2018-12-21cpu/amd/geode_lx: Drop supportArthur Heymans
These chips are still using LATE_CBMEM which was agreed upon to be removed after release 4.7. It is now more than 1 year later and they still linger around. The work and review to bring this code up to date can happen on the 4.9 branch and then squashed together and merged back into mainline when done.

2018-12-20cpu/intel/common: decouple IA32_FEATURE_CONTROL lock from set_vmx()Matt DeVillier
Newer CPUs/SoCs need to configure other features via the IA32_FEATURE_CONTROL msr, such as SGX, which cannot be done if the msr is already locked. Create separate functions for setting the vmx flag and lock bit, and rename existing function to indicate that the lock bit will be set in addition to vmx flag (per Kconfig). This will allow Skylake/Kabylake (and others?) to use the common VMX code without breaking SGX, while ensuring no change in functionality to existing platforms which current set both together. Test: build/boot each affected platform, ensure no change in functionality Change-Id: Iee772fe87306b4729ca012cef8640d3858e2cb06 Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/c/30229 Reviewed-by: Nico Huber <nico.h@gmx.de> Reviewed-by: David Guckian Tested-by: build bot (Jenkins) <no-reply@coreboot.org>

Initially, I wanted to move only the Kconfig DISPLAY_MTRRS into the "Debug" menu. It turned out, though, that the code looks rather generic. No need to hide it in soc/intel/. To not bloat src/Kconfig up any further, start a new `Kconfig.debug` hierarchy just for debug options. If somebody wants to review the code if it's 100% generic, we could even get rid of HAVE_DISPLAY_MTRRS.

2018-11-21(console,drivers/uart)/Kconfig: Fix dependenciesNico Huber
The dependencies of CONSOLE_SERIAL and DRIVERS_UART were somehow backwards. Fix that. Now, CONSOLE_SERIAL depends on DRIVERS_UART, because it's using its interface. The individual UART drivers select DRIVERS_UART, because they implement the interface and depend on the common UART code. Some guards had to be fixed (using CONSOLE_SERIAL now instead of DRIVERS_UART). Some other guards that were only about compilation of units were removed. We want to build test as much as possible, right?

When the Haswell-specific monotonic timer is used on an ASRock H81M-HDS with a Pentium G3258, the following exception is generated, causing the system to hang.

This MSR only exists on Haswell-ULT CPUs. So, allow boards to use the TSC monotonic timer instead. They can do this by placing `select TSC_MONOTONIC_TIMER` in the mainboard Kconfig.

2018-07-30nb/intel/gm45: Use common code for SMM in TSEGArthur Heymans
This makes i82801ix use the common smm southbridge code to set up smm relocation and smi handler setup. This is needed in this change for the the smm relocation code relies on some southbridge functions provided in the common code. Some of the old code is kept for the Q35 qemu target. This also caches the TSEG region and therefore increases MTRR usage a little in some cases. Currently SMRR msr's are not set on model_1067x and model_6fx since this needs the MSRR enable bit and lock set in IA32_FEATURE_CONTROL. This will be handled properly in the subsequent parallel mp init patchset. Tested on Thinkpad X200: boots and going to and resuming from S3 still works fine.

2018-07-30cpu/intel/microcode: Add helper functions to get microcode infoRizwan Qureshi
Add 4 helper functions to get microcode info. * get_current_microcode_rev return the the version of the currently running microcode. * get_microcode_rev extract microcode revision from the given patch. * get_microcode_size extract microcode size from the given patch. * get_microcode_checksum extract checksum from the given patch. The simpler thing would be to just move the struct microcode to microcode.h so that the structure members can be dereferenced. To encapsulate the structure details added the helper functions. This information will be used in future to compare microcodes for update.

Logic: If vboot is not used and the tpm is not initialized in the romstage makes use of the ramstage driver to initialize the TPM globally without having setup calls in lower SoC level implementations. * Add TPM driver in ramstage chip init which calls the tpm_setup function. * Purge all occurrences of TPM init code and headers. * Only compile TIS drivers into ramstage except for vboot usage. * Remove Google Urara/Rotor TPM support because of missing i2c driver in ramstage.

2018-06-28smm: Add canary to end of stack and die() if a stack overflow occursRaul E Rangel
If CPU 0's stack grows to large, it will overflow into CPU 1's stack. If CPU 0 is handling the interrupt then CPU 1 should be in an idle loop. When the stack overflow occurs it will override the return pointer for CPU 1, so when CPU 0 unlocks the SMI lock, CPU 1 will attempt to return to a random address. This method is not foolproof. If code allocates some stack variables that overlap with the canary, and if the variables are never set, then the canary will not be overwritten, but it will have been skipped. We could mitigate this by adding a larger canary value if we wanted. I chose to use the stack bottom pointer value as the canary value because: * It will change per CPU stack. * Doesn't require hard coding a value that must be shared between the .S and .c. * Passing the expected canary value as a parameter felt like overkill. We can explore adding other methods of signaling that a stack overflow had occurred in a follow up. I limited die() to debug only because otherwise it would be very hard to track down. TEST=built on grunt with a small and large stack size. Then verified that one causes a stack overflow and the other does not.

2018-06-27smm: Push a null stack base pointerRaul E Rangel
When generating a backtrace we need an indicator when we have hit the beginning of the stack. The i386 ABI states that %ebp points to the next stack frame. NULL can be used to indicate the end of the stack. We could add a NULL return pointer at %ebp+4, but I decided to omit it since a NULL stack pointer can be used as an indicator that there is no return pointer.

Therefore disable WRPROT region entirely for all family F models. As an extreme example, just changing the location of a constant string passed to printk() has been witnessed to make a the boot fail early on in romstage.
