2014-05-06Introduce stage-specific architecture for corebootFurquan Shaikh
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.

Since the header is not compiled and linked together with an rmodule there needs to be a way of marking which symbol is the entry point. __rmodule_entry is the symbol used for knowing the entry point. There was a little churn in SMM modules to ensure an rmodule entry point symbol takes a single argument.

Divisor is a function of requested baudrate, platform-specific reference clock and amount of oversampling done on the UART reference. Calculate this parameter with divisor rounded to nearest integer. When building without option_table or when there is no entry for baud_rate, CONFIG_TTYS0_BAUD is used for default baudrate. For OxPCIe use of 4 MHz for reference was arbitrary giving correct divisor for 115200 but somewhat inaccurate for lower baudrates. Actual hardware is 62500000 with 16 times oversampling.

An additional complication is the presence of having a relocatable ramstage which creates another path with duplication.

2014-01-21CAR_GLOBAL: Define section details oncePatrick Georgi
Improve clang compatibility by dropping an opaque hack The section attribute was only ever meant for specifying section names, not their properties - otherwise they would have provided section(name,attribute,class) instead of only section(name). The hack to add attribute and class to the name, and commenting out the "real" definitions inserted by the compiler (see the terminating "#"), is refused by clang developers. This is a cleaner implementation in that the section is first declared with its properties, then used later-on, expecting that later conflicting declarations are ignored. It can still break in two ways: 1. The assembler or linker could complain about a section declared in two different ways. 2. The assembler could just use the latest declaration, not the first, to determine the section's properties. I won't sort these out unless they actually happen.

Also fixes a bug in the Google Snow mainboard where it would not correctly initialize the pinmux configuration for the SPI flash bus. During a normal SPI boot the IROM would already do that for you, but when booting from USB you have to do it yourself.

2013-12-09Refactor usage of walkcbfs to permit access to CBFS headersAlexandru Gagniuc
walkcbfs() is used only with ROMCC. Besides finding stages during the bootblock, it's also used when applying microcode updates during the bootblock phase. The function used to return only a pointer to the data of the CBFS file, while making the header completely inaccessible. Since the header contains the length of the CBFS file, the caller did not have a way to know how long the data was. Then, other conventions had to be used to determine the EOF, which might present problems if the user replaces the CBFS file. This is not an issue when jumping to a stage (romstage), but can present problems when accessing a microcode file which has not been NULL-terminated. Refactor walkcbfs_asm to return a pointer to the CBFS file header rather than the data. Rename walkcbfs() to walkcbfs_head(), and reimplement a new walkcbfs() based on walkcbfs_head(). Thus current usage of walkcbfs() remains unaffected. The code has been verified to run successfully under qemu. Subsequent patches will change usage of walkcbfs() to walkcbfs_head where knowing the length of the data is needed.

Dummy get_top_of_ram() is removed from romstage to fail already at build-time for cases where cbmem_initialize() would not complete.

This reverts commit de1fe7f655c549e8dce5b34218221890fa5ccc34.

2013-07-15ARM: Define custom ELF headers for ARM.Gabe Black
At least when building with the gnu toolchain, the headers the linker automatically generate save space for the actual ELF headers in one of the loadable segments. This creates two problems. First, the data you intended to be at the start of the image doesn't actually show up there, it's actually the ELF headers. Second, the ELF headers are essentially useless for firmware since there's currently nothing to tell you where they are, and even if there was, there isn't much of a reason to look at them. They're useful in userspace for, for instance, the dynamic linker, but not really in firmware. This change adds a PHDRS construct to each of the linker scripts used on ARM which define a single segment called to_load which does not have the flag set which would tell the linker to put headers in it. The first section defined in the script has ": to_load" to tell the linker which segment to put it in, and from that point on the other sections go in there by default.
