2018-04-26cpu/x86: add limited runtime identity page mappingAaron Durbin
When employing PAGING_IN_CACHE_AS_RAM more areas need to be mapped in at runtime. Therefore, paging_identity_map_addr() is added to support adding identity mappings. Because there are a fixed amount of pages in cache-as-ram paging only the existing paging structures can be used. As such that's a limitation on what regions and length one can map. Using util/x86/x86_page_tables.go to generate page tables will always populate all the page directory pages. Therefore, 2MiB mappings are easy to map in.

2018-04-26drivers/uart: Add helper function to allow bit-bangingJulius Werner
In some cases it may be useful to be able to bitbang a UART, such as during early bring-up when a driver for the actual controller isn't available yet. On some platforms we may even want to use this permanently, such as on the SDM845 where the hardware UART controller needs to have firmware loaded and is thus unavailable for most of the bootblock. This patch adds some helper code that makes it easy to implement this on a platform, you just have to pass it a function to control the Tx pin state and it will do the rest. It relies on the mono_time API and is thus bound to microsecond timing granularity, but that seems to be barely good enough for 115200 baud if the bit times are calculated carefully.

2018-04-25arch/x86: add support for cache-as-ram pagingAaron Durbin
Processors, such as glk, need to have paging enabled while in cache-as-ram mode because the front end is agressive about fetching lines into the L1I cache. If the line is dirty and in the L1D then it writes it back to "memory". However, in this case there is no backing store so the cache-as-ram data that was written back transforms to all 0xff's when read back in causing corruption. In order to mitigate the failure add x86 architecture support for enabling paging while in cache-as-ram mode. A Kconfig variable, NUM_CAR_PAGE_TABLE_PAGES, determines the number of pages to carve out for page tables within the cache-as-ram region. Additionally, the page directory pointer table is also carved out of cache-as-ram. Both areas are allocated from the persist-across-stages region of cache-as-ram so all stages utilizing cache-as-ram don't corrupt the page tables. The two paging-related areas are loaded by calling paging_enable_for_car() with the names of cbfs files to load the initial paging structures from.

dimm_info.serial had a strange contract. The SPD spec defines a 4 byte serial number. dimm_info.serial required a 4 character ascii string with a null terminator.

There were only two callers that set the serial number: * haswell/raminit.c: already does a memcpy(serial, spd->serial, 4), so it already matches the new contract. * amd_late_init.c: Previously copied the last 4 characters. Requires decoding the serial number into a byte array. google/cyan/spd/spd.c: This could be updated to pass the serial number, but it uses a hard coded spd.bin.

For those cases it is nice to be able to bitbang certain protocols so that you can already get further in the boot flow while those drivers are still being worked on. We already have this support for I2C, but it would be nice to have something for SPI as well, since without SPI you're not going to boot very far. This patch adds a couple of helper functions that platforms can use to implement bit-banging SPI with minimal effort. It also adds a proof of concept implementation using the RK3399.

AMD's fixed MTRRs have RdDram and WrDram bits that route memory accesses to DRAM vs. MMIO. These are typically hidden for normal operation by clearing SYS_CFG[19] (MtrrFixDramModEn). According to BKDGs and AMD64 Programmer's Manual vol 2, this bit is clear at reset, should be set for configuration during POST, then cleared for normal operation. Attempting to modify the RdDram and WrDram settings without unhiding them causes a General Protection Fault. Add functions to enable and disable MtrrFixDramModEn. Unhide/hide as necessary when copying or writing the fixed MTRRs. Finally, modify sipi_vector.S to enable the bits prior to writing the fixed MTRRs and disable when complete.

2017-09-14usbdebug: Fix init and add support for postcarKyösti Mälkki
It was originally designed such that if usbdebug_init() was called before cbmem_initialize(), it would fetch the already-initialized state from CBMEM. This changed when cbmem_find() behaviour changed to require cbmem_initialize() to be called first. As a result, ramstage had to reinitialize all of the EHCI controller and USB endpoints on entry. This was slow, specially with AMD hardware where one can scan USB ports to probe for the debug dongle. For postcar and ramstage, move usbdebug entry such that it is triggered from CBMEM_INIT_HOOK instead of console_init(). Side-effect of this is usbdebug console shows 'coreboot-xxx ... starting...' line only for romstage. Initialisation for usbdebug is never done in postcar. If you have USBDEBUG_IN_ROMSTAGE=n, postcar will not have console output on usb either. While at it, fix also some other __PRE_RAM__ cases to ENV_ROMSTAGE and alike.

The original purpose of adjust_cpu_apic_entry() was to set up an APIC map. That map was effectively only used for mapping *default* APIC id to CPU number in the SMM handler. The normal AP startup path didn't need this mapping because it was whoever won the race got the next cpu number. Instead of statically calculating (and wrong) just initialize the default APIC id map when the APs come online. Once the APs are online the SMM handler is loaded and the mapping is utilized.

This patch adds the common acpi code.ACPI code is very similar accross different intel chipsets.This patch is an effort to move those code in common place so that it can be shared accross different intel platforms instead of duplicating for each platform. We are removing the common acpi files in src/soc/intel/common. This removes the acpi.c file which was previously in src/soc/common/acpi. The config for common acpi is SOC_INTEL_COMMON_BLOCK_ACPI which can be defined in SOC's Kconfig file in order to use the common ACPI code. This patch also includes the changes in APL platform to use the common ACPI block. TEST= Tested the patch as below: 1.Builds and system boots up with the patch. 2.Check all the ACPI tables are present in /sys/firmware/acpi/tables 3.Check SCI's are properly working as we are modifying the function to override madt. 4.Extract acpi tables like DSDT,APIC, FACP, FACS and decompile the by iasl and compare with good known tables. 5.Execute the extracted tables in aciexec to check acpi methods are working properly.

The addr32 prefix is required by binutils, because even when given an explicit address which is greater than 64KiB, it will throw a warning about truncation, and stupidly emit the opcode with a 16-bit addressing mode and the wrong address. However, in the case of LLVM, this doesn't happen, and is happy to just use 32-bit addressing whenever it may require it. This means that LLVM never really needs an explicit addr32 prefix to use 32-bit addressing in 16-bit mode.
