2021-10-15Revert "vboot_logic: Set VB2_CONTEXT_EC_TRUSTED in verstage_main"Hsuan-ting Chen
This reverts commit 6260bf712a836762b18d80082505e981e040f4bc. Reason for revert: This CL did not handle Intel GPIO correctly. We need to add GPIO_EC_IN_RW into early_gpio_table for platforms using Intel SoC.

2021-09-16vboot_logic: Set VB2_CONTEXT_EC_TRUSTED in verstage_mainHsuan Ting Chen
vboot_reference is introducing a new field (ctx) to store the current boot mode in crrev/c/2944250 (ctx->bootmode), which will be leveraged in both vboot flow and elog_add_boot_reason in coreboot. In current steps of deciding bootmode, a function vb2ex_ec_trusted is required. This function checks gpio EC_IN_RW pin and will return 'trusted' only if EC is not in RW. Therefore, we need to implement similar utilities in coreboot. We will deprecate vb2ex_ec_trusted and use the flag, VB2_CONTEXT_EC_TRUSTED, in vboot, vb2api_fw_phase1 and set that flag in coreboot, verstage_main. Also add a help function get_ec_is_trusted which needed to be implemented per mainboard.

2021-09-08cpu/x86/tsc: Deduplicate Makefile logicAngel Pons
The code under `cpu/x86/tsc` is only compiled in when its `Makefile.inc` is included from platform (CPU/SoC) code and the `UDELAY_TSC` Kconfig option is enabled. Include `cpu/x86/tsc/Makefile.inc` once from `cpu/x86/Makefile.inc` and drop the now-redundant inclusions from platform code. Also, deduplicate the `UDELAY_TSC` guards.

2021-06-22soc/intel/{apl,cnl}: Remove FSP CAR optionArthur Heymans
One of the reason FSP-T support had to be kept in place was for Intel Bootguard. This now works with native CAR code, so there is no reason to keep FSP-T as an option for these platforms. APL did not even build with FSP_CAR and finding FSP-T using walkcbfs was only recently fixed using FMAP, so there can be no doubt that this option was never used with coreboot master.

2020-10-28soc/intel: deduplicate ACPI timer emulationMichael Niewöhner
The code for enabling ACPI timer emulation is the same for the SoCs SKL, CNL, ICL, TGL, JSL and EHL. Deduplicate it by moving it to common code. APL differs in not having the delay settings. However, the bits are marked as "spare" and BWG mentions there are no "reserved bit checks done". Thus, we can write them unconditionally without any effect. Note: The ACPI timer emulation can only be used by SoCs with microcode supporting CTC (Common Timer Copy) / ACPI timer emulation.

When "Maximum" is chosen, the highest possibly value from the MSR gets used. When a too strict limit is set, coreboot will die, printing an error message.

2018-10-25soc/intel: Consolidate FSP CAR setup and teardown codePraveen hodagatta pranesh
This patch adds following changes, - APL, CFL, DENVERTON soc's using same implementation to setup and teardown FSP CAR. Hence cache_as_ram_fsp.S from soc folder is cosolidated into one file and moved to common code CPU car folder. - exit_car_fsp.S is from APL, DNV soc folder is clubbed into one file and moved to common CPU car. - The new file apollolake/fspcar.c is addded to pass tempraminit parameters. - Coffee lake Soc uses FSPT to support Intel Security features like BootGuard verify boot and Measured boot. Add FSP CAR support for CFL by programming tempraminit parameters and add FSP_T_XIP default if FSP_CAR is selected. BUG= None TEST= Build for both CFL RVP11 & RVP8 and verified for successful CAR setup. Build for both leafhill and harcuvar platform by selecting CONFIG_FSP_CAR without errors.

2018-10-12drivers/intel/fsp2_0: Hook up IntelFSP repoPatrick Georgi
With https://github.com/IntelFsp/FSP/pull/4 merged, this allows using Intel's FSP repo (that we mirror) to build a complete BIOS ifd region with a simple coreboot build, automatically drawing in headers and binaries. This commit covers Apollolake, Coffeelake, Skylake, and Kabylake. Skylake is using Kabylake's FSP since its own is FSP 1.1 and Kabylake's also supports Skylake. Another candidate (given 3rdparty/fsp's content) is Denverton NS, but it requires changes to coreboot's FSP bindings to become compatible. Cannonlake, Whiskeylake require an FSP release.

2018-04-27soc/intel/apollolake: enable cache-as-ram paging for glkAaron Durbin
Add support and enalbe cache-as-ram paging for glk to work around a cache-as-ram corruption issue. glk executes verstage, romstage, and FSP-M directly out of cache-as-ram (just like apl). However, the front end on glk is very agressive about pulling cache lines into L1I for potential execution. When the snoops hit in the L1D and the cache lines are dirty the processor writes the line back. However, there is no backing store for the dirty lines to go. As such when the line is pulled back in the value is all 0xff's, corrupting cache-as-ram. To fix the issue one needs to enable paging with NX (no execute) permissions which prevents the above actions from happening because the TLB will indicate that shouldn't be fetched into the instruction cache since data will be marked no execute. The generated page tables are added to cbfs and only added to the COREBOOT cbfs as they are only consumed in the early cache-as-ram stages. The page tables generated with: $ go run util/x86/x86_page_tables.go \ --iomap_file=src/soc/intel/apollolake/glk_page_map.txt \ --metadata_base_address=0xfef00000 \ --pdpt_output_c_file=src/soc/intel/apollolake/pdpt.c \ --pt_output_c_file=src/soc/intel/apollolake/pt.c Merged address space: 00000000d0000000 -- 00000000fef00000 UC NX : 375 big 256 small 00000000fef00000 -- 00000000fef20000 WB NX : 0 big 32 small 00000000fef20000 -- 00000000fefc0000 WB : 0 big 160 small 00000000fefc0000 -- 00000000ff000000 WB NX : 0 big 64 small 00000000ff000000 -- 0000000100000000 WP : 8 big 0 small Total Pages of page tables: 5 Pages linked using base address of 0xfef00000.

2016-07-02soc/intel/apollolake: handle p2sb quirksAaron Durbin
The P2SB device is device 0xd and function 0. If hidden that causes the latter pci devices on function >= 1 to not be probed in the kernel. This is also a problem for coreboot if the P2SB device is hidden by FSP. That means the coreboot driver won't be ran. Therefore, provide hide and unhide functions for the P2SB device. The other quirk is to allow the GPIO devices to work correctly. Those devices are ACPI devices. However, their resources are sub-regions within the P2SB BAR. Sadly, linux doesn't handle ACPI devices being children of PCI devices. This leads to resource conflict errors when the P2SB device is visible. For the time being keep the P2SB device hidden, but also ensure the resources it is using are accounted for and reserved. The fallout of that is the PMC and SPI device are no longer probed by the kernel.

2016-04-02soc/intel/apollolake: use CAR code coherency for all CAR stagesAaron Durbin
The flush L1D to L2 operation was only being used when loading romstage from bootblock. However, when the FSP-M component is loaded no code coherency actions are taken. I suspect this is because the FSP-M component is larger than the 24KiB L1D and the entry point is early in the image. Thus, when loading the FSP-M component the earlier part of the image is flushed out to L2 in the process of loading the latter part of the component. Also, once verstage is introduced the same code coherency actions need to be taken as well. Therefore, position the apollolake code to handle all these cases.
