2018-12-04acpi_pld: Make it easier to define the ACPI USB device groupsDuncan Laurie
The Linux kernel can use the ACPI _PLD group information to determine peer ports. Currently to define the group information the devicetree must provide a complete _PLD structure. This change pulls the group information into a separate structure that can be defined in devicetree. This makes it easier to set for USB devices in devicetree that do not need a full custom PLD. This was tested on a sarien board with the USB devices defined by verifying that the USB 2/3 ports are correctly identified with their peer in sysfs.

2018-11-23arch/x86: drop special case cbfs locatorPatrick Georgi
CBFS used to have a special region for the x86 bootblock, which also contained a pointer to a CBFS master header, which describes the layout of the CBFS. Since we adopted other architectures, we got rid of the bootblock region as a separate entity and add the x86 bootblock as a CBFS file now. The master header still exists for compatibility with old cbfstool versions, but it's neatly wrapped in either the bootblock file or in a file carefully crafted at the right location (on all other architectures). All the layout information we need is now available from FMAP, a core part of a contemporary coreboot image, even on x86, so we can just use the generic master header locator in src/lib/cbfs.c and get rid of the special version. Among the advantages: the x86 header locator reduced the size of the CBFS by 64 bytes assuming that there's the bootblock region of at least that size - this breaks assumptions elsewhere (eg. when walking CBFS in cbfs_boot_locate() because the last file, the bootblock, will exceed the CBFS region as seen by coreboot (since it's CBFS - 64bytes).

Change 76ab2b7 ("arch/x86: allow global .bss objects without CAR_GLOBAL") allowed use of global .bss objects and hence moved around the macros resulting in car_active returning 0 even for those boards where CAR is actually active but do not require global migration. This resulted in boards getting stuck when doing a reset in verstage because the code flow incorrectly assumed that there was no CAR active and hence triggered a cache invalidate. This change fixes the above issue by returning 1 for car_active if ENV_CACHE_AS_RAM is set even if global migration is not required.

2018-11-05riscv: add support to block smp in each stageXiang Wang
Each stage performs some basic initialization (stack, HLS etc) and then call smp_pause to enter the single-threaded state. The main work of each stage is executed in a single-threaded state, and the multi-threaded state is restored by call smp_resume while booting the next stage.

2018-11-05riscv: add support smp_pause / smp_resumeXiang Wang
See https://doc.coreboot.org/arch/riscv/ we know that we need to execute smp_pause at the start of each stage and smp_resume at the end of each stage.

2018-11-01arch/x86: clarify raw CAR_GLOBAL access guardsAaron Durbin
Romstage is where DRAM comes online. Therefore, allow raw CAR_GLOBAL object access in all cache-as-ram stages that are not romstage. In practice, this should be a nop. However, the explicit check for romstage is clearer.

2018-11-01arch/x86: allow global .bss objects without CAR_GLOBALAaron Durbin
For platforms utilizing CONFIG_NO_CAR_GLOBAL_MIGRATION there's no need to automatically migrate globals. Because of this it's possible to automatically allow for uninitialized global variables which reside in the .bss section without needing to decorate those objects with CAR_GLOBAL.

2018-10-25selfboot: create selfboot_check function, remove check paramRonald G. Minnich
The selfboot function was changed at some point to take a parameter which meant "check the allocated descriptors to see if they target regions of real memory." The region check had to be buried deep in the last step of loading since that is where those descriptors were created and used. An issue with the use of the parameter was that it was not possible for compilers to easily divine whether the check code was used, and it was hence possible for the code, and its dependencies, to be compiled in even if never used (which caused problems for the rampayload code). Now that bounce buffers are gone, we can hoist the check code to the outermost level. Further, by creating a selfload_check and selfload function, we can make it easy for compilers to discard unused code: if selfload_check is never called, all the code it uses can be discarded too.
