The code can only be compiled as x86_32. Mark it as such to fix errors in the x86_64 assembler. The caller has to make sure to call this code in protected mode only.

2020-08-21arch/x86/gdt: Work around assembler bugPatrick Rudolph
The GDT loading did work fine on x86_64 a few months ago, but today it only works in QEMU, but not on real hardware or KVM-enabled QEMU. This might be related to toolchain changes. Use 64bit GDT loading on x86_64 and force the assembler to generate a 64bit address load on the GDT. This will make sure no 32bit (signed) displacement op is being generated, which points to the wrong address in longmode. Verified using readelf and made sure no R_X86_64_32S relocation symbol is emitted. Disassembled the romstage ELF and made sure the GDT address is 64bit in size. Tested on QEMU and KVM-enabled QEMU: Doesn't crash any more on KVM.

2020-08-21arch/x86: Add support for ASan to memory functionsHarshit Sharma
Compiler's instrumentation cannot insert asan memory checks in case of memory functions like memset, memcpy and memmove as they are written in assembly. So, we need to manually check the memory state before performing each of these operations to ensure that ASan is triggered in case of bad access.

2020-07-30smbios: Fix type 17 for Windows 10Patrick Rudolph
The `GetPhysicallyInstalledSystemMemory` API call, at least on Windows 10, returns an error if SMBIOS tables are invalid. Various tools use this API call and don't operate correctly if this fails. For example, the "Intel Processor Diagnostic Tool" program is affected. Windows then guesses the physical memory size by accumulating entries from the firmware-provided memory map, which results in a total memory size that is slightly lower than the actual installed memory capacity. To fix this issue, add the handle to a type 16 entry to all type 17 entries. Add new fields to struct memory_info and fill them in Intel common code. Use the introduced variables to fill type 16 in smbios.c and provide a handle to type 17 entries. Besides keeping the current behaviour on intel/soc/common platforms, the type 16 table is also emitted on platforms that don't explicitly fill it, by using the existing fields of struct memory_info. Tested on Windows 10: The GetPhysicallyInstalledSystemMemory API call doesn't return an error anymore and the installed memory is now being reported as 8192 MiB.

2020-07-07armv7: mmu: Use 'tlbimva' to invalidate TLB entriesSam Lewis
The tlbimvaa operation (invalidate unified TLB by MVA, all address space identifiers) is only available on armv7 processors that support Multiprocessing Extensions. When used on processors that do not support the extensions it causes an "undefined instruction" exception. This patch changes the MMU table entry filling code to use the tlbimva (invalidate unified TLB entry by MVA and address space identifier) operation for invalidating TLB entries, which is supported on all armv7 processors. As address space identifiers are not used in TLB entries in coreboot (all entries are set as global), these two operations can safely be used interchangeably. The ASID value supplied to the operation is not checked for global TLB entries. More information as well as the data formats for the tlbimvaa and tlbimva operations are detailed in the "ARM Architecture Reference Manual ARMv7-A" edition, issue "C.c" page B4-1747.

Kconfig 4.17 started using the $(..) syntax for environment variable expansion while we want to keep expansion to the build system. Older Kconfig versions (like ours) simply drop the escapes, not changing the behavior. While we could let Kconfig expand some of the variables, that only splits the handling in two places, making debugging harder and potentially messing with reproducible builds (e.g. when paths end up in configs), so escape them all.
