2012-11-28Remove assembly coded log2 functionRonald G. Minnich
As we move to supporting other systems we need to get rid of assembly where we can. The log2 function in src/lib is identical to the assembly one (tested for all 32-bit signed integers :-) and takes about 10 ns to run as opposed to 5ns for the non-portable assembly version. While speed is good, I think we can spare the 15 ns or so we add to boot time by using the C version only. Change-Id: Icafa565eae282c85fa5fc01b3bd1f110cd9aaa91 Signed-off-by: Ronald G.

2012-11-13cros: Inform U-Boot via fake gpio when VGA Option ROM is loadedBill Richardson
This prepares the way for vboot to inform coreboot when it needs the VGA Option ROM loaded. Coreboot can't always know when it's needed (with keyboard-based dev-mode, coreboot can't tell if we're in dev-mode or not). By the time we get to U-Boot, it's too late, so we need two extra bits - one for vboot to tell coreboot to load the Option ROM and another for coreboot to let vboot know it's been done. This change sets up the communication, but doesn't act on it just yet. Even with this CL we always load the VGA Option ROM, so there's nothing to test. There should be no user-visible change.

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.

2012-08-04Make the device tree available in the rom stageStefan Reinauer
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.

We were handling vga, vga_first, vga_last, vga_onboard just to determine an onboard chip and the first plugin card. We were also traversing the devices manually instead of using the utility functions we have, for the chance that there are non-VGA cards we need to cope with (but why would they require VGA-style handling?)

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.

2012-07-05PCI Type2 config must dieRonald G. Minnich
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.

2012-05-01Allow device ID arrays in the PCI driver structureVadim Bendebury
Many PCI devices share the very same driver despite having different PCI device IDs, which causes a lot of copy and paste of driver definitions. This change introduces a way to specify the array of acceptable device IDs in a single driver entry. As an example the Intel {Sandy|Ivy} Bridge SATA driver is being modified to use a single driver structure for all different SATA controller flavors, a few more Ivy Bridge IDs are being added as well. BUG=none TEST=manual . modified coreboot brought up an Ivy Bridge platform all the way to Linux login screen.

They were reversed from the order that I would have expected - Device ID as the high 16 bits and the Vendor ID as the low 16.
