The dependencies of CONSOLE_SERIAL and DRIVERS_UART were somehow backwards. Fix that. Now, CONSOLE_SERIAL depends on DRIVERS_UART, because it's using its interface. The individual UART drivers select DRIVERS_UART, because they implement the interface and depend on the common UART code. Some guards had to be fixed (using CONSOLE_SERIAL now instead of DRIVERS_UART). Some other guards that were only about compilation of units were removed.

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.)

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.

2017-05-18cbmem_console: Improve 'cbmem -1' behavior for truncated pre-CBMEM logsJulius Werner
The 'cbmem -1' flag that cuts off console output before the last boot will ignore content from earlier stages if it was truncated due to lack of pre-CBMEM console space. This patch makes the "log truncated" message more specific and adds it as an additional cut-off marker to 'cbmem -1' to counteract that problem. Also raise the log level of the coreboot banner one step to BIOS_NOTICE to make it more likely to be included in the output for 'cbmem -1' to find. (I believe NOTICE is reasonable but I wouldn't want to go as far as WARN which should be reserved for actual problems. Of course this is not ideal, but then again, our whole log-level system really isn't... it would be better if we could make it always print a banner to the CBMEM console without affecting the UART at the same time, but that would require a larger amount of work.)

2017-04-25console: rework log level to not be reliant on ROMSTAGE_CONSTAaron Durbin
The console log level variable doesn't really rely on ROMSTAGE_CONST proper. Instead, the mutability of the variable is based on the current implementation of ROMSTAGE_CONST (__PRE_RAM__). As such directly use that logic for the code. In addition, refactor the code to let the compiler and linker optimize out accesses instead of using the pre-processor.

If no maximum string length is specified, we're intentionally passing a value of -1 to get the string length so that it's not limited.

2016-10-02Kconfig: Update default hex values to start with 0xMartin Roth
Kconfig hex values don't need to be in quotes, and should start with '0x'. If the default value isn't set this way, Kconfig will add the 0x to the start, and the entry can be added unnecessarily to the defconfig since it's "different" than what was set by the default. A check for this has been added to the Kconfig lint tool.

2016-05-25console/post: be explicit about conditional cmos_post_log() compilingAaron Durbin
The current code was using !__PRE_RAM__ as a proxy for ramstage conditional compilation. In the face of postcar stage not defining __PRE_RAM__ (because it's after RAM is up) these code paths can fail to compile with a __SIMPLE_DEVICE__ defined for the entire stage. Remedy the current situation by just compiling explicity for ramstage because that was the original intent. In the future, the __SIMPLE_DEVICE__ selection for postcar can also be re-evaluated.
