2017-09-08soc/intel/common/block: Common ACPIShaunak Saha
This patch adds the common acpi code.ACPI code is very similar accross different intel chipsets.This patch is an effort to move those code in common place so that it can be shared accross different intel platforms instead of duplicating for each platform. We are removing the common acpi files in src/soc/intel/common. This removes the acpi.c file which was previously in src/soc/common/acpi. The config for common acpi is SOC_INTEL_COMMON_BLOCK_ACPI which can be defined in SOC's Kconfig file in order to use the common ACPI code. This patch also includes the changes in APL platform to use the common ACPI block. TEST= Tested the patch as below: 1.Builds and system boots up with the patch. 2.Check all the ACPI tables are present in /sys/firmware/acpi/tables 3.Check SCI's are properly working as we are modifying the function to override madt. 4.Extract acpi tables like DSDT,APIC, FACP, FACS and decompile the by iasl and compare with good known tables. 5.Execute the extracted tables in aciexec to check acpi methods are working properly.

Instead, make a `struct device` aware transfer() function the only interface function for I2C controller dri- vers to implement. To not force the slave device drivers to be implemented either above generic I2C or specialized SMBus operations, we support SMBus control- lers in the slave device interface too. We start with four simple slave functions: i2c_readb(), i2c_writeb(), i2c_readb_at() and i2c_writeb_at(). They are all compatible to respec- tive SMBus functions. But we keep aliases because it would be weird to force e.g. an I2C EEPROM driver to call smbus_read_byte().

2017-08-14i2c: Move to Linux like `struct i2c_msg`Nico Huber
Our current struct for I2C segments `i2c_seg` was close to being compa- tible to the Linux version `i2c_msg`, close to being compatible to SMBus and close to being readable (e.g. what was `chip` supposed to mean?) but turned out to be hard to fix. Instead of extending it in a backwards compatible way (and not touching current controller drivers), replace it with a Linux source compatible `struct i2c_msg` and patch all the drivers and users with Coccinelle. The new `struct i2c_msg` should ease porting drivers from Linux and help to write SMBus compatible controller drivers. Beside integer type changes, the field `read` is replaced with a generic field `flags` and `chip` is renamed to `slave`. Patched with Coccinelle using the clumsy spatch below and some manual changes: * Nested struct initializers and one field access skipped by Coccinelle. * Removed assumption in the code that I2C_M_RD is 1. * In `i2c.h`, changed all occurences of `chip` to `slave`. @@ @@ -struct i2c_seg +struct i2c_msg @@ identifier msg; expression e; @@ ( struct i2c_msg msg = { - .read = 0, + .flags = 0, }; | struct i2c_msg msg = { - .read = 1, + .flags = I2C_M_RD, }; | struct i2c_msg msg = { - .chip = e, + .slave = e, }; ) @@ struct i2c_msg msg; statement S1, S2; @@ ( -if (msg.read) +if (msg.flags & I2C_M_RD) S1 else S2 | -if (msg.read) +if (msg.flags & I2C_M_RD) S1 ) @@ struct i2c_msg *msg; statement S1, S2; @@ ( -if (msg->read) +if (msg->flags & I2C_M_RD) S1 else S2 | -if (msg->read) +if (msg->flags & I2C_M_RD) S1 ) @@ struct i2c_msg msg; expression e; @@ ( -msg.read = 0; +msg.flags = 0; | -msg.read = 1; +msg.flags = I2C_M_RD; | -msg.read = e; +msg.flags = e ?

2017-08-10soc/intel/common/uart: Add support for enabling UART debug controller on resumeFurquan Shaikh
It has been observed on a number of platforms (baytrail, kaby lake) that if serial console is not enabled in coreboot, but is enabled in kernel (v4.4), then on resume kernel hangs. In order to fix this, add support for enabling UART debug port controller on resume. In order to decide whether UART debug port controller should be enabled in ramstage, following things are checked in given order: 1. If coreboot has serial console enabled, there is no need to re-initialize the controller. 2. This special action is taken only for UART debug port controller. 3. If boot is not S3 resume, then initialization is skipped. 4. Callback into SoC to check if it wants to initialize the controller. If all the above conditions are met, then UART debug port controller is initialized and taken out of reset. BUG=b:64030366 TEST=Verified with the entire patchset series that: 1. If coreboot does not have serial console enabled, but Linux kernel has console enabled, then on resume, coreboot initializes UART debug port controller. 2. If coreboot and Linux do not have serial console enabled, then coreboot does not initialize UART debug port controller. 3. If coreboot has serial console enabled, there is no change in behavior.
