2013-03-21coreboot: introduce romstage_handoff structureAaron Durbin
The romstage_handoff structure is intended to be a way for romstage and ramstage to communicate with one another instead of using sideband signals such as stuffing magic values in pci config or memory scratch space. Initially this structure just contains a single region that indicates to ramstage that it should reserve a memory region used by the romstage. Ramstage looks for a romstage_handoff structure in cbmem with an id of CBMEM_ID_ROMSTAGE_INFO. If found, it will honor reserving the region defined in the romstage_handoff structure.

2013-03-21ramstage: prepare for relocationAaron Durbin
The current ramstage code contains uses of symbols that cause issues when the ramstage is relocatable. There are 2 scenarios resolved by this patch: 1. Absolute symbols that are actually sizes/limits. The symbols are problematic when relocating a program because there is no way to distinguish a symbol that shouldn't be relocated and one that can. The only way to handle these symbols is to write a program to post process the relocations and keep a whitelist of ones that shouldn't be relocated. I don't believe that is a route that should be taken so fix the users of these sizes/limits encoded as absolute symbols to calculate the size at runtime or dereference a variable in memory containing the size/limit. 2. Absoulte symbols that were relocated to a fixed address. These absolute symbols are generated by assembly files to be placed at a fixed location. Again, these symbols are problematic because one can't distinguish a symbol that can't be relocated. The symbols are again resolved at runtime to allow for proper relocation. For the symbols defining a size either use 2 symbols and calculate the difference or provide a variable in memory containing the size.

2013-03-19rmodule: add ramstage supportAaron Durbin
Coreboot's ramstage defines certain sections/symbols in its fixed static linker script. It uses these sections/symbols for locating the drivers as well as its own program information. Add these sections and symbols to the rmodule linker script so that ramstage can be linked as an rmodule. These sections and symbols are a noop for other rmodule-linked programs, but they are vital to the ramstage. Also add a comment in coreboot_ram.ld to mirror any changes made there to the rmodule linker script.

2013-03-19x86: remove stack definition in linker scriptAaron Durbin
In order to prepare the ramstage to be linked by the rmodule linker the stack needs to be self-contained within the ramstage objects. The reasoning is that the rmodule linker provides a way to define a heap, but it doesn't currently have a region for the stack. The downside to this is that memory footprint of the ramstage can change when compared before this change. The size difference stems from the link ordering of the objects as the stack is now defined within c_start.S. The size fluctuation ranges from 0 to CONFIG_STACK_SIZE - 1 because of the previous behavior or aligning to CONFIG_STACK_SIZE. It should be noted that such an alignment is unnecessary for 32-bit x86 as the alignment requirement for the stacks are 4 byte alignment. Also the memory footprint is still dominated by CONFIG_RAMTOP and CONFIG_RAMBASE.

2013-03-19cbfstool locate: Rename -a align switch to -P for page sizeHung-Te Lin
cbfstool usage change: The "-a" parameter for "cbfstool locate" is switched to "-P/--page-size". The "locate" command was used to find a place to store ELF stage image in one memory page. Its argument "-a (alignment)" was actually specifying the page size instead of doing memory address alignment. This can be confusing when people are trying to put a blob in aligned location (ex, microcode needs to be aligned in 0x10), and see this: cbfstool coreboot.rom locate -f test.bin -n test -a 0x40000 # output: 0x44, which does not look like aligned to 0x40000. To prevent confusion, it's now switched to "-P/--page-size". Verified by building i386/axus/tc320 (with page limitation 0x40000): cbfstool coreboot.rom locate -f romstage_null.bin -n romstage -P 0x40000 # output: 0x44 Signed-off-by: Hung-Te Lin <hungte@chromium.org> Change-Id: I0893adde51ebf46da1c34913f9c35507ed8ff731 Reviewed-on: http://review.coreboot.org/2730 Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Tested-by: build bot (Jenkins)

2013-01-30Extend CBFS to support arbitrary ROM source media.Hung-Te Lin
Summary: Isolate CBFS underlying I/O to board/arch-specific implementations as "media stream", to allow loading and booting romstage on non-x86. CBFS functions now all take a new "media source" parameter; use CBFS_DEFAULT_MEDIA if you simply want to load from main firmware. API Changes: cbfs_find => cbfs_get_file. cbfs_find_file => cbfs_get_file_content. cbfs_get_file => cbfs_get_file_content with correct type. CBFS used to work only on memory-mapped ROM (all x86). For platforms like ARM, the ROM may come from USB, UART, or SPI -- any serial devices and not available for memory mapping. To support these devices (and allowing CBFS to read from multiple source at the same time), CBFS operations are now virtual-ized into "cbfs_media". To simplify porting existing code, every media source must support both "reading into pre-allocated memory (read)" and "read and return an allocated buffer (map)". For devices without native memory-mapped ROM, "cbfs_simple_buffer*" provides simple memory mapping simulation. Every CBFS function now takes a cbfs_media* as parameter. CBFS_DEFAULT_MEDIA is defined for CBFS functions to automatically initialize a per-board default media (CBFS will internally calls init_default_cbfs_media). Also revised CBFS function names relying on memory mapped backend (ex, "cbfs_find" => actually loads files). Now we only have two getters: struct cbfs_file *entry = cbfs_get_file(media, name); void *data = cbfs_get_file_content(CBFS_DEFAULT_MEDIA, name, type); Test results: - Verified to work on x86/qemu. - Compiles on ARM, and follow up commit will provide working SPI driver.

2013-01-12Implement GCC code coverage analysisStefan Reinauer
In order to provide some insight on what code is executed during coreboot's run time and how well our test scenarios work, this adds code coverage support to coreboot's ram stage. This should be easily adaptable for payloads, and maybe even romstage. See http://gcc.gnu.org/onlinedocs/gcc/Gcov.html for more information. To instrument coreboot, select CONFIG_COVERAGE ("Code coverage support") in Kconfig, and recompile coreboot. coreboot will then store its code coverage information into CBMEM, if possible. Then, run "cbmem -CV" as root on the target system running the instrumented coreboot binary. This will create a whole bunch of .gcda files that contain coverage information. Tar them up, copy them to your build system machine, and untar them. Then you can use your favorite coverage utility (gcov, lcov, ...) to visualize code coverage. For a sneak peak of what will expect you, please take a look at http://www.coreboot.org/~stepan/coreboot-coverage/ Change-Id: Ib287d8309878a1f5c4be770c38b1bc0bb3aa6ec7 Signed-off-by: Stefan Reinauer <reinauer@google.com> Reviewed-on: http://review.coreboot.org/2052 Tested-by: build bot (Jenkins) Reviewed-by: David Hendricks <dhendrix@chromium.org> Reviewed-by: Martin Roth <martin@se-eng.com> Reviewed-by: Ronald G.

The SMM GNVS pointer is normally updated only when the ACPI tables are created, which does not happen in the resume path. In order to restore this pointer it needs to be available at resume time. The method used to locate it at creation time cannot be used again as that magic signature is overwritten with the address itself. So a new CBMEM ID is added to store the 32bit address so it can be found again easily. A new function is defined to save this pointer in CBMEM which needs to be called when the ACPI tables are created in each mainboard when write_acpi_tables() is called. The cpu_index variable had to be renamed due to a conflict when cpu/cpu.h is added for the smm_setup_structures() prototype.

This change switches over to use getopt style options for everything but command and cbfs file name. - This allows us to simplify the coreboot Makefiles a bit - Also, add guards to include files - Fix some 80+ character lines - Add more detailed error reporting - Free memory we're allocating Signed-off-by: Stefan Reinauer <reinauer@google.com> Change-Id: Ia9137942deb8d26bbb30068e6de72466afe9b0a7 Reviewed-on: http://review.coreboot.org/1800 Tested-by: build bot (Jenkins) Reviewed-by: Ronald G.

2012-11-12oprom: Ensure that mode information is valid before putting it in the tables.Gabe Black
At least when CONFIG_CHROMEOS is turned on, it's possible for CONFIG_FRAMEBUFFER_KEEP_VESA_MODE to be set but for there not to be any valid information to put into the framebuffer coreboot table. That means that what's put in there is junk, probably all zeroes from the uninitialized global variable the mode information is stored in (mode_info). When a payload uses libpayload and turns on the coreboot framebuffer console, that console will attempt to scroll at some point and decrease the cursor's y coordinate until it is less than the number of rows claimed by the console. The number of rows is computed by taking the vertical resolution of the framebuffer and dividing it by the height of the font. Because the mode information was all zeroes, the coreboot table info is all zeroes, and that means that the number of rows the console claims is zero. You can't get the unsigned y coordinate of the cursor to be less than zero, so libpayload gets stuck in an infinite loop. The solution this change implements is to add a new function, vbe_mode_info_valid, which simply returns whether or not mode_info has anything in it. If not, the framebuffer coreboot table is not created, and libpayload doesn't get stuck.

pirq_routing_irqs assumed that only four links are available for PIRQ routing, INTA to INTD. Some chipsets provide more, up to INTH. When pirq_routing_irqs found a link number greater than 4 in the pirq table, it would not assign that IRQ. This is a shame, as it limits the flexibility of routing IRQs. Make the maximum number of links a Kconfig variable, and modify the code to respect it. This works beatifully on the VX900, which provides 8 routable interrupts. While we're at it, also refactor pirq_routing_irqs, and add some much needed comments. Rename pirq_routing_irqs to pirq_route_irqs to demistify the role of this function.

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.

We thought about two ways to do this change. The way we decided to try was to 1. drop all ops from devices in romstage 2. constify all devices in romstage (make them read-only) so we can compile static.c into romstage 3. the device tree "devices" can be used to read configuration from the device tree (and nothing else, really) 4. the device tree devices are accessed through struct device * in romstage only. device_t stays the typedef to int in romstage 5. Use the same static.c file in ramstage and romstage We declare structs as follows: ROMSTAGE_CONST struct bus dev_root_links[]; ROMSTAGE_CONST is const in romstage and empty in ramstage; This forces all of the device tree into the text area. So a struct looks like this: static ROMSTAGE_CONST struct device _dev21 = { #ifndef __PRE_RAM__ .ops = 0, #endif .bus = &_dev7_links[0], .path = {.type=DEVICE_PATH_PCI,{.pci={ .devfn = PCI_DEVFN(0x1c,3)}}}, .enabled = 0, .on_mainboard = 1, .subsystem_vendor = 0x1ae0, .subsystem_device = 0xc000, .link_list = NULL, .sibling = &_dev22, #ifndef __PRE_RAM__ .chip_ops = &southbridge_intel_bd82x6x_ops, #endif .chip_info = &southbridge_intel_bd82x6x_info_10, .next=&_dev22 }; Change-Id: I722454d8d3c40baf7df989f5a6891f6ba7db5727 Signed-off-by: Ronald G.

However, in the process of this change only the vboot shared data structure was passed on by coreboot, so when u-boot tried to update the ChromeOS specific ACPI entries, it would accidently overwrite the vboot data.
