2014-01-06CBMEM: Fix allocation for static CBMEMKyösti Mälkki
CBMEM console buffer size is adjustable in menuconfig, but this would not correctly adjust the overall allocation made for CBMEM. HIGH_MEMORY_SIZE is aligned to 64kB and definitions are moved down in the header file as HIGH_MEMORY_SIZE is not used with DYNAMIC_CBMEM. Try to continue boot even if CBMEM cannot be created. This error would only occur during development of new ports anyways and more log output is better.

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.

2013-12-06arch/x86: Do not run UPDATE-FIT if we don't include microcodeAlexandru Gagniuc
The original intention was to only run UPDATE_FIT when a microcode file was included in CBFS. This happens when either CPU_MICROCODE_CBFS_GENERATE or CPU_MICROCODE_CBFS_EXTERNAL is selected, however, the makefile checked that CPU_MICROCODE_IN_CBFS was selected instead. The end result was that on hasswell, the UPDATE-FIT step was always run, even when no microcode was included, generating a build error. Instead, introduce a new variable which tells if a microcode update is added in CBFS during the build.

2013-11-26Log device path into CMOS during probe stagesDuncan Laurie
One of the most common hangs during coreboot execution is during ramstage device init steps. Currently there are a set of (somewhat misleading) post codes during this phase which give some indication as to where execution stopped, but it provides no information on what device was actually being initialized at that point. This uses the new CMOS "extra" log banks to store the encoded device path of the device that is about to be touched by coreboot. This way if the system hangs when talking to the device there will be some indication where to investigate next. interrupted boot with reset button and gathered the eventlog after several test runs: 26 | 2013-06-10 10:32:48 | System boot | 120 27 | 2013-06-10 10:32:48 | Last post code in previous boot | 0x75 | Device Initialize 28 | 2013-06-10 10:32:48 | Extra info from previous boot | PCI | 00:16.0 29 | 2013-06-10 10:32:48 | Reset Button 30 | 2013-06-10 10:32:48 | System Reset Change-Id: I6045bd4c384358b8a4e464eb03ccad639283939c Signed-off-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-on: https://gerrit.chromium.org/gerrit/58105 Reviewed-on: http://review.coreboot.org/4230 Tested-by: build bot (Jenkins) Reviewed-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>

2013-11-19Add GRUB2 payload to build systemVladimir Serbinenko
Since a long time GRUB 2 is a viable payload alternative to SeaBIOS and FILO. So make it easy for coreboot users to use GRUB 2 as a payload by integrating it into coreboot’s build system, so it can be selected in Kconfig. As the last GRUB 2 release 2.00 is too old and has several bugs when used as a coreboot payload only allow to build GRUB 2 master until a new GRUB release is done. The downside is, that accidental breakage in GRUB’s upstream does not affect coreboot users. Currently the GRUB 2 payload is built with the default modules which results in an uncompressed size of around 730 kB. Compressed it has a size of 340 kB, so it should be useable with 512 kB flash ROMs. Tested with QEMU.

2013-08-15payload/SeaBIOS: Add SEABIOS_PS2_TIMEOUT Kconfig variablePeter Stuge
This allows mainboards to preconfigure a ps2-keyboard-spinup timeout when SeaBIOS is chosen as the payload. The Kconfig option can be changed manually if CONFIG_EXPERT is set.

2013-08-01Add directive __SIMPLE_DEVICE__Kyösti Mälkki
The tests for __PRE_RAM__ or __SMM__ were repeatedly used for detection if dev->ops in the devicetree are not available and simple device model functions need be used. If a source file build for ramstage had __PRE_RAM__ inserted at the beginning, the struct device would no longer match the allocation the object had taken. This problem is fixed by replacing such cases with explicit __SIMPLE_DEVICE__.

2013-07-25Redefine pci_bus_default_ops as functionKyösti Mälkki
Taking device_t as a parameter, this allows to alter the PCI config access handlers. This is useful to add tracing of PCI config writes for devices having problems to initialise correctly. On older AMD platform PCI MMIO may not be able to fully configure all PCI devices/nodes, while MMIO_SUPPORT_DEFAULT would be preferred due to its atomic nature. So those can be forced to IO config instead.

2013-07-22X86: make the SIPI num_starts a config variableRonald G. Minnich
The code to figure out how to set num_starts was starting to get kludgy. It's a constant for a given CPU; constants should be constant; make it a config variable. This change includes an example of how to override it. Build but not boot tested; drivers welcome. Change-Id: Iddd906a707bb16251615c7b42f2bfb5a044379b4 Signed-off-by: Ronald G.

2013-07-14SMBIOS: Allow overriding default Manufacturer and Product namesPeter Stuge
The vendor and part name from coreboot is normally stored in these SMBIOS structure fields, but it can be useful to override them. On Lenovo ThinkPads an override is e.g. needed to convince the Linux thinkpad_acpi.c driver that it is actually running on a ThinkPad.

2013-07-11Unify PCI configuration cyclesKyösti Mälkki
Split PCI IO configuration and MMIO configuration cycles to separate files. Modern hardware does not use IO cycles for PCI configuration after initial setup in bootblock. Note that the pci_mmio_ and pcie_ functions were different in masking the alignment for register address. PCI standard requires that 16-bit and 32-bit configuration register writes do not cross boundaries.
