This patch changes the return type of gpio_base2_value() and related functions from int to uint32_t. This makes more sense now that board_id() and related functions (which are the primary use case) also return that type. It's unlikely that we'll ever read a strapping of 32 GPIOs in a row, but if we did, we'd probably want to treat it as unsigned.

2018-06-28smm: Add canary to end of stack and die() if a stack overflow occursRaul E Rangel
If CPU 0's stack grows to large, it will overflow into CPU 1's stack. If CPU 0 is handling the interrupt then CPU 1 should be in an idle loop. When the stack overflow occurs it will override the return pointer for CPU 1, so when CPU 0 unlocks the SMI lock, CPU 1 will attempt to return to a random address. This method is not foolproof. If code allocates some stack variables that overlap with the canary, and if the variables are never set, then the canary will not be overwritten, but it will have been skipped. We could mitigate this by adding a larger canary value if we wanted. I chose to use the stack bottom pointer value as the canary value because: * It will change per CPU stack. * Doesn't require hard coding a value that must be shared between the .S and .c. * Passing the expected canary value as a parameter felt like overkill. We can explore adding other methods of signaling that a stack overflow had occurred in a follow up. I limited die() to debug only because otherwise it would be very hard to track down. TEST=built on grunt with a small and large stack size. Then verified that one causes a stack overflow and the other does not.

2018-05-22Introduce bootblock self-decompressionJulius Werner
Masked ROMs are the silent killers of boot speed on devices without memory-mapped SPI flash. They often contain awfully slow SPI drivers (presumably bit-banged) that take hundreds of milliseconds to load our bootblock, and every extra kilobyte of bootblock size has a hugely disproportionate impact on boot speed. The coreboot timestamps can never show that component, but it impacts our users all the same. This patch tries to alleviate that issue a bit by allowing us to compress the bootblock with LZ4, which can cut its size down to nearly half. Of course, masked ROMs usually don't come with decompression algorithms built in, so we need to introduce a little decompression stub that can decompress the rest of the bootblock. This is done by creating a new "decompressor" stage which runs before the bootblock, but includes the compressed bootblock code in its data section. It needs to be as small as possible to get a real benefit from this approach, which means no device drivers, no console output, no exception handling, etc. Besides the decompression algorithm itself we only include the timer driver so that we can measure the boot speed impact of decompression. On ARM and ARM64 systems, we also need to give SoC code a chance to initialize the MMU, since running decompression without MMU is prohibitively slow on these architectures. This feature is implemented for ARM and ARM64 architectures for now, although most of it is architecture-independent and it should be relatively simple to port to other platforms where a masked ROM loads the bootblock into SRAM. It is also supposed to be a clean starting point from which later optimizations can hopefully cut down the decompression stub size (currently ~4K on RK3399) a bit more. NOTE: Bootblock compression is not for everyone. Possible side effects include trying to run LZ4 on CPUs that come out of reset extremely underclocked or enabling this too early in SoC bring-up and getting frustrated trying to find issues in an undebuggable environment. Ask your SoC vendor if bootblock compression is right for you.

2018-05-11devicetree: Add USB device typeDuncan Laurie
This commit adds support for describing USB ports in devicetree.cb. It allows a USB port location to be described in the tree with configuration information, and ACPI code to be generated that provides this information to the OS. A new scan_usb_bus() is added that will scan bridges for devices so a tree of ports and hubs can be created. The device address is computed with a 'port type' and a 'port id' which is flexible for SOC to handle depending on their specific USB setup and allows USB2 and USB3 ports to be described separately. For example a board may have devices on two ports, one with a USB2 device and one with a USB3 device, both of which are connected to an xHCI controller with a root hub: xHCI | RootHub | | USB2[0] USB3[2] device pci 14.0 on chip drivers/usb/acpi register "name" = ""Root Hub"" device usb 0.0 on chip drivers/usb/acpi register "name" = ""USB 2.0 Port 0"" device usb 2.0 on end end chip drivers/usb/acpi register "name" = ""USB 3.0 Port 2"" device usb 3.2 on end end end end end Change-Id: I64e6eba503cdab49be393465b535e139a8c90ef4 Signed-off-by: Duncan Laurie <dlaurie@google.com> Reviewed-on: https://review.coreboot.org/26169 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Furquan Shaikh <furquan@google.com>
2018-05-10bootmem: Keep OS memory map separate from the startJulius Werner
The patch series ending in 64049be (lib/bootmem: Add method to walk OS POV memory tables) expanded the bootmem framework to also keep track of memory regions that are only relevant while coreboot is still executing, such as the ramstage code and data. Mixing this into the exsting bootmem ranges has already caused an issue on CONFIG_RELOCATEABLE_RAMSTAGE boards, because the ramstage code in CBMEM is marked as BM_RAMSTAGE which ends up getting translated back to LB_RAM in the OS tables. This was fixed in 1ecec5f (lib/bootmem: ensure ramstage memory isn't given to OS) for this specific case, but unfortunately Arm boards can have a similar problem where their stack space is sometimes located in an SRAM region that should not be made available as RAM to the OS. Since both the resources made available to the OS and the regions reserved for coreboot can be different for each platform, we should find a generic solution to this rather than trying to deal with each issue individually. This patch solves the problem by keeping the OS point of view and the coreboot-specific ranges separate from the start, rather than cloning it out later. Ranges only relevant to the coreboot view will never touch the OS-specific layout, to avoid the problem of losing information about the original memory type of the underlying region that needs to be restored for the OS view. This both supersedes the RELOCATABLE_RAMSTAGE fix and resolves the problems on Arm boards.

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.

2018-04-12include/memory_info.h: Change serial number field from 5 bytes to 4Raul E Rangel
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. This change makes the serial field so it matches the SPD spec. smbios.c will then translate the byte array into hex and set it on the smbios table. 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.

Sometimes when bringing up a new board it can take a while until you have all the peripheral drivers ready. 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.
