2021-11-25arch/{arm,arm64,ppc64,riscv}: Add noop cpu_relaxRaul E Rangel
The cpu_relax method is defined for x86. This CL adds a no-op method so that it can be used in common code.

2021-07-09ppc64/byteorder.h: define use of big endianKrystian Hebel
All of the build configuration is set to produce big endian image on PPC64. In addition, the toolchain produced by coreboot-sdk does not include little endian libraries so it is not possible to build LE image even when that configuration is changed. This patch changes byte order definition which is required for proper work of functions that deal with endianness, like read_{le,be}*() or {le,be}*toh(). It also revealed bugs related to the endianness on BE targets that are addressed in the following patches.

2020-06-13treewide: Add Kconfig variable MEMLAYOUT_LD_FILEFurquan Shaikh
This change defines a Kconfig variable MEMLAYOUT_LD_FILE which allows SoC/mainboard to provide a linker file for the platform. x86 already provides a default memlayout.ld under src/arch/x86. With this new Kconfig variable, it is possible for the SoC/mainboard code for x86 to provide a custom linker file as well. Makefile.inc is updated for all architectures to use this new Kconfig variable instead of assuming memlayout.ld files under a certain path. All non-x86 boards used memlayout.ld under mainboard directory. However, a lot of these boards were simply including the memlayout from SoC. So, this change also updates these mainboards and SoCs to define the Kconfig as required. BUG=b:155322763 TEST=Verified that abuild with --timeless option results in the same coreboot.rom image for all boards.

Previously, CBMEM console detected on-the-fly that CAR migration had happened and relocated cbmem_console_p accoringlin with car_sync_var(). However, if the CAR_GLOBAL pointing to another object inside CAR is a relative offset instead, we have a more generic solution that can be used with timestamps code as well.

2019-07-12arch, include, soc: Use common stdint.hJacob Garber
There are only minimal differences between the architecture specific stdint.h implementations, so let's tidy them up and merge them together into a single file. In particular, - Use 'unsigned long' for uintptr_t. This was already the case for x86 and riscv, while arm and mips used 'unsigned int', and arm64 and ppc64 used 'unsigned long long'. This change allows using a single integer type for uintptr_t across all architectures, and brings it into consistency with the rest of the code base, which generally uses 'unsigned long' for memory addresses anyway. This change required fixing several assumptions about integer types in the arm code. - Use _Bool as the boolean type. This is a specialized boolean type that was introduced in C99, and is preferrable over hacking booleans using integers. romcc sadly does not support _Bool, so for that we stick with the old uint8_t. - Drop the least and fast integer types. They aren't used anywhere in the code base and are an unnecessary maintenance burden. Using the standard fixed width types is essentially always better anyway. - Drop the UINT64_C() macro. It also isn't used anywhere and doesn't provide anything that a (uint64_t) cast doesn't. - Implement the rest of the MIN and MAX numerical limits. - Use static assertions to check that the integer widths are correct.
