u-boot/doc/README.s5pc1xx

5 This README is about U-Boot support for SAMSUNG's ARM Cortex-A8 based S5PC1xx
6 family of SoCs (S5PC100 [1] and S5PC110).
15 While ARM Cortex-A8 support ARM v7 instruction set (-march=armv7a) we compile
16 with -march=armv5 to allow more compilers to work. For U-Boot code this has
47 	/* GPA[0] pin set to irq */
48 	gpio_cfg_pin(&gpio->gpio_a, 0, GPIO_IRQ);
50 	/* GPA[0] pin set to input */
51 	gpio_direction_input(&gpio->gpio_a, 0);
53 	/* GPA[0] pin set to output/high */
54 	gpio_direction_output(&gpio->gpio_a, 0, 1);
56 	/* GPA[0] value set to low */
57 	gpio_set_value(&gpio->gpio_a, 0, 0);
59 	/* get GPA[0] value */
60 	value = gpio_get_value(&gpio->gpio_a, 0);
