From 166b55ced1ee114c6ae13a26d8eb14370da3e039 Mon Sep 17 00:00:00 2001 From: Felix Held Date: Mon, 7 Oct 2019 18:10:30 +0200 Subject: superio/hwm5_conf: factor out HWM access from ITE env_ctrl Nuvoton and Winbond use the same off-by-5 indirect address space to access their hardware monitor/environment controller in the SIO chip, so move this to a common location and replace the inb/outb calls with the corresponding inline functions from device/pnp.h Change-Id: I20606313d0cc9cf74be7dca30bc4550059125fe1 Signed-off-by: Felix Held Reviewed-on: https://review.coreboot.org/c/coreboot/+/35858 Tested-by: build bot (Jenkins) Reviewed-by: HAOUAS Elyes --- src/superio/ite/common/env_ctrl.c | 122 ++++++++++++++++---------------------- 1 file changed, 51 insertions(+), 71 deletions(-) (limited to 'src/superio/ite') diff --git a/src/superio/ite/common/env_ctrl.c b/src/superio/ite/common/env_ctrl.c index 1b93036845..2f2942be7b 100644 --- a/src/superio/ite/common/env_ctrl.c +++ b/src/superio/ite/common/env_ctrl.c @@ -21,22 +21,11 @@ #include #include #include +#include #include "env_ctrl.h" #include "env_ctrl_chip.h" -static inline u8 ite_ec_read(const u16 base, const u8 addr) -{ - outb(addr, base + 5); - return inb(base + 6); -} - -static inline void ite_ec_write(const u16 base, const u8 addr, const u8 value) -{ - outb(addr, base + 5); - outb(value, base + 6); -} - static void extemp_force_idle_status(const u16 base) { u8 reg; @@ -44,7 +33,7 @@ static void extemp_force_idle_status(const u16 base) /* Wait up to 10ms for non-busy state. */ while (retries > 0) { - reg = ite_ec_read(base, ITE_EC_EXTEMP_STATUS); + reg = pnp_read_hwm5_index(base, ITE_EC_EXTEMP_STATUS); if ((reg & ITE_EC_EXTEMP_STATUS_HOST_BUSY) == 0x0) break; @@ -59,9 +48,8 @@ static void extemp_force_idle_status(const u16 base) * SIO is busy due to unfinished peci transaction. * Re-configure Register 0x8E to terminate processes. */ - ite_ec_write(base, ITE_EC_EXTEMP_CONTROL, - ITE_EC_EXTEMP_CTRL_AUTO_4HZ | - ITE_EC_EXTEMP_CTRL_AUTO_START); + pnp_write_hwm5_index(base, ITE_EC_EXTEMP_CONTROL, + ITE_EC_EXTEMP_CTRL_AUTO_4HZ | ITE_EC_EXTEMP_CTRL_AUTO_START); } } @@ -71,22 +59,16 @@ static void extemp_force_idle_status(const u16 base) static void enable_peci(const u16 base) { /* Enable PECI interface */ - ite_ec_write(base, ITE_EC_INTERFACE_SELECT, - ITE_EC_INTERFACE_SEL_PECI | - ITE_EC_INTERFACE_SPEED_TOLERANCE); + pnp_write_hwm5_index(base, ITE_EC_INTERFACE_SELECT, + ITE_EC_INTERFACE_SEL_PECI | ITE_EC_INTERFACE_SPEED_TOLERANCE); /* Setup External Temperature using PECI GetTemp */ - ite_ec_write(base, ITE_EC_EXTEMP_ADDRESS, - PECI_CLIENT_ADDRESS); - ite_ec_write(base, ITE_EC_EXTEMP_COMMAND, - PECI_GETTEMP_COMMAND); - ite_ec_write(base, ITE_EC_EXTEMP_WRITE_LENGTH, - PECI_GETTEMP_WRITE_LENGTH); - ite_ec_write(base, ITE_EC_EXTEMP_READ_LENGTH, - PECI_GETTEMP_READ_LENGTH); - ite_ec_write(base, ITE_EC_EXTEMP_CONTROL, - ITE_EC_EXTEMP_CTRL_AUTO_4HZ | - ITE_EC_EXTEMP_CTRL_AUTO_START); + pnp_write_hwm5_index(base, ITE_EC_EXTEMP_ADDRESS, PECI_CLIENT_ADDRESS); + pnp_write_hwm5_index(base, ITE_EC_EXTEMP_COMMAND, PECI_GETTEMP_COMMAND); + pnp_write_hwm5_index(base, ITE_EC_EXTEMP_WRITE_LENGTH, PECI_GETTEMP_WRITE_LENGTH); + pnp_write_hwm5_index(base, ITE_EC_EXTEMP_READ_LENGTH, PECI_GETTEMP_READ_LENGTH); + pnp_write_hwm5_index(base, ITE_EC_EXTEMP_CONTROL, + ITE_EC_EXTEMP_CTRL_AUTO_4HZ | ITE_EC_EXTEMP_CTRL_AUTO_START); } /* @@ -98,7 +80,7 @@ static void enable_tmpin(const u16 base, const u8 tmpin, { u8 reg; - reg = ite_ec_read(base, ITE_EC_ADC_TEMP_CHANNEL_ENABLE); + reg = pnp_read_hwm5_index(base, ITE_EC_ADC_TEMP_CHANNEL_ENABLE); switch (conf->mode) { case THERMAL_PECI: @@ -122,26 +104,25 @@ static void enable_tmpin(const u16 base, const u8 tmpin, return; } - ite_ec_write(base, ITE_EC_ADC_TEMP_CHANNEL_ENABLE, reg); + pnp_write_hwm5_index(base, ITE_EC_ADC_TEMP_CHANNEL_ENABLE, reg); /* Set temperature offsets */ if (conf->mode != THERMAL_RESISTOR) { - reg = ite_ec_read(base, ITE_EC_BEEP_ENABLE); + reg = pnp_read_hwm5_index(base, ITE_EC_BEEP_ENABLE); reg |= ITE_EC_TEMP_ADJUST_WRITE_ENABLE; - ite_ec_write(base, ITE_EC_BEEP_ENABLE, reg); - ite_ec_write(base, ITE_EC_TEMP_ADJUST[tmpin-1], conf->offset); + pnp_write_hwm5_index(base, ITE_EC_BEEP_ENABLE, reg); + pnp_write_hwm5_index(base, ITE_EC_TEMP_ADJUST[tmpin-1], conf->offset); } /* Set temperature limits */ u8 max = conf->max; - ite_ec_write(base, ITE_EC_HIGH_TEMP_LIMIT(tmpin), - max ?
