[U-Boot] A question about unconfigured pads check in omap24xx_i2c

[Nikita Kiryanov]

In drivers/i2c/omap24xx_i2c.c there are a few checks that attempt to
detect unconfigured pads for the i2c bus in use. These checks are
all in the form of

if (status == I2C_STAT_XRDY) {
	printf("unconfigured pads\n");
	return -1;
}

This check seems peculiar to me since the meaning of I2C_STAT_XRDY is
that new data is requested for transmission. Why is that indication that
the bus is not padconf'd for I2C?
