inteltool: Add option to show differences in GPIO setup
This adds an option -G, --gpio-diffs to inteltool, which shows GPIO settings that differ from platform defaults. For differing registers, the current, the default, and an xor of the default and the current value is printed. A follow-up commit will add defaults for the Cougar/Panther Point platform controller hubs. If you specify both, -g and -G on the command line, all GPIO registers will be printed interleaved with the diff. Here's a preview: $ ./inteltool -G CPU: Processor Type: 0, Family 6, Model 3a, Stepping 9 Northbridge: 8086:0150 (unknown) Southbridge: 8086:1e4a (H77) ========== GPIO DIFFS =========== GPIOBASE = 0x0500 (IO) gpiobase+0x0000: 0xb96ba1fb (GPIO_USE_SEL) gpiobase+0x0000: 0xb96ba1ff (GPIO_USE_SEL) DEFAULT gpiobase+0x0000: 0x00000004 (GPIO_USE_SEL) DIFF gpiobase+0x0004: 0x06ff6efb (GP_IO_SEL) gpiobase+0x0004: 0xeeff6eff (GP_IO_SEL) DEFAULT gpiobase+0x0004: 0xe8000004 (GP_IO_SEL) DIFF gpiobase+0x000c: 0xe1f17f7e (GP_LVL) gpiobase+0x000c: 0x02fe0100 (GP_LVL) DEFAULT gpiobase+0x000c: 0xe30f7e7e (GP_LVL) DIFF gpiobase+0x002c: 0x00002000 (GPI_INV) gpiobase+0x002c: 0x00000000 (GPI_INV) DEFAULT gpiobase+0x002c: 0x00002000 (GPI_INV) DIFF gpiobase+0x0030: 0x0aff70ff (GPIO_USE_SEL2) gpiobase+0x0030: 0x020300ff (GPIO_USE_SEL2) DEFAULT gpiobase+0x0030: 0x08fc7000 (GPIO_USE_SEL2) DIFF gpiobase+0x0034: 0x15038ff2 (GP_IO_SEL2) gpiobase+0x0034: 0x1f57fff4 (GP_IO_SEL2) DEFAULT gpiobase+0x0034: 0x0a547006 (GP_IO_SEL2) DIFF gpiobase+0x0038: 0xb65e7f4f (GP_LVL2) gpiobase+0x0038: 0xa4aa0007 (GP_LVL2) DEFAULT gpiobase+0x0038: 0x12f47f48 (GP_LVL2) DIFF gpiobase+0x0040: 0x000001f3 (GPIO_USE_SEL3) gpiobase+0x0040: 0x00000130 (GPIO_USE_SEL3) DEFAULT gpiobase+0x0040: 0x000000c3 (GPIO_USE_SEL3) DIFF gpiobase+0x0044: 0x00000ef3 (GPIO_SEL3) gpiobase+0x0044: 0x00000ff0 (GPIO_SEL3) DEFAULT gpiobase+0x0044: 0x00000103 (GPIO_SEL3) DIFF gpiobase+0x0048: 0x00000dfc (GPIO_LVL3) gpiobase+0x0048: 0x000000c0 (GPIO_LVL3) DEFAULT gpiobase+0x0048: 0x00000d3c (GPIO_LVL3) DIFF gpiobase+0x0060: 0x00000000 (GP_RST_SEL1) gpiobase+0x0060: 0x01000000 (GP_RST_SEL1) DEFAULT gpiobase+0x0060: 0x01000000 (GP_RST_SEL1) DIFF $ ./inteltool -gG CPU: Processor Type: 0, Family 6, Model 3a, Stepping 9 Northbridge: 8086:0150 (unknown) Southbridge: 8086:1e4a (H77) ============= GPIOS ============= GPIOBASE = 0x0500 (IO) gpiobase+0x0000: 0xb96ba1fb (GPIO_USE_SEL) gpiobase+0x0000: 0xb96ba1ff (GPIO_USE_SEL) DEFAULT gpiobase+0x0000: 0x00000004 (GPIO_USE_SEL) DIFF gpiobase+0x0004: 0x06ff6efb (GP_IO_SEL) gpiobase+0x0004: 0xeeff6eff (GP_IO_SEL) DEFAULT gpiobase+0x0004: 0xe8000004 (GP_IO_SEL) DIFF gpiobase+0x0008: 0x00000000 (RESERVED) gpiobase+0x000c: 0xe1f17f7e (GP_LVL) gpiobase+0x000c: 0x02fe0100 (GP_LVL) DEFAULT gpiobase+0x000c: 0xe30f7e7e (GP_LVL) DIFF gpiobase+0x0010: 0x00000000 (RESERVED) gpiobase+0x0014: 0x00000000 (RESERVED) gpiobase+0x0018: 0x00040000 (GPO_BLINK) gpiobase+0x001c: 0x00000000 (GP_SER_BLINK) gpiobase+0x0020: 0x00080000 (GP_SB_CMDSTS) gpiobase+0x0024: 0x00000000 (GP_SB_DATA) gpiobase+0x0028: 0x0000 (GPI_NMI_EN) gpiobase+0x002a: 0x0000 (GPI_NMI_STS) gpiobase+0x002c: 0x00002000 (GPI_INV) gpiobase+0x002c: 0x00000000 (GPI_INV) DEFAULT gpiobase+0x002c: 0x00002000 (GPI_INV) DIFF gpiobase+0x0030: 0x0aff70ff (GPIO_USE_SEL2) gpiobase+0x0030: 0x020300ff (GPIO_USE_SEL2) DEFAULT gpiobase+0x0030: 0x08fc7000 (GPIO_USE_SEL2) DIFF gpiobase+0x0034: 0x15038ff2 (GP_IO_SEL2) gpiobase+0x0034: 0x1f57fff4 (GP_IO_SEL2) DEFAULT gpiobase+0x0034: 0x0a547006 (GP_IO_SEL2) DIFF gpiobase+0x0038: 0xb65e7f4f (GP_LVL2) gpiobase+0x0038: 0xa4aa0007 (GP_LVL2) DEFAULT gpiobase+0x0038: 0x12f47f48 (GP_LVL2) DIFF gpiobase+0x003c: 0x00000000 (RESERVED) gpiobase+0x0040: 0x000001f3 (GPIO_USE_SEL3) gpiobase+0x0040: 0x00000130 (GPIO_USE_SEL3) DEFAULT gpiobase+0x0040: 0x000000c3 (GPIO_USE_SEL3) DIFF gpiobase+0x0044: 0x00000ef3 (GPIO_SEL3) gpiobase+0x0044: 0x00000ff0 (GPIO_SEL3) DEFAULT gpiobase+0x0044: 0x00000103 (GPIO_SEL3) DIFF gpiobase+0x0048: 0x00000dfc (GPIO_LVL3) gpiobase+0x0048: 0x000000c0 (GPIO_LVL3) DEFAULT gpiobase+0x0048: 0x00000d3c (GPIO_LVL3) DIFF gpiobase+0x004c: 0x00000000 (RESERVED) gpiobase+0x0050: 0x00000000 (RESERVED) gpiobase+0x0054: 0x00000000 (RESERVED) gpiobase+0x0058: 0x00000000 (RESERVED) gpiobase+0x005c: 0x00000000 (RESERVED) gpiobase+0x0060: 0x00000000 (GP_RST_SEL1) gpiobase+0x0060: 0x01000000 (GP_RST_SEL1) DEFAULT gpiobase+0x0060: 0x01000000 (GP_RST_SEL1) DIFF gpiobase+0x0064: 0x00000000 (GP_RST_SEL2) gpiobase+0x0068: 0x00000000 (GP_RST_SEL3) gpiobase+0x006c: 0x00000000 (RESERVED) gpiobase+0x0070: 0x00000000 (RESERVED) gpiobase+0x0074: 0x00000000 (RESERVED) gpiobase+0x0078: 0x00000000 (RESERVED) gpiobase+0x007c: 0x00000000 (RESERVED) Change-Id: Ic77474c4bc0871e95103ddecd9f6a9406c8f016d Signed-off-by: Nico Huber <nico.h@gmx.de> Reviewed-on: http://review.coreboot.org/3000 Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>
