2016.01 SPL is broken on an omap board with DM3730:

U-Boot SPL 2016.01-00076-g72128b2 (Jan 14 2016 - 22:07:33)
wrong hwadapnr: 1075903588


The error message comes from drivers/i2c/omap24xx_i2c.c:


static struct i2c *omap24_get_base(struct i2c_adapter *adap)
{
	switch (adap->hwadapnr) {
	case 0:
		return (struct i2c *)I2C_BASE1;
		break;
	case 1:
		return (struct i2c *)I2C_BASE2;
		break;
#if (I2C_BUS_MAX > 2)
	case 2:
		return (struct i2c *)I2C_BASE3;
		break;
#if (I2C_BUS_MAX > 3)
	case 3:
		return (struct i2c *)I2C_BASE4;
		break;
#if (I2C_BUS_MAX > 4)
	case 4:
		return (struct i2c *)I2C_BASE5;
		break;
#endif
#endif
#endif
	default:
		printf("wrong hwadapnr: %d\n", adap->hwadapnr);
		break;
	}
	return NULL;
}



Has anything changed in the I2C configuration for SPL?

Seems like gd isn't pointing in the right place or looking at garbage or
something.

After disabling CONFIG_EXPERT (and implicitly 
CONFIG_SYS_MALLOC_CLEAR_ON_INIT) it works again.

Seems with for a GCC update from 5.2 to 5.3 this flag is very critical.

Many thanks,
Peter

To be clear, disabling or enabling CONFIG_SYS_MALLOC_CLEAR_ON_INIT ?
