2017-08-22soc/intel/skylake: Lock sideband access in coreboot and not in FSPBarnali Sarkar
The Sideband Acces locking code is skipped from FSP by setting an FSP-S UPD called PchSbAccessUnlock. This locking is being done in coreboot during finalize.c. This is done because coreboot was failing to disable HECI1 device using Sideband interface during finalize.c if FSP already locks the Sideband access mechanism before that. So, as a solution, coreboot passes an UPD to skip the locking in FSP, and in finalize.c, after disabling HECI, it removes the Sideband access. BUG=b:63877089 BRANCH=none TEST=Build and boot poppy to check lspci not showing Intel ME controller in the PCI device list.

2017-08-21soc/intel/skylake: Fix SGX init sequencePratik Prajapati
Configure core PRMRR first on all the cores and then follow the SGX init sequence. Second microcode load would run the MCHECK. To pass MCHECK, PRMRR on all cores needs to be configured first. Hence, PRMRR configuration would be called from soc_core_init while MP init for each core and then from soc_init_cpus, BSP would call sgx_configure for each core (including for itself). This code flow satisfies the MCHECK passing pre-conditions; and apparently this patch fixes the behavior of calling configure_sgx() “again” for BSP. (So removed the TODO comment also).

2017-08-18Reinvent I2C opsNico Huber
Do not use the global platform_i2c_transfer() function that can only be implemented by a single driver. 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().

Chrome OS systems rely on the write status register to enable/disable flash write protection and disabling this opcode breaks the ability to enable or disable write protection with flashrom.

Tested to ensure that a default build without CONFIG_CHROMEOS has this option enabled while a build with CONFIG_CHROMEOS does not. Also ensured that when this option is disabled (for Chrome OS) then flashrom can be used with the --wp-enable and --wp-disable commands, depending on the state of the external write protect pin.

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.
