2019-07-19src: Make implicit fall throughs explicitJacob Garber
Implicit fall throughs are a perpetual source of bugs and Coverity Scan issues, so let's squash them once and for all. GCC can flag implicit fall throughs using the -Wimplicit-fallthrough warning, and this should ensure no more enter the code base. However, many fall throughs are intentional, and we can use the following comment style to have GCC suppress the warning. switch (x) { case 1: y += 1; /* fall through */ case 2: y += 2; /* fall through - but this time with an explanation */ default: y += 3; } This patch adds comments for all remaining intentional fall throughs, and tweaks some existing fall through comments to fit the syntax that GCC expects.

The prototype of vprintk() is currently declared unconditionally, which prevents it from being used in situations where the console is disabled. The code will compile correctly, but not link, since the definition in console.c isn't being provided. This adds a shim around the declaration so that, like printk(), a call to vprintk() in this situation will expand to a no-op function instead.

2018-10-18console: Set default loglevel to 8 (SPEW) for CONFIG_CHROMEOSJulius Werner
CB:26053 changed coreboot's default loglevel from SPEW to DEBUG. This may be the most reasonable choice for most users that are mostly interested in the UART console. However, on Chrome OS devices the UART is disabled for production configurations anyway, and instead they rely heavily on the CBMEM console for remote debugging and bug reports. For these kinds of cases more info is almost always better, and you can't easily reproduce a remotely filed bug if you notice that you need some info that is only provided by BIOS_SPEW. On the other hand, the cost of logging extra info to the CBMEM console is pretty negligible. Therefore, let's bump the loglevel for CONFIG_CHROMEOS in particular back up to the maximum. (Unfortunately, it seems that you can't 'select' a choice option from another option, so this has to go in the console/Kconfig file.)

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.
