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.

2018-05-19lib/gnat: Drop Restriction `No_Exception_Propagation`Nico Huber
It turns out that even with the `-gnatp` switch to suppress runtime checks, the compiler is still allowed to generate them (it only doesn't have to). If we can't control generation of checks, we also can't make assumptions about propagation of their exceptions. The compiler warning that led to this change seems spurious, though (the check might be generated, but is dropped later). So we might revert this decision if the compiler can be fixed.

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.

2017-12-07boardid: Add helpers to read sku_id strapping into coreboot tablesJulius Werner
On many recent Chrome OS boards, the desire to unite more configurations under the same image has led to the need of a "SKU ID" that identifies different configurations of the same board (e.g. with certain optional components stuffed or not stuffed, or replaced with a comparable component). This is markedly different from the existing "board ID", because that is reserved to count "revisions" -- changes made to the same configuration over time during the development process. This patch adds support to have a mainboard define this SKU ID and pass it through the coreboot table like we already have for board IDs.

2017-06-21cr50: process uninitialized values gracefullyVadim Bendebury
The vboot code tries reading rollback protection indices from the TPM, and if the attempt to read returns TPM_E_BADINDEX, it decides that the TPM has not yet been initialized for the Chromebook use, and needs to be taken through the factory initialization sequence. TPM_E_BADINDEX is an internal representation of the TPM error 0x28b, generated on attempts to read a non existing NVMEM space. If the space exists, but has never been written the TPM returns error 0x14a. This condition (the space exists but not written) could happen if the previous factory initialization attempt was interrupted right after the space was created. Let's map this error to the same internal representation (TPM_E_BADINDEX) so that the Chrome OS device could recover when this condition occurs. BRANCH=reef, gru BUG=b:37443842 TEST=verified that the Pyro device stuck in TPM error state recovered when this patch was applied.

2017-06-13Consolidate reset API, add generic reset_prepare mechanismJulius Werner
There are many good reasons why we may want to run some sort of generic callback before we're executing a reset. Unfortunateley, that is really hard right now: code that wants to reset simply calls the hard_reset() function (or one of its ill-differentiated cousins) which is directly implemented by a myriad of different mainboards, northbridges, SoCs, etc. More recent x86 SoCs have tried to solve the problem in their own little corner of soc/intel/common, but it's really something that would benefit all of coreboot. This patch expands the concept onto all boards: hard_reset() and friends get implemented in a generic location where they can run hooks before calling the platform-specific implementation that is now called do_hard_reset(). The existing Intel reset_prepare() gets generalized as soc_reset_prepare() (and other hooks for arch, mainboard, etc. can now easily be added later if necessary). We will also use this central point to ensure all platforms flush their cache before reset, which is generally useful for all cases where we're trying to persist information in RAM across reboots (like the new persistent CBMEM console does). Also remove cpu_reset() completely since it's not used anywhere and doesn't seem very useful compared to the others.

2017-05-18cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logsJulius Werner
The 'cbmem -1' flag that cuts off console output before the last boot will ignore content from earlier stages if it was truncated due to lack of pre-CBMEM console space. This patch makes the "log truncated" message more specific and adds it as an additional cut-off marker to 'cbmem -1' to counteract that problem. Also raise the log level of the coreboot banner one step to BIOS_NOTICE to make it more likely to be included in the output for 'cbmem -1' to find. (I believe NOTICE is reasonable but I wouldn't want to go as far as WARN which should be reserved for actual problems. Of course this is not ideal, but then again, our whole log-level system really isn't... it would be better if we could make it always print a banner to the CBMEM console without affecting the UART at the same time, but that would require a larger amount of work.)
