2020-05-02acpi: Move ACPI table support out of arch/x86 (3/5)Furquan Shaikh
This change moves all ACPI table support in coreboot currently living under arch/x86 into common code to make it architecture independent. ACPI table generation is not really tied to any architecture and hence it makes sense to move this to its own directory. In order to make it easier to review, this change is being split into multiple CLs. This is change 3/5 which basically is generated by running the following command: $ git grep -iIl "arch/acpi" | xargs sed -i 's/arch\/acpi/acpi\/acpi/g' BUG=b:155428745 Change-Id: I16b1c45d954d6440fb9db1d3710063a47b582eae Signed-off-by: Furquan Shaikh <furquan@google.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/40938 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: HAOUAS Elyes <ehaouas@noos.fr>

.acpi_fill_ssdt() does not need to modify the device structure. This change makes the struct device * parameter to acpi_fill_ssdt() as const.

2020-03-25create stdio.h and stdarg.h for {,v}snprintfJoel Kitching
Sometimes coreboot needs to compile external code (e.g. vboot_reference) using its own set of system header files. When these headers don't line up with C Standard Library, it causes problems. Create stdio.h and stdarg.h header files. Relocate snprintf into stdio.h and vsnprintf into stdarg.h from string.h. Chain include these header files from string.h, since coreboot doesn't care so much about the legacy POSIX location of these functions. Also move va_* definitions from vtxprintf.h into stdarg.h where they belong (in POSIX). Just use our own definitions regardless of GCC or LLVM. Add string.h header to a few C files which should have had it in the first place.

2020-02-28superio/common: Validate devicetreePatrick Rudolph
As the SSDT generator for LDNs expects a "parent" PNP device for proper ACPI code generation, validate that it is present. Make sure the devicetree looks as expected and print a BUG message if that's not the case. Tested on HP Z220: No BUG message was printed.

2020-01-09acpi: Be more ACPI compliant when generating _UIDPatrick Rudolph
* Add function to generate unique _UID using CRC32 * Add function to write the _UID based on a device's ACPI path ACPI devices that have the same _HID must use different _UID. Linux doesn't care about _UID if it's not used. Windows 10 verifies the ACPI code on boot and BSODs if two devices with the same _HID share the same _UID. Fixes BSOD seen on Windows 10.

Add a generic SuperIO ACPI generator, dropping the need to include additional code in DSDT for SuperIO. It generates a device HID based on the decoded I/O range. Tested on Supermicro X11SSH-TF using AST2400. The SSDT contains no errors and all devices are present.
