2020-10-13src: Rename EM100Pro-specific SPI console Kconfig optionAngel Pons
To avoid confusion with `flashconsole` (CONSOLE_SPI_FLASH), prefix this option with `EM100Pro`. Looks like it is not build-tested, however.

2020-09-07ec/system76: Add console supportJeremy Soller
This adds support for line-buffered console output to System76 EC firmware. Once the print command is received, the EC firmware multiplexes the output to any enabled console on the EC. This can be a memory ringbuffer, a parallel port (using the keyboard connector), or i2c (using the battery connector). Once the entire buffer is sent, it sets the command register to 0, indicating completion. For more information, please see: https://github.com/system76/ec/blob/master/doc/debugging.md Tested on system76/lemp9 with CONSOLE_SYSTEM76_EC enabled.

2020-06-14console, PCI: Remove EARLY_PCI_BRIDGE support in verstageKyösti Mälkki
The purpose of pci_early_bridge_init() is to temporarily configure PCIe rootport (or PCI bridge) on bus 0 to configure PCI device BARs on the secondary bus. Currently used and tested only with UART_OXPCIE. Since those BARs do not reset on stage changes, it is not necessary to redo those steps for verstage or postcar. Note that the option does not really work with many of the later platforms where PCIe pins/links/lanes are configured late in FSP-M or similar blob.

2019-12-11printf: Automatically prefix %p with 0xJulius Werner
According to the POSIX standard, %p is supposed to print a pointer "as if by %#x", meaning the "0x" prefix should automatically be prepended. All other implementations out there (glibc, Linux, even libpayload) do this, so we should make coreboot match. This patch changes vtxprintf() accordingly and removes any explicit instances of "0x%p" from existing format strings. How to handle zero padding is less clear: the official POSIX definition above technically says there should be no automatic zero padding, but in practice most other implementations seem to do it and I assume most programmers would prefer it. The way chosen here is to always zero-pad to 32 bits, even on a 64-bit system. The rationale for this is that even on 64-bit systems, coreboot always avoids using any memory above 4GB for itself, so in practice all pointers should fit in that range and padding everything to 64 bits would just hurt readability. Padding it this way also helps pointers that do exceed 4GB (e.g. prints from MMU config on some arm64 systems) stand out better from the others.

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.

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.

2017-06-04console/flashsconsole: Add spi flash console for debuggingYouness Alaoui
If CONSOLE_SPI_FLASH config is enabled, we write the cbmem messages to the 'CONSOLE' area in FMAP which allows us to grab the log when we read the flash. This is useful when you don't have usb debugging, and UART lines are hard to find. Since a failure to boot would require a hardware flasher anyways, we can get the log at the same time. This feature should only be used when no alternative is found and only when we can't boot the system, because excessive writes to the flash is not recommended. This has been tested on purism/librem13 v2 and librem 15 v3 which run Intel Skylake hardware. It has not been tested on other archs or with a driver other than the fast_spi.

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.)
