2017-09-11cpu/x86/mp_init: remove adjust_cpu_apic_entry()Aaron Durbin
The original purpose of adjust_cpu_apic_entry() was to set up an APIC map. That map was effectively only used for mapping *default* APIC id to CPU number in the SMM handler. The normal AP startup path didn't need this mapping because it was whoever won the race got the next cpu number. Instead of statically calculating (and wrong) just initialize the default APIC id map when the APs come online. Once the APs are online the SMM handler is loaded and the mapping is utilized.

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.

2017-09-02cpu/x86/smm: Fix explicit 'addr32' usage in clang buildsEdward O'Callaghan
The addr32 prefix is required by binutils, because even when given an explicit address which is greater than 64KiB, it will throw a warning about truncation, and stupidly emit the opcode with a 16-bit addressing mode and the wrong address. However, in the case of LLVM, this doesn't happen, and is happy to just use 32-bit addressing whenever it may require it. This means that LLVM never really needs an explicit addr32 prefix to use 32-bit addressing in 16-bit mode.

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 ?

2017-07-16assert: Add new dead_code() macro to assert dead code pathsJulius Werner
This patch adds a new kind of compile-time assertion based on Linux' compiletime_assert(). The difference to the existing use of _Static_assert() in coreboot (which should continue to be used where appropriate) is that this new assertion only hits if the call to it is not optimized out at compile time. It is therefore ideal to assert that certain code paths are not included in the image if a certain Kconfig option is (not) set. For example, assert(!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE)); can be rewritten as if (!IS_ENABLED(CONFIG_THAT_MAKES_THIS_INAPPROPRIATE)) dead_code("This code shouldn't be built for config X"); to turn it into a compile-time check.

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

2017-06-04console/flashsconsole: Add spi flash console for debuggingYouness Alaoui
If CONSOLE_SPI_FLASH config is enabled, we write the cbmem messages to the 'CONSOLE' area in FMAP which allows us to grab the log when we read the flash. This is useful when you don't have usb debugging, and UART lines are hard to find. Since a failure to boot would require a hardware flasher anyways, we can get the log at the same time. This feature should only be used when no alternative is found and only when we can't boot the system, because excessive writes to the flash is not recommended. This has been tested on purism/librem13 v2 and librem 15 v3 which run Intel Skylake hardware. It has not been tested on other archs or with a driver other than the fast_spi.

For some reason the "interface" for adding framebuffer information is sitting in src/include/vbe.h while also guarding the call to fill_lb_framebuffer() with vbe_mode_info_valid() along with some macro if CONFIG_* for good measure. Move the fill_lb_framebuffer() declaration to coreboot_tables.h and provide a comment about how it should be used. Also, now that there's no need for the notion of a global vbe_mode_info_valid() remove it from the conditional call path of fill_lb_framebuffer().

AGESA and binaryPI boards have no easy way to determine correct cbmem_top() location early enough when GFXUMA is enabled, so they will use these functions with EARLY_CBMEM_INIT as well. At the end of AmdInitPost() the decisions of UMA base and size have not been written to hardware yet. The decisions are stored inside AGESA heap object we cannot locate from coreboot proper until after AmdInitEnv().

DEVTREE_EARLY which is true when !ENV_RAMSTAGE 2. DEVTREE_CONST as a replacment for ROMSTAGE_CONST The ROMSTAGE_CONST attribute is used in the source code to mark the devicetree data structures as const in early stages even though it's not just romstage. Therefore, rename the attribute to DEVTREE_CONST as that's the actual usage. The only place where the usage was not devicetree related is console_loglevel, but the same name was used for consistency. Any stage that is not ramstage has the const C attribute applied when DEVTREE_CONST is used.

2017-04-25drivers/storage: Add SD/MMC/eMMC driver based upon depthchargeLee Leahy
The SD/MMC support is broken into several pieces. There are three main data structures: * sdhci_ctrlr - This is SDHCI controller specific and defined in include/device/sdhci.h * sd_mmc_ctrlr - This contains generic controller management data and defined in include/device/sd_mmc_ctrlr.h * storage_media - This contains the flash storage device management data and is defined in include/device/storage.h The SD/MMC driver consists of several components: * SDHCI controller code * bouncebuf.c * bouncebuf.h * pci_sdhci.c * sdhci.c * sdhci.h * sdhci_adma.c * sdhci_display.c * Flash storage device support * mmc.c * mmc.h * sd.c * sd_mmc.c * sd_mmc.h * storage.c * storage.h * storage_erase.c * storage_write.c Kconfig values enable various portions of the controller and storage drivers to be built to reduce the overall size of what is included in the final image. Full read/write/erase operations are provided for those platforms which want to take advantage. It is also possible to build the driver to perform initialization only. By default, this driver is not included in any platform, platforms must specifically select DRIVERS_STORAGE to add the SD/MMC support. After this patch is reviewed and merged, there are some additional patches: * Common CAR storage area - Use a predefined region of CAR to pass data structures between bootblock through to romstage. This allows early stages to preform the SD/MMC device initialization and later stages to use the SD/MMC device without further initialization. The example code initializes the SD/MMC device in bootblock and uses the SD/MMC device in romstage without further initialization. * CBMEM ID - Add a CBMEM ID value for the data structures so that they may be passed from romstage to ramstage and eventually the payload. The example uses the SD/MMC device in ramstage without further initialization. * Move the SD/MMC driver into commonlib * Have libpayload build the SD/MMC driver from commonlib. The intent is to pass the controller state to libpayload so that the SD/MMC device can be used without further initialization. * On some platforms, have depthcharge use the commonlib SD/MMC driver History: Copy the SD/MMC driver from depthcharge revision eb583fa8 into coreboot and make the following changes: * Removed #include "config.h" from mmc.c, allow the lint tests to pass. * Move include files from drivers/storage into include/device. * Rename mmc.h to storage.h. * Add the Kconfig and Makefile and make edits to get the code to build. * Add support to initialize a PCI controller. * Fix formatting issues detected by checkpatch. * Fix data flow issues detected by checkpatch. * Add the missing voltage (MMC_VDD_35_36) into the voltage mask. * Rename the macros mmc_debug, mmc_trace and mmc_error to sd_mmc_*. * Replace printf with sd_mmc_error. * Add sdhc_debug, sdhc_trace and sd_error macros. * Add Kconfig values to enable storage device debugging and tracing. * Add tracing and debug support to the SDHCI driver. * Allow SOC to override more controller features. * Split out ADMA support. * Move 1V8 support into SOC routine. * Move HS400 support into SOC routine. * Rework clock handling. * Change all controller references to use ctrlr. * Update the voltage handling. * Update modes of operation. * Move DMA fields into MmcCtrlr. * Update bus width support. * Change MMC_TIMING_* to BUS_TIMING_*. * Rename MMC_MODE_ to DRVR_CAP. * Move quirks into ctrlr->caps. * Associate removeable with the controller. * Statically allocate MmcMedia. * Replace the SdhciHost structure with the MmcCtrlr structure. * Split the code to support other SD/MMC controllers. * Split out erase and write support. * Update the code to be more consistent with the coreboot coding style. * Only expose calling APIs. * Divide up mmc.c into 4 modules: MMC, SD, storage card, common code. * Update debug and error messages. * Add partition support. * Display clock frequencies once in MHz. * Remove mmc_send_cmd, use ctrlr->send_cmd instead. * Handle error from sd_send_op_cond. * Allow mainboard to control delays around CMD 0. * Support command logging. * Mainboard may set delay after SD/MMC command. * Display serial number with sd_mmc_trace. * Remove cmd set parameter from mmc_switch. * Display errors for timeout and comm errors. * Add LED support. * Move 64bit DMA flag into ctrlr->caps. * Rework PIO transfer routine. * Add HS200 bus tuning. * Add support for HS400. * Use same format for HS400, HS200 and HS52. * Reduce storage_media structure size * Add routine to update code pointers * Add display of storage setup * Display controller setup TEST=Build and run on Reef and Galileo Gen2 Change-Id: I9b5f9db1e27833e4ce4a97ad4f5ef3a46f64f2a2 Signed-off-by: Lee Leahy <leroy.p.leahy@intel.com> Reviewed-on: https://review.coreboot.org/19208 Tested-by: build bot (Jenkins) Reviewed-by: Stefan Reinauer <stefan.reinauer@coreboot.org>

2017-03-28vboot: Disallow separate verstage after romstage, try to clarify logicJulius Werner
No board has ever tried to combine CONFIG_SEPARATE_VERSTAGE with CONFIG_VBOOT_STARTS_IN_ROMSTAGE. There are probably many reasons why this wouldn't work (e.g. x86 CAR migration logic currently always assumes verstage code to run pre-migration). It would also not really make sense: the reason we use separate verstages is to decrease bootblock size (mitigating the boot speed cost of slow boot ROM SPI drivers) and to allow the SRAM-saving RETURN_FROM_VERSTAGE trick, neither of which would apply to the after-romstage case. It is better to just forbid that case explicitly and give programmers more guarantees about what the verstage is (e.g. now the assumption that it runs pre-RAM is always valid). Since Kconfig dependencies aren't always guaranteed in the face of 'select' statements, also add some explicit compile-time assertions to the vboot code. We can simplify some of the loader logic which now no longer needs to provide for the forbidden case. In addition, also try to make some of the loader logic more readable by writing it in a more functional style that allows us to put more assertions about which cases should be unreachable in there, which will hopefully make it more robust and fail-fast with future changes (e.g. addition of new stages).

2017-03-23cr50: add unmarshaling of vendor commands and process 'enable_update'Vadim Bendebury
The upcoming Cr50 firmware changes will require the AP to enable the previously downloaded Cr50 firmware update(s). A new vendor command (TPM2_CR50_SUB_CMD_TURN_UPDATE_ON) is used for that. The command accepts one parameter - a timeout value in range of 0 to 1000 ms. When processing the command the Cr50 checks if the alternative RO or RW image(s) need to be enabled, and if so - enables them and returns to the host the number of enabled headers. If the vendor command requested a non-zero timeout, the Cr50 starts a timer to trigger system reboot after the requested timeout expires. The host acts on the number of enabled headers - if the number is nonzero, the host prepares the device to be reset and waits for the Cr50 to reboot the device after timeout expires. This patch also adds more formal vendor command marshaling/unmarshaling to make future additions easier.
