2019-02-22symbols.h: Add macro to define memlayout region symbolsJulius Werner
When <symbols.h> was first introduced, it only declared a handful of regions and we didn't expect that too many architectures and platforms would need to add their own later. However, our amount of platforms has greatly expanded since, and with them the need for more special memory regions. The amount of code duplication is starting to get unsightly, and platforms keep defining their own <soc/symbols.h> files that need this as well. This patch adds another macro to cut down the definition boilerplate. Unfortunately, macros cannot define other macros when they're called, so referring to region sizes as _name_size doesn't work anymore. This patch replaces the scheme with REGION_SIZE(name). Not touching the regions in the x86-specific <arch/symbols.h> yet since they don't follow the standard _region/_eregion naming scheme. They can be converted later if desired.

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.

2018-05-22Introduce 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.

Introduce new bootmem tags to allow more fine grained control over buffer allocation on various platforms.

BM_MEM_PAYLOAD : Memory where any kind of payload resides and that should not be touched by bootmem. Starting with this commit all bootmem methods will no longer see memory that is used by coreboot as usable RAM. Bootmem changes: * Introduce a weak function to add platform specific memranges. * Mark memory allocated by bootmem as BM_TAG_PAYLOAD. * Assert on failures. * Add _stack and _program as BM_MEM_RAMSTAGE. ARMv7 and ARMv8 specific changes: * Add _ttb and _postram_cbfs_cache as BM_MEM_RAMSTAGE. ARMv7 specific changes: * Add _ttb_subtables as BM_MEM_RAMSTAGE.

2017-03-28Remove libverstage as separate library and source file classJulius Werner
In builds without CONFIG_VBOOT_SEPARATE_VERSTAGE, verstage files are linked directly into the bootblock or the romstage. However, they're still compiled with a separate "libverstage" source file class, linked into an intermediate library and then linked into the final destination stage. There is no obvious benefit to doing it this way and it's unclear why it was chosen in the first place... there are, however, obvious disadvantages: it can result in code that is used by both libverstage and the host stage to occur twice in the output binary. It also means that libverstage files have their separate compiler flags that are not necessarily aligned with the host stage, which can lead to weird effects like <rules.h> macros not being set the way you would expect. In fact, VBOOT_STARTS_IN_ROMSTAGE configurations are currently broken on x86 because their libverstage code that gets compiled into the romstage sets ENV_VERSTAGE, but CAR migration code expects all ENV_VERSTAGE code to run pre-migration. This patch resolves these problems by removing the separate library. There is no more difference between the 'verstage' and 'libverstage' classes, and the source files added to them are just treated the same way a bootblock or romstage source files in configurations where the verstage is linked into either of these respective stages (allowing for the normal object code deduplication and causing those files to be compiled with the same flags as the host stage's files). Tested this whole series by booting a Kevin, an Elm (both with and without SEPARATE_VERSTAGE) and a Falco in normal and recovery mode.

A architecture-specific function, named bootmem_arch_add_ranges(), is added so that each architecture can add entries into the bootmem memory map. This allows for a common write_tables() implementation to avoid code duplication.

2016-03-09Makefile: Add build-time overlap check for programs loaded after corebootJulius Werner
On non-x86 platforms, coreboot uses the memlayout.ld mechanism to statically allocate the different memory regions it needs and guarantees at build time that there are no dangerous overlaps between them. At the end of its (ramstage) execution, however, it usually loads a payload (and possibly other platform-specific components) that is not integrated into the coreboot build system and therefore cannot provide the same overlap guarantees through memlayout.ld. This creates a dangerous memory hazard where a new component could be loaded over memory areas that are still in use by the code-loading ramstage and lead to arbitrary memory corruption bugs. This patch fills this gap in our build-time correctness guarantees by adding the necessary checks as a new intermediate Makefile target on route to assembling the final image. It will parse the memory footprint information of the payload (and other platform-specific post-ramstage components) from CBFS and compare it to a list of memory areas known to be still in use during late ramstage, generating a build failure in case of a possible hazard. BUG=chrome-os-partner:48008 TEST=Built Oak while moving critical regions in the way of BL31 or the payload, observing the desired build-time errors. Built Nyan, Jerry and Falco without issues for good measure.

This patch generalizes the approach previously used for ARM32 TTB_SUBTABLES to "auto-detect" whether a certain region was defined in memlayout.ld. This allows us to get rid of the explicit Kconfig for the TIMESTAMP region, reducing configuration redundancy and avoiding confusion when setting up future boards.
