2018-10-22intel: Use CF9 reset (part 2)Patrick Rudolph
Make use of the common CF9 reset in SOC_INTEL_COMMON_RESET. Also implement board_reset() as a "full reset" (aka. cold reset) as that is what was used here for hard_reset(). Drop soc_reset_prepare() thereby, as it was only used for APL. Also, move the global-reset logic. We leave some comments to remind us that a system_reset() should be enough, where a full_reset() is called now (to retain current behaviour) and looks suspicious. Note, as no global_reset() is implemented for Denverton-NS, we halt there now instead of issuing a non-global reset. This seems safer; a non-global reset might result in a reset loop.

2018-10-22reset: Provide new single-function reset APINico Huber
board_reset() replaces the existing common reset API. There is no common distinction between reset types across platforms, hence, common code could never decide which one to call. Currently only hard_reset() is used by common code. We replace these calls and provide a fall-back to the current hard_reset() implemen- tation. The fall-back will be removed along with hard_reset() after the transition of all boards.

2018-10-11selfboot: remove bounce buffersRonald G. Minnich
Bounce buffers used to be used in those cases where the payload might overlap coreboot. Bounce buffers are a problem for rampayloads as they need malloc. They are also an artifact of our x86 past before we had relocatable ramstage; only x86, out of the 5 architectures we support, needs them; currently they only seem to matter on the following chipsets: src/northbridge/amd/amdfam10/Kconfig src/northbridge/amd/lx/Kconfig src/northbridge/via/vx900/Kconfig src/soc/intel/fsp_baytrail/Kconfig src/soc/intel/fsp_broadwell_de/Kconfig The first three are obsolete or at least could be changed to avoid the need to have bounce buffers. The last two should change to no longer need them. In any event they can be fixed or pegged to a release which supports them. For these five chipsets we change CONFIG_RAMBASE from 0x100000 (the value needed in 1999 for the 32-bit Linux kernel, the original ramstage) to 0xe00000 (14 Mib) which will put the non-relocatable x86 ramstage out of the way of any reasonable payload until we can get rid of it for good. 14 MiB was chosen after some discussion, but it does fit well: o Fits in the 16 MiB cacheable range coreboot sets up by default o Most small payloads are well under 14 MiB (even kernels!) o Most large payloads get loaded at 16 MiB (especially kernels!) With this change in place coreboot correctly still loads a bzImage payload. Werner reports that the 0xe00000 setting works on his broadwell systems.

2018-10-08Move compiler.h to commonlibNico Huber
Its spreading copies got out of sync. And as it is not a standard header but used in commonlib code, it belongs into commonlib. While we are at it, always include it via GCC's `-include` switch. Some Windows and BSD quirk handling went into the util copies. We always guard from redefinitions now to prevent further issues.

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.

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.

2017-12-07boardid: Switch from Kconfig to weak functionsJulius Werner
This patch switches the board_id and ram_code helper framework to use weak functions rather than Kconfigs to determine whether the board supplies these IDs. This cuts down on the amount of boilerplate Kconfigs many boards have to set and also gives them more flexibility, such as being able to determine at runtime whether a given ID is present.

2017-12-07boardid: Minor clean up and standardizationJulius Werner
Merge the different coreboot table strapping ID structures into one because they're really just all the same, and I want to add more. Make the signature of the board_id() function return a uint32_t because that's also what goes in the coreboot table. Add a printk to the generic code handling strapping IDs in ramstage so that not every individual mainboard implementation needs its own print. (In turn, remove one such print from fsp1_1 code because it's in the way of my next patch.)

2017-12-06Kconfig: Remove BOARD_ID_MANUAL optionJulius Werner
The BOARD_ID_MANUAL and BOARD_ID_STRING options were introduced for the Urara board which is now long dead, and have never been used anywhere else. They were trying to do something that we usually handle with a separate SKU ID these days, whereas BOARD_ID is supposed to be reserved for different revisions of the same board/SKU. Get rid of it to make further refactoring of other options easier. Also shove some stuff back into the Urara mainboard that should've never crept into generic headers.
