2019-08-08arch/x86: Change smm_subregion() prototypeKyösti Mälkki
Do this to avoid some amount of explicit typecasting that would be required otherwise.

2019-08-08drivers/ipmi: Add option to wait for BMCPatrick Rudolph
The BMC on Supermicro X11SSH takes 34 seconds to start the IPMI KCS, but the default timeout of the IPMI KCS code is just 100 msec. Add a configurable timeout option to wait for the BMC to become ready. As it only should boot very long after power on reset, it's not a problem on reset or warm boot. Tested on Supermicro X11SSH. The IPMI driver doesn't fail with a time-out any more.

2019-08-06security/vboot: Add Support for Intel PTTChristian Walter
Add support for Intel PTT. For supporting Intel PTT we need to disable read and write access to the TPM NVRAM during the bootblock. TPM NVRAM will only be available once the DRAM is initialized. To circumvent this, we mock secdata if HAVE_INTEL_PTT is set. The underlying problem is, that the iTPM only supports a stripped down instruction set while the Intel ME is not fully booted up. Details can be found in Intel document number 571993 - Paragraph 2.10.

2019-08-04drivers/fsp1_1/raminit: fix use of mrc_hobMatt DeVillier
Commit 509f469 [drivers/fsp1_1/raminit.c: Always check FSP HOBs] inadvertently made use of the mrc_hob conditional on CONFIG_DISPLAY_HOBS, when there is no relation between the two, leading to MRC cache data being corrupted. On some devices this caused RAM training to be redone, on others it resulted in a bricked device. Fix this by removing the condition on CONFIG_DISPLAY_HOBS. Test: boot google/{cyan,edgar}, observe third boot and onward do not brick device, properly use mrc_hob via cbmem console and timestamps.

2019-06-10spi_flash: Add Dual SPI supportJulius Werner
This patch adds support to read SPI flash in Dual SPI mode, where both MISO and MOSI lines are used for output mode (specifically Fast Read Dual Output (0x3b) where the command is still sent normally, not Fast Read Dual I/O (0xbb) whose additional benefit should be extremely marginal for our use cases but which would be more complicated to implement). This feature needs to be supported by both the flash chip and the controller, so we add a new dual_spi flag (and a new flags field to hold it) to the spi_flash structure and a new optional xfer_dual() function pointer to the spi_ctrlr structure. When both are provided, Dual SPI mode is used automatically, otherwise things work as before. This patch only adds the dual_spi flag exemplary to all Winbond and Gigadevice chips, other vendors need to be added as needed.

2019-06-10spi_flash: Make .read() callback optionalJulius Werner
All SPI flash chip drivers currently in coreboot use the generic read functions (spi_flash_cmd_read_fast()/_slow()) as their read callback. The only use case for specialized read callbacks we have left is with specialized flash controllers like Intel fast_spi (which sort of impersonate the flash chip driver by implementing their own probe function). This patch unifies the behavior for all normal flash drivers by making the read callback optional and letting them all fall back to a default read implementation that handles normal fast/slow reading. Most of the drivers used to install the respective callback after checking CONFIG_SPI_FLASH_NO_FAST_READ, but some hardcoded either slow or fast writes. I have found no indications for why this is and spot-checked datasheets for affected vendors to make sure they all support both commands, so I assume this is just some old inaccuracy rather than important differences that need preserving. (Please yell if you disagree.) Also take the opportunity to refactor some of the common spi_flash.c code a bit because I felt there are too many nested functions that don't really do enough on their own, and centralizing stuff a bit should make it easier to follow the code flow. (Some of this is in preparation for the next patch.)

This patch changes the Gigadevice SPI flash driver to adopt the same structure packing improvements for the hardcoded parameters of individual chips that was implemented for Winbond last year. This cuts the size of the hardcoded info nearly in half and should save us a few hundred bytes in every stage.

2019-06-10cbfs_spi: Enable speed logging by default for BIOS_DEBUGJulius Werner
The SPI transfer speed logging in cbfs_spi is super useful, doesn't get in the way (just adding one line per stage, essentially) and should have no notable overhead. Let's enable it by default for the BIOS_DEBUG log level rather than having to recompile to get it. Also fix an issue with building this code on MIPS due to lack of 64-bit division primitives. (This means MIPS and arm32 board may display incorrect results when reading more than 4MB in a single transfer, which sounds very unlikely.)

2019-06-04soc/intel/braswell: Use common cpu/intel/car codeArthur Heymans
The code in cpu/intel/car/romstage.c Does most of the things like setting up timestamps, stack guards, entering postcar. A functional difference is that the FSP header is searched for twice instead of passed from the CAR entry to the C code. When using C_ENVIRONMENT_BOOTBLOCK this needs to be done anyway (or a special linker symbol kept across multiple stages is needed, which is likely not worth the speedup).
