2018-02-21driver/uart: Introduce a way for mainboard to override the baudrateJulien Viard de Galbert
The rationale is to allow the mainboard to override the default baudrate for instance by sampling GPIOs at boot. A new configuration option is available for mainboards to select this behaviour. It will then have to define the function get_uart_baudrate to return the computed baudrate.

2017-03-28vboot: Select SoC-specific configuration for all Chrome OS boardsJulius Werner
Some Chrome OS boards previously didn't have a hardcoded vboot configuration (e.g. STARTS_IN_BOOTBLOCK/_ROMSTAGE, SEPARATE_VERSTAGE, etc.) selected from their SoC and mainboard Kconfig files, and instead relied on the Chrome OS build system to pass in those options separately. Since there is usually only one "best" vboot configuration for a certain board and there is often board or SoC code specifically written with that configuration in mind (e.g. memlayout), these options should not be adjustable in menuconfig and instead always get selected by board and SoC Makefiles (as opposed to some external build system). (Removing MAINBOARD_HAS_CHROMEOS from Urara because vboot support for Pistachio/MIPS was never finished. Trying to enable even post-romstage vboot leads to weird compiler errors that I don't want to track down now. Let's stop pretending this board has working Chrome OS support because it never did.)

2016-06-12Kconfig: Set VBOOT_OPROM_MATTERS for relevant non-x86 devicesJulius Werner
The VBOOT_OPROM_MATTERS configuration option signals to vboot that the board can skip display initialization in the normal boot path. It's name is a left-over from a time when this could only happen by avoiding loading the VGA option ROM on x86 devices. Now we have other boards that can skip their native display initialization paths too, and the effect to vboot is the same. (Really, we should rename oprom_matters and oprom_loaded to display_skippable and display_initialized or something, but I don't think that's worth the amount of repositories this would need to touch.) The only effect this still has in today's vboot is to reboot and explicitly request display initialization for EC software sync on VBOOT_EC_SLOW_UPDATE devices (which we haven't had yet on ARM). Still, the vboot flag just declares the capability (for skipping display init), and it should be set correctly regardless of whether that actually makes a difference on a given platform (right now). This patch updates all boards/SoCs that have a conditional path based on display_init_required() accordingly.

2016-04-07edid: Make framebuffer row alignment configurableJulius Werner
Our EDID code had always been aligning the framebuffer's bytes_per_line (and x_resolution dependent on that) to 64. It turns out that this is a controller-dependent parameter that seems to only really be necessary for Intel chipsets, and commit 6911219cc (edid: Add helper function to calculate bits-per-pixel dependent values) probably actually broke this for some other controllers by applying the alignment too widely. This patch makes it explicitly configurable and depends the default on ARCH_X86 (which seems to be the simplest and least intrusive way to make it fit most cases for now... boards where this doesn't apply can still override it manually by calling edid_set_framebuffer_bits_per_pixel() again).

2016-03-24edid: Add helper function to calculate bits-per-pixel dependent valuesJulius Werner
Coreboot and most payloads support three basic pixel widths for the framebuffer. It assumes 32 by default, but several chipsets need to override that value with whatever else they're supporting. Our struct edid contains multiple convenience values that are directly derived from this (and other properties), so changing the bits per pixel always requires recalculating all those dependents in the chipset code. This patch provides a small convenience wrapper that can be used to consistently update the whole struct edid with a new pixel width instead, so we no longer need to duplicate those calculations everywhere. BUG=None TEST=Booted Oak in all three pixel widths (which it conveniently all supports), confirmed that images looked good.

coreboot passes information about the serial port implementation to payloads through a cbtables entry. We set the register width to 1 on most SoCs because that looked as good a default as any, but checking the uart structs they use, it's 4 for all of them.

2016-02-12tegra132/210: Remove memlayout_vboot2.ldJulius Werner
Having two separate memlayouts is an unnecessary complication. Contributors need to make sure that their code fits into the vboot one (with smaller stage sizes) either way, and the Tegras have plenty of SRAM anyway. Let's just make the vboot layout the default (as it was done on other SoCs) to keep things easier to maintain. The empty SRAM holes on non-vboot systems where the verstage and work buffer would've been won't hurt them.

This patch generalizes the approach previously used for ARM32 TTB_SUBTABLES to "auto-detect" whether a certain region was defined in memlayout.ld. This allows us to get rid of the explicit Kconfig for the TIMESTAMP region, reducing configuration redundancy and avoiding confusion when setting up future boards.

2015-11-16arm64: Implement generic stage transitions for non-Tegra SoCsJulius Werner
The existing arm64 architecture code has been developed for the Tegra132 and Tegra210 SoCs, which only start their ARM64 cores in ramstage. It interweaves the stage entry point with code that initializes a CPU (and should not be run again if that CPU already ran a previous stage). It also still contains some vestiges of SMP/secmon support (such as setting up stacks in the BSS instead of using the stage-peristent one from memlayout). This patch splits those functions apart and makes the code layout similar to how things work on ARM32. The default stage_entry() symbol is a no-op wrapper that just calls main() for the current stage, for the normal case where a stage ran on the same core as the last one. It can be overridden by SoC code to support special cases like Tegra. The CPU initialization code is split out into armv8/cpu.S (similar to what arm_init_caches() does for ARM32) and called by the default bootblock entry code. SoCs where a CPU starts up in a later stage can call the same code from a stage_entry() override instead. The Tegra132 and Tegra210 code is not touched by this patch to make it easier to review and validate. A follow-up patch will bring those SoCs in line with the model. BRANCH=None BUG=None TEST=Booted Oak with a single mmu_init()/mmu_enable(). Built Ryu and Smaug.

2015-11-11arm/arm64: Generalize bootblock C entry pointJulius Werner
When we first added ARM support to coreboot, it was clear that the bootblock would need to do vastly different tasks than on x86, so we moved its main logic under arch/. Now that we have several more architectures, it turns out (as with so many things lately) that x86 is really the odd one out, and all the others are trying to do pretty much the same thing. This has already caused maintenance issues as the ARM32 bootblock developed and less-mature architectures were left behind with old cruft. This patch tries to address that problem by centralizing that logic under lib/ for use by all architectures/SoCs that don't explicitly opt-out (with the slightly adapted existing BOOTBLOCK_CUSTOM option). This works great out of the box for ARM32 and ARM64. It could probably be easily applied to MIPS and RISCV as well, but I don't have any of those boards to test so I'll mark them as BOOTBLOCK_CUSTOM for now and leave that for later cleanup.

2015-11-11arm64: mmu: Make page table manipulation work across stagesJulius Werner
In order to have a proper runtime-modifyable page table API (e.g. to remap DRAM after it was intialized), we need to remove any external bookkeeping kept in global variables (which do not persist across stages) from the MMU code. This patch implements this in a similar way as it has recently been done for ARM32 (marking free table slots with a special sentinel value in the first PTE that cannot occur as part of a normal page table). Since this requires the page table buffer to be known at compile-time, we have to remove the option of passing it to mmu_init() at runtime (which I already kinda deprecated before). The existing Tegra chipsets that still used it are switched to instead define it in memlayout in a minimally invasive change. This might not be the best way to design this overall (I think we should probably just throw the tables into SRAM like on all other platforms), but I don't have a Tegra system to test so I'd rather keep this change low impact and leave the major redesign for later. Also inlined some single-use one-liner functions in mmu.c that I felt confused things more than they cleared up, and fixed an (apparently harmless?) issue with forgetting to mask out the XN page attribute bit when casting a table descriptor to a pointer.
