2017-11-15soc/intel: Enable ACPI DBG2 table generationDuncan Laurie
Enable the ACPI DBG2 table generation for Intel boards. This is a Microsoft defined ACPI extension that allows an OS to know what the debug port is on a system when it is not enabled by the firmware, so it does not show up in the coreboot tables and cannot be easily found by a payload. broadwell: Use byte access device, set up only when enabled since it relies on the port being put in byte access mode and using this serial port for debug was not standard in this generation. skylake: Enable for the configured debug port. Skylake uses intelblocks for UART but not ACPI. common: Enable for the configured debug port. This affects apollolake and cannonlake. Tested by compiling for apollolake/broadwell, tested by reading the DBG2 ACPI table on kabylake board and using IASL to dump: [000h 0000 4] Signature : "DBG2" [004h 0004 4] Table Length : 00000061 [008h 0008 1] Revision : 00 [009h 0009 1] Checksum : 3B [00Ah 0010 6] Oem ID : "CORE " [010h 0016 8] Oem Table ID : "COREBOOT" [018h 0024 4] Oem Revision : 00000000 [01Ch 0028 4] Asl Compiler ID : "CORE" [020h 0032 4] Asl Compiler Revision : 00000000 [024h 0036 4] Info Offset : 0000002C [028h 0040 4] Info Count : 00000001 [02Ch 0044 1] Revision : 00 [02Dh 0045 2] Length : 0035 [02Fh 0047 1] Register Count : 01 [030h 0048 2] Namepath Length : 000F [032h 0050 2] Namepath Offset : 0026 [034h 0052 2] OEM Data Length : 0000 [036h 0054 2] OEM Data Offset : 0000 [038h 0056 2] Port Type : 8000 [03Ah 0058 2] Port Subtype : 0000 [03Ch 0060 2] Reserved : 0000 [03Eh 0062 2] Base Address Offset : 0016 [040h 0064 2] Address Size Offset : 0022 [042h 0066 12] Base Address Register : [Generic Address Structure] [042h 0066 1] Space ID : 00 [SystemMemory] [043h 0067 1] Bit Width : 00 [044h 0068 1] Bit Offset : 00 [045h 0069 1] Encoded Access Width : 03 [DWord Access:32] [046h 0070 8] Address : 00000000FE034000 [04Eh 0078 4] Address Size : 00001000 [052h 0082 15] Namepath : "\_SB.PCI0.UAR2" Change-Id: If34a3d2252896e0b0f762136760ab981afc12a2f Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://review.coreboot.org/22453 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>

Disabling all GPEs was added recently in change 74145f76 (intel/common/pmc: Disable all GPEs during pmc_init) because keeping GPEs enabled in coreboot while enabling SMI could lead to side-effects as explained in the change.

2017-10-12intel/common/pmc: Disable all GPEs during pmc_initFurquan Shaikh
If GPEs are not cleared during pmc_init, it could result in issues if standard wake events are generated while coreboot is initializing. e.g. (Observed on soraka): 1. Suspend to S3 2. Lidclose 3. Lidopen 4. EC wakes up the host using WAKE# pin 5. On wakeup, pmc_init occurs which does not clear GPEs 6. MP init enables SMI 7. In order to add wake event to elog, coreboot sets wake mask on the EC, which causes the EC to assert WAKE#. 8. Since WAKE# is asserted, it results in an SMI#. However, EC does not de-assert WAKE# until host queries and clears the host event bit (which does not happen since coreboot is stuck in handling the SMIs). This is one of the issues that can occur when GPEs are unnecessarily enabled in coreboot. Before the move to PMC common library, SKL PMC driver set all GPEs to 0 and hence this issue did not occur. This change explicitly disables all GPEs during pmc init in order to avoid any side-effects. BUG=b:67712608 TEST=Verified that device resumes fine using lidclose/lidopen to suspend and resume.

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().

2017-08-17intel/common/block/fast_spi: Add config option to disable write statusDuncan Laurie
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. Add a configure option for this feature that will disable the opcode for Write Status commands unless CONFIG_CHROMEOS is enabled. 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.
