2013-07-10cpu: Add CPU microcode file to cbfs with 16-byte alignmentAaron Durbin
On x86 there is a 16-byte alignment requirement for the addresses containing the CPU microcode. The cbfs files containing the microcode are used in memory-mapped fashion when loading new mircocode. Therefore, the data payload's address/offset of a cbfs file in flash dictates the resulting alignment. Fix this by processing the CPU microcode cbfs file separately as it uses $(CBFSTOOL) to find the proper location within the provided rom image.

2013-06-06qemu: add x86 cpuGerd Hoffmann
This patch adds a qemu x86 cpu chip. It has no initialization function as this isn't needed on virtual hardware. A virtual machine can have pretty much any CPU: qemu emulates a wide range of x86 CPUs (try 'qemu -cpu ? for a list), also with 'qemu -cpu host' the guest will see a cpu which is (almost) identical to the one on the host machine. So I've added X86_VENDOR_ANY as wildcard match for the cpu_table.

2013-05-16x86: add cache-as-ram migration optionAaron Durbin
There are some boards that do a significant amount of work after cache-as-ram is torn down but before ramstage is loaded. For example, using vboot to verify the ramstage is one such operation. However, there are pieces of code that are executed that reference global variables that are linked in the cache-as-ram region. If those variables are referenced after cache-as-ram is torn down then the values observed will most likely be incorrect. Therefore provide a Kconfig option to select cache-as-ram migration to memory using cbmem. This option is named CAR_MIGRATION. When enabled, the address of cache-as-ram variables may be obtained dynamically. Additionally, when cache-as-ram migration occurs the cache-as-ram data region for global variables is copied into cbmem. There are also automatic callbacks for other modules to perform their own migration, if necessary.

2013-02-27Fix microcode selection codeStefan Reinauer
The ARM CPUs we know of don't have CPU microcode updates, so don't show the selection in Kconfig. Also simplify (and fix) the microcode selection in the Makefile that would try to include microcode even though none is available.

2013-02-12armv7: Add emulation/qemu-armv7 board.Hung-Te Lin
To simplify testing ARM implementation, we need a QEMU configuration for ARM. The qemu-armv7 provides serial output, CBFS simulation, and full boot path (bootblock, romstage, ramstage) to verify the boot loader functionality. To run with QEMU: export QEMU_AUDIO_DRV=none qemu-system-arm -M vexpress-a9 -m 1024M -nographic -kernel build/coreboot.rom Verified to boot until ramstage loaded successfully by QEMU v1.0.50.

Samsung SoC files, including Exynos5 (a Cortex-A15 implementation). Since this is an SoC we'll forego the x86-style {north,south}bridge and cpu distinction. We may try to split some stuff out before the final version if prudent.

2012-09-05buildsystem: Make CPU microcode updating more configurableAlexandru Gagniuc
This patch aims to improve the microcode in CBFS handling that was brought by the last patches from Stefan and the Chromium team. Choices in Kconfig - 1) Generate microcode from tree (default) - 2) Include external microcode file - 3) Do not put microcode in CBFS The idea is to give the user full control over including non-free blobs in the final ROM image. MICROCODE_INCLUDE_PATH Kconfig variable is eliminated. Microcode is handled by a special class, cpu_microcode, as such: cpu_microcode-y += microcode_file.c MICROCODE_IN_CBFS should, in the future, be eliminated. Right now it is needed by intel microcode updating. Once all intel cpus are converted to cbfs updating, this variable can go away. These files are then compiled and assembled into a binary CBFS file. The advantage of doing it this way versus the current method is that 1) The rule is CPU-agnostic 2) Gives user more control over if and how to include microcode blobs 3) The rules for building the microcode binary are kept in src/cpu/Makefile.inc, and thus would not clobber the other makefiles, which are already overloaded and very difficult to navigate.
