* commonlib/region: Turn addrspace_32bit into a more official APIJulius Werner2021-04-211-5/+1
| | | | | | | | | | | | | | | | | | | We had the addrspace_32bit rdev in prog_loaders.c for a while to help represent memory ranges as an rdev, and we've found it useful for a couple of things that have nothing to do with program loading. This patch moves the concept straight into commonlib/region.c so it is no longer anchored in such a weird place, and easier to use in unit tests. Also expand the concept to the whole address space (there's no real need to restrict it to 32 bits in 64-bit environments) and introduce an rdev_chain_mem() helper function to make it a bit easier to use. Replace some direct uses of struct mem_region_device with this new API where it seems to make sense.

* program_loading: Replace prog_rdev() with raw start pointer and sizeJulius Werner2021-03-171-21/+13
| | | | | | | | | | | | | | | Since prog_locate() was eliminated, prog_rdev() only ever represents the loaded program in memory now. Using the rdev API for this is unnecessary if we know that the "device" is always just memory. This patch changes it to be represented by a simple pointer and size. Since some code still really wants this to be an rdev, introduce a prog_chain_rdev() helper to translate back to that if necessary.

* prog_loaders: Remove prog_locate()Julius Werner2021-03-171-19/+4
| | | | | | | | | | | | | | | | | This patch rewrites the last few users of prog_locate() to access CBFS APIs directly and removes the call. This eliminates the double-meaning of prog_rdev() (referring to both the boot medium where the program is stored before loading, and the memory area where it is loaded after) and makes sure that programs are always located and loaded in a single operation. This makes CBFS verification easier to implement and secure because it avoids leaking a raw rdev of unverified data outside the CBFS core code.

* cbfs: Remove prog_locate() for stages and rmodulesJulius Werner2021-03-161-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | This patch removes the prog_locate() step for stages and rmodules. Instead, the stage and rmodule loading functions will now perform the locate step directly together with the actual loading. The long-term goal of this is to eliminate prog_locate() (and the rdev member in struct prog that it fills) completely in order to make CBFS verification code safer and its security guarantees easier to follow. prog_locate() is the main remaining use case where a raw rdev of CBFS file data "leaks" out of cbfs.c into other code, and that other code needs to manually make sure that the contents of the rdev get verified during loading. By eliminating this step and moving all code that directly deals with file data into cbfs.c, we can concentrate the code that needs to worry about file data hashing (and needs access to cbfs_private.h APIs) into one file, making it easier to keep track of and reason about. This patch is the first step of this move, later patches will do the same for SELFs and other program types.

* selfboot: create selfboot_check function, remove check paramRonald G. Minnich2018-10-251-4/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The selfboot function was changed at some point to take a parameter which meant "check the allocated descriptors to see if they target regions of real memory." The region check had to be buried deep in the last step of loading since that is where those descriptors were created and used. An issue with the use of the parameter was that it was not possible for compilers to easily divine whether the check code was used, and it was hence possible for the code, and its dependencies, to be compiled in even if never used (which caused problems for the rampayload code). Now that bounce buffers are gone, we can hoist the check code to the outermost level. Further, by creating a selfload_check and selfload function, we can make it easy for compilers to discard unused code: if selfload_check is never called, all the code it uses can be discarded too.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Introduce bootblock self-decompressionJulius Werner2018-05-221-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* cbfs: new API and better program loadingAaron Durbin2015-06-021-7/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A new CBFS API is introduced to allow making CBFS access easier for providing multiple CBFS sources. That is achieved by decoupling the cbfs source from a CBFS file. A CBFS source is described by a descriptor. It contains the necessary properties for walking a CBFS to locate a file. The CBFS file is then decoupled from the CBFS descriptor in that it's no longer needed to access the contents of the file. All of this is accomplished using the regions infrastructure by repsenting CBFS sources and files as region_devices. Because region_devices can be chained together forming subregions this allows one to decouple a CBFS source from a file. This also allows one to provide CBFS files that came from other sources for payload and/or stage loading. The program loading takes advantage of those very properties by allowing multiple sources for locating a program. Because of this we can reduce the overhead of loading programs because it's all done in the common code paths. Only locating the program is per source.
