2008-06-23	ppc4xx: Fix problem in gpio_config()	Stefan Roese
	As pointed out by Guennadi Liakhovetski (thanks), pin2 is already shifted left by one. So the additional shift is bogus. Signed-off-by: Stefan Roese <sr@denx.de>
2008-01-04	ppc4xx: Add functionality to GPIO support	Lawrence R. Johnson
	This patch makes two additions to GPIO support: First, it adds function gpio_read_in_bit() to read the a bit from the GPIO Input Register (GPIOx_IR) in the same way that function gpio_read_out_bit() reads a bit from the GPIO Output Register (GPIOx_OR). Second, it modifies function gpio_set_chip_configuration() to provide an additional option for configuring the GPIO from the "CFG_4xx_GPIO_TABLE". According to the 440EPx User's Manual, when an alternate output is used, the three-state control is configured in one of two ways, depending on the particular output. The first option is to select the corresponding alternate three-state control in the GPIOx_TRSH/L registers. The second option is to select the GPIO Three-State Control Register (GPIOx_TCR) in the GPIOx_TRSH/L registers, and set the corresponding bit in the GPIOx_TCR register to enable the output. For example, the Manual specifies configuring the GPIO00 Alternate 1 Signal (PreAddr07) to use the alternate three-state control (first option), and specifies configuring the GPIO32 Alternate 1 Signal (USB2OM0) with the output enabled in the GPIOx_TCR register (second option). Currently, gpio_set_chip_configuration() configures all alternate signal outputs to use the first option. This patch allow the second option to be selected by setting the "out_val" element in the table entry to "GPIO_OUT_1". The first option is used when the "out_val" element is set to "GPIO_OUT_0". Because "out_val" is not currently used when an alternate signal is selected, and because all current GPIO tables set "out_val" to "GPIO_OUT_0" for all alternate signals, this patch should not change any existing configurations.
