From d8fcd42089f109fffeb6cdcf1745013b91d7513e Mon Sep 17 00:00:00 2001 From: Angel Pons Date: Sun, 6 Dec 2020 23:55:08 +0100 Subject: mb/hp/280_g2: Add new mainboard MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This is a µATX mainboard with a LGA1151 socket and two DDR4 DIMM slots. There are two possible BOM configurations: Sid has no legacy devices, whereas Manny provides two serial ports, a parallel port, a PCI slot and PS/2 keyboard/mouse connectors. These boards also have different Super I/O models: Manny uses an ITE IT8625E, whereas legacy-free Sid comes with an ITE IT8656E instead. This coreboot port has been done using a Sid board, thus support for Manny-specific features is missing. Booting should still be possible, though: none of these legacy features is essential. The board has an unpopulated 6-pin header, wired to PCH UART 2. This can be used to retrieve coreboot logs. Working: - Both DIMM slots (Micron CT4G4DFS8213.8FA11, Hynix HMA851U6AFR6N-UH) - PCH SerialIO UART 2 to get coreboot logs - Rear USB ports - Realtek RTL8111 GbE NIC - Integrated graphics on DVI with libgfxinit - At least one SATA port - Flashing internally with flashrom - S3 suspend/resume - VBT - SeaBIOS 1.14 to boot Arch Linux (kernel linux-5.10.15.arch1-1) Untested: - Audio - VGA: DP2VGA chip uses DDI E, and libgfxinit doesn't support DDI E yet - Front USB headers - Non-Linux OSes - PCI slot - IT8625E peripherals: serial, parallel and PS/2 ports Change-Id: Iadf11c187307a24b15039a5a716737d9d74944e6 Signed-off-by: Angel Pons Reviewed-on: https://review.coreboot.org/c/coreboot/+/48386 Reviewed-by: Paul Menzel Reviewed-by: Michael Niewöhner Tested-by: build bot (Jenkins) --- src/mainboard/hp/280_g2/bootblock.c | 103 ++++++++++++++++++++++++++++++++++++ 1 file changed, 103 insertions(+) create mode 100644 src/mainboard/hp/280_g2/bootblock.c (limited to 'src/mainboard/hp/280_g2/bootblock.c') diff --git a/src/mainboard/hp/280_g2/bootblock.c b/src/mainboard/hp/280_g2/bootblock.c new file mode 100644 index 0000000000..f42c3f26f7 --- /dev/null +++ b/src/mainboard/hp/280_g2/bootblock.c @@ -0,0 +1,103 @@ +/* SPDX-License-Identifier: GPL-2.0-only */ + +#include +#include +#include +#include +#include +#include +#include + +static const struct pad_config gpio_table[] = { + PAD_CFG_NF(GPP_B14, DN_20K, PLTRST, NF1), /* SPKR */ + PAD_CFG_NF(GPP_C20, UP_20K, PLTRST, NF1), /* PCH_UART2_RXD */ + PAD_CFG_NF(GPP_C21, UP_20K, PLTRST, NF1), /* PCH_UART2_TXD */ + PAD_NC(GPP_C22, NONE), + PAD_CFG_GPI(GPP_C23, NONE, PLTRST), /* TODO: SIO PME# */ + PAD_CFG_NF(GPP_E8, NONE, DEEP, NF1), /* SATA_LED# */ + PAD_CFG_NF(GPP_E9, NONE, DEEP, NF1), /* USB_OC_LAN# */ + PAD_CFG_NF(GPP_E10, NONE, DEEP, NF1), /* USB3.0_OC_BACK# */ + PAD_CFG_NF(GPP_E11, NONE, DEEP, NF1), /* USB_OC_REAR2# */ + PAD_CFG_NF(GPP_E12, NONE, DEEP, NF1), /* USB_OC_FRONT1# */ + PAD_CFG_NF(GPP_F15, NONE, DEEP, NF1), /* USB_OC_FRONT2# */ + PAD_CFG_GPI(GPP_G1, NONE, PLTRST), /* LPT_DET# */ + PAD_CFG_GPO(GPP_G2, 0, PLTRST), /* AUD_AMP_ON# */ + PAD_CFG_GPO(GPP_G3, 0, PLTRST), /* W_DISABLE2# */ + PAD_CFG_GPI(GPP_G4, NONE, PLTRST), /* CLR_CMOS# */ + PAD_CFG_GPI(GPP_G5, NONE, PLTRST), /* CLR_PSWD# */ + PAD_CFG_GPI(GPP_G6, NONE, PLTRST), /* BOOT_BLOCK_EN# */ + PAD_CFG_GPI(GPP_G9, NONE, PLTRST), /* HOOD_SW_DET# */ + PAD_CFG_GPI(GPP_G12, NONE, PLTRST), /* FRONT_USB_DET1# */ + PAD_CFG_GPI(GPP_G13, NONE, PLTRST), /* FRONT_USB_DET2# */ + PAD_CFG_GPI(GPP_G14, NONE, PLTRST), /* FRONT_USB_DET3# */ + PAD_CFG_GPI(GPP_G16, NONE, PLTRST), /* F_AUDIO_DET# */ + PAD_CFG_GPI(GPP_G17, NONE, PLTRST), /* COMM_B_DET# */ + PAD_CFG_GPI_SCI(GPP_G21, NONE, DEEP, EDGE_SINGLE, INVERT), /* SPI_TPM_PIRQ# */ + PAD_CFG_GPI(GPP_H10, NONE, PLTRST), /* S_GPI_SKU0 */ + PAD_CFG_GPI(GPP_H15, NONE, PLTRST), /* BRD_REV0 */ + PAD_CFG_GPI(GPP_H16, NONE, PLTRST), /* BRD_REV1 */ + PAD_CFG_GPI(GPP_H17, NONE, PLTRST), /* BRD_REV2 */ + PAD_CFG_GPI(GPP_H18, NONE, PLTRST), /* S_GPI_SKU1 */ + PAD_CFG_NF(GPP_I2, NONE, PLTRST, NF1), /* DPD_HPD_R */ + PAD_CFG_NF(GPP_I3, NONE, PLTRST, NF1), /* DPE_HPD_R */ + PAD_CFG_NF(GPP_I9, NONE, PLTRST, NF1), /* DDPD_CTRLCLK */ + PAD_CFG_NF(GPP_I10, DN_20K, PLTRST, NF1), /* DDPD_CTRLDATA */ +}; + +static void mainboard_configure_super_io(void) +{ + const pnp_devfn_t dev = PNP_DEV(0x2e, 7); + + pnp_enter_conf_state(dev); + pnp_set_logical_device(dev); + + pnp_write_config(dev, 0x23, 0x59); + pnp_write_config(dev, 0x25, 0x10); + pnp_write_config(dev, 0x26, 0x04); + pnp_write_config(dev, 0x28, 0x08); + pnp_write_config(dev, 0x2a, 0x81); + pnp_write_config(dev, 0x71, 0x08); + pnp_write_config(dev, 0xc0, 0x00); + pnp_write_config(dev, 0xc1, 0x04); + pnp_write_config(dev, 0xc8, 0x00); + pnp_write_config(dev, 0xc9, 0x04); + pnp_write_config(dev, 0xcb, 0x08); + pnp_write_config(dev, 0xd5, 0x07); + pnp_write_config(dev, 0xf8, 0x12); + pnp_write_config(dev, 0xf9, 0x01); + + pnp_exit_conf_state(dev); +} + +void bootblock_mainboard_early_init(void) +{ + gpio_configure_pads(gpio_table, ARRAY_SIZE(gpio_table)); + + mainboard_configure_super_io(); +} + +void bootblock_mainboard_init(void) +{ + const gpio_t rev_gpios[] = { + GPP_H15, + GPP_H16, + GPP_H17, + }; + + const char *const rev_table[8] = { + [0] = "DB", + [1] = "Pre-SI", + [2] = "SI", + [3] = "PV", + [4] = "1.00 (SMVB)", + [5] = "1.10 (ECN1)", + [6] = "1.20 (ECN1)", + [7] = "1.30 (ECN1)", + }; + + const char *const brd_str = gpio_get(GPP_H10) ?
