2013-01-04update CFLAGS for armv7David Hendricks
This updates $CFLAGS used for armv7. Most of them were just added to be consistent with what u-boot does. The important ones here are -march=armv7-a and -mthumb (to allow 16-bit Thumb instructions). I removed the hard float support because it got errors and coreboot should never use floats anyway. We're still having trouble with enums but I want to see how far it gets with this patch. Also, put the flags in a form that makes diffs easier to read. It's almost impossible otherwise. Finally, move some flags to the architecture Makefile, and rely on the fact that some are set for all architectures.

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.

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.

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.

2012-07-24Add microcode blob processingVadim Bendebury
When microcode storage in CBFS is enabled, the make system is supposed to generate the microcode blob and place it into the generated ROM image as a CBFS component. The microcode source representation does not change: it is still an array of 32 bit constants. This new addition compiles the array into a separate object file and then strips all sections but data. The raw data section is then included into CBFS as a file named 'microcode_blob.bin' of type 0x53, which is assigned to microcode storage.

Code can easily make the mistake of using uninitialized values or, in assembly, mistakenly dereferencing stack pointers when an address is desired. Set the stack to a non-zero value which is also (by testing) a pointer which will crash coreboot if used. This poisoning has uncovered at least one bug.

2012-07-13MPTAPLE: generate from devicetree.cbSven Schnelle
This patch adds support for autogenerating the MPTABLE from devicetree.cb. This is done by a write_smp_table() declared weak in mpspec.c. If the mainboard doesn't provide it's own function, this generic implementation is called. Syntax in devicetree.cb: ioapic_irq <APICID> <INTA|INTB|INTC|INTD> <INTPIN> The ioapic_irq directive can be used in pci and pci_domain devices. If there's no directive, the autogen code traverses the tree back to the pci_domain and stops at the first device which such a directive, and use that information to generate the entry according to PCI IRQ routing rules.

PCI Type 2 config was a strange and never-used config mechanism. It is unlikely that in the 13 years of coreboot's existence that type 2 was ever used; it just made life complicated for everyone. It lived long enough in coreboot to be replaced by mmioconf. Prior to making the device tree visible in romstage we want to get rid of type2. Delete two files we don't need any more (yay!). Replace two functions with one: pci_config_default, which returns a pointer to the default config method. At some future time this may change to mmio but for now it is old type1 style.

2012-07-03Fix the error message for romstage when .bss or .data are non-zeroRonald G. Minnich
The error message from romstage is annoying and misleading: "Do not use global variables in romstage" Because it can occur even when global variables are not used in some circumstances, but also because it gives you only a rough idea where to look. This change sucks but sucks less. We still don't know which file the problem is in but at least we know if it is data or bss. Replace the error message with something that provides more information and less guessing on the part of the script: ".bss is non-zero size in romstage which is not allowed -- global variable?" or ".data is non-zero size in romstage which is not allowed -- global variable?" To test: build coreboot as normal. It builds. Add char d[32]; to romstage.c and get the first error message; add int x = 32; to romstage.c and get the second.

The current code for initializing AP cpus has several shortcomings: - it assumes APIC IDs are sequential - it uses only the BSP for determining the AP count, which is bad if there's more than one physical CPU, and CPUs are of different type Note that the new code call cpu->ops->init() in parallel, and therefore some CPU code needs to be changed to address that. One example are old Intel HT enabled CPUs which can't do microcode update in parallel.
