2018-06-15util/cbfstool: Support FIT payloadsPatrick Rudolph
In order to support booting a GNU/Linux payload on non x86, the FIT format should be used, as it is the defacto standard on ARM. Due to greater complexity of FIT it is not converted to simple ELF format. Add support for autodecting FIT payloads and add them as new CBFS_TYPE 'fit'. The payload is included as is, with no special header. The code can determine the type at runtime using the CBFS_TYPE field. Support for parsing FIT payloads in coreboot is added in a follow on commit. Compression of FIT payloads is not supported, as the FIT sections might be compressed itself. Starting at this point a CBFS payload/ can be either of type FIT or SELF. Tested on Cavium SoC.

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.

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.

2016-12-08commonlib: provide incoherent region deviceAaron Durbin
The MRC cache uses an incoherent mechanism for updating the cache contents in that it assumes memory mapped boot device access for checking against latest data for update. However, it uses another driver for updating the underlying storage area. In order to aid in moving the MRC cache over to using region_devices for updates provide an implementation of a region_device which performs reads and writes to different region_devices so that different drivers can be used transparently.

2016-11-30soc/intel/common: Add save/restore for variable MRC dataAndrey Petrov
Piggy-back on existing MRC cache infrastructure to store variable MRC data. Only one set of data can be valid at given point of time. Currently this magically happens because region alignment is forced to 0x1000 and region itself is of the same size. This needs to be somehow programmatically enforced.

2016-11-12riscv: start to use the configstring functionsRonald G. Minnich
These functions will allow us to remove hardcodes, as long as we can verify the qemu and lowrisc targets implement the configstring correctly. Hence, for the most part, we'll start with mainboard changes first. Define a new config variable, CONFIG_RISCV_CONFIGSTRING, which has a default value that works on all existing systems but which can be changed as needed for a new SOC or mainboard.
