Change in ...coreboot[master]: vendorcode/google/chromeos: Add option for using ACPI GPIO pin

by Duncan Laurie (Code Review)

Duncan Laurie has uploaded this change for review. ( https://review.coreboot.org/c/coreboot/+/31080 Change subject: vendorcode/google/chromeos: Add option for using ACPI GPIO pin ...................................................................... vendorcode/google/chromeos: Add option for using ACPI GPIO pin This new option will have the generated Chrome OS ACPI GPIO table provide the ACPI GPIO pin number instead of the raw GPIO number. This is necessary if the OS uses a different numbering for GPIOs that are reported in ACPI than the actual underlying GPIO number. For example, if the SOC OS driver declares more pins in an ACPI GPIO bank than there are actual pins in the hardware it will have gaps in the number space. This is a reworked version of 6217e9beff16d805ca833e79a2931bcdb3d02a44 which uses a new option instead of just relying on GENERIC_GPIO_LIB.

Change in ...coreboot[master]: sb/intel/common: Rename i2c_block_read() to i2c_eeprom_read()

by Kyösti Mälkki (Code Review)

Kyösti Mälkki has uploaded this change for review.

Followups will add a symmetrical pair of commands i2c_block_read() and i2c_block_write() that operate via I2C_EN bit and have a 32 byte size restriction on block transfers. For some hardware revision these block commands are available, while 'I2C Read' was not.

Change in ...coreboot[master]: cbmem: use aligned_memcpy for reading cbmem address information

by Aaron Durbin (Code Review)
