* Set armv7 up for cpu_info to work as on x86 (so threads can work)Ronald G. Minnich2014-08-064-2/+54
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On x86, cpu_info lives at the top of stack. Make the arm do that as well, as the threading model needs that and so will multicore support. As part of this change, make the stack size a power of 2. Also make it much smaller -- 2048 bytes is PLENTY for ram stage. Note that the small stack size is counterintuitive for rom stage. How can this work in rom stage, which needs a HUGE stack for lzma? The main use of STACK_SIZE has always been in ram stage; since 2002 or so it was to size per-core stacks (see, e.g., src/arch/x86/lib/c_start.S:.space CONFIG_MAX_CPUS*CONFIG_STACK_SIZE and, more recently, thread stacks. So, we define the STACK_TOP for rom and ram stage, but the STACK_SIZE has no real effect on the ROM stage (no hardware red zones on the stack) and hence we're ok with actually defining the "wrong" stack size. In fact, the coreboot_ram ldscript for armv7 sizes the stack by subtracting CONFIG_STACK_BOTTOM from CONFIG_STACK_TOP, so we replicate that arithmetic in bootblock.inc Observed stack usage in ramstage: BS: BS_PAYLOAD_LOAD times (us): entry 1 run 153887 exit 1 Jumping to boot code at 23104044 CPU0: stack: 02072800 - 02073000, lowest used address 020728d4, stack used: 1836 bytes entry = 23104044 Which means we do need 2K, not 1K.

* MP Spec: Correct the Virtual Wire assignmentMike Loptien2014-06-162-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Virtual Wire mode is set by writing 0 to the the MPTable Feature2 bit field 'IMCR'. The virtualwire variable was initially defined as writing a 1 to this bit field which would actually set PIC mode instead of Virtual Wire mode. However, nearly every mainboard called the MPTables with virtualwire = 0, which actually had the effect of setting Virtual Wire mode. I am correcting the definition but leaving the call to write the MPTables with virtualwire = 0, which is how most mainboards are already setting the tables up. See the MP Spec table 4-1 for more details: Bit 7: IMCRP. When the IMCR presence bit is set, the IMCR is present and PIC Mode is implemented; otherwise, Virtual Wire Mode is implemented. http://download.intel.com/design/archives/processors/pro/docs/24201606.pdf Change-Id: I039d88134aabd55166c2b68aa842bacbfcc0f42b Signed-off-by: Mike Loptien <mike.loptien@se-eng.com> Reviewed-on: http://review.coreboot.org/5977 Tested-by: build bot (Jenkins) Reviewed-by: Marc Jones <marc.jones@se-eng.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Edward O'Callaghan <eocallaghan@alterapraxis.com>

* Introduce stage-specific architecture for corebootFurquan Shaikh2014-05-066-82/+133
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make all three coreboot stages (bootblock, romstage and ramstage) aware of the architecture specific to that stage i.e. we will have CONFIG_ARCH variables for each of the three stages. This allows us to have an SOC with any combination of architectures and thus every stage can be made to run on a completely different architecture independent of others. Thus, bootblock can have an x86 arch whereas romstage and ramstage can have arm32 and arm64 arch respectively. These stage specific CONFIG_ARCH_ variables enable us to select the proper set of toolchain and compiler flags for every stage. These options can be considered as either arch or modes eg: x86 running in different modes or ARM having different arch types (v4, v7, v8). We have got rid of the original CONFIG_ARCH option completely as every stage can have any architecture of its own. Thus, almost all the components of coreboot are identified as being part of one of the three stages (bootblock, romstage or ramstage). The components which cannot be classified as such e.g. smm, rmodules can have their own compiler toolset which is for now set to *_i386. Hence, all special classes are treated in a similar way and the compiler toolset is defined using create_class_compiler defined in Makefile. In order to meet these requirements, changes have been made to CC, LD, OBJCOPY and family to add CC_bootblock, CC_romstage, CC_ramstage and similarly others. Additionally, CC_x86_32 and CC_armv7 handle all the special classes. All the toolsets are defined using create_class_compiler. Few additional macros have been introduced to identify the class to be used at various points, e.g.: CC_$(class) derives the $(class) part from the name of the stage being compiled. We have also got rid of COREBOOT_COMPILER, COREBOOT_ASSEMBLER and COREBOOT_LINKER as they do not make any sense for coreboot as a whole. All these attributes are associated with each of the stages.
