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.

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().

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.

2017-07-28soc/intel/skylake: Remove incorrect ME PG-status printBarnali Sarkar
As per discussion with CSME team, ME is NOT using PCI Config Space register HFSTS2 Bit 10 to update ME power-gated status. ME goes to CM0-PG state after ME device becomes idle after Bit 2 of MMIO register offset 0x800 (D0i3 Control - HECI1_D0I3C) is being set. And to retrieve the PG status of ME, one should read from the PWRMBASE+offset 0x590 (which should give the value 0xF9) and PWRMBASE+offset 0x594 (which should give the value 0xFF). But, also it needs some time for the ME FW to go to idle state and reflect these values in PWRMBASE registers after D0i3 bit is being set. This does not happen instantly. So, in coreboot, if we read the ME PG state in finalize.c, which happens just after FSP Notify phase, where actually ME D0i3 bit is set, we do not read the correct PG state values (i.e, 0xF9 and 0xFF). But, once it boots to Kernel, if we read those same registers through iotool mmio_read32 command, we get correct values. So, removing the ME PG state prints from coreboot, since it is actually showing wrong information, although ME Power Gating is successful.

Remove the unused support code from the old multi-device hudson SD controller. The binaryPI blob contains the correct steps for setting up SD and the public BKDG doesn't completely document the controller. The sd.c file was using device IDs not associated with the Stoney Ridge APU. The hudson_enable() code removed was also looking for incorrect device IDs and the PM_MANUAL_RESET register doesn't behave as the source indicates. The SD default settings may be overridden. Future improvements may include a few Kconfig options and a weak call to the mainboard for overriding additional defaults.

Add dedicated CAR setup and teardown functions and Kconfig options to force their inclusion into the build. The .S files are mostly duplicated code from the old cache_as_ram.inc file. The .S files use global proc names in anticipation for use with the Kconfig symbols C_ENVIRONMENT_BOOTBLOCK and POSTCAR_STAGE. Move the mainboard romstage functionality into the soc directory and change the function name to be compatible with the call from assembly_entry.S. Drop the BIST check like other devices. Move InitReset and InitEarly to bootblock. These AGESA entry points set some default settings, and release/recapture the AP cores. There are currently some early dependencies on InitReset. Future work should include: * Pull the necessary functionality from InitReset into bootblock * Move InitReset and InitEarly to car_stage_entry() and out of bootblock - Add a mechanism for the BSP to give the APs an address to call and skip most of bootblock and verstage (when available) (1) - Reunify BiosCallOuts.c and OemCustomize.c (1) During the InitReset call, the BSP enables the APs by setting core enable bits in F18F0x1DC and APs begin fetching/executing from the reset vector. The BSP waits for all APs to also reach InitReset, where they enter an endless loop. The BSP sends a command to them to execute a HLT instruction and the BSP eventually returns from InitReset. The goal would be to preserve this process but prevent APs from rerunning early code.
