* Allow to build romstage sources inside the bootblockArthur Heymans2023-11-092-2/+3
| | | | | | | | | | | | | | | | | | | | | | | Having a separate romstage is only desirable: - with advanced setups like vboot or normal/fallback - boot medium is slow at startup (some ARM SOCs) - bootblock is limited in size (Intel APL 32K) When this is not the case there is no need for the extra complexity that romstage brings. Including the romstage sources inside the bootblock substantially reduces the total code footprint. Often the resulting code is 10-20k smaller. This is controlled via a Kconfig option. TESTED: works on qemu x86, arm and aarch64 with and without VBOOT.

* commonlib,console,nb,sb,security: Add SPDX licenses to MakefilesMartin Roth2023-08-141-0/+2
| | | | | | | | | | | | | | | | | | | | | To help identify the licenses of the various files contained in the coreboot source, we've added SPDX headers to the top of all of the .c and .h files. This extends that practice to Makefiles. Any file in the coreboot project without a specific license is bound to the license of the overall coreboot project, GPL Version 2. This patch adds the GPL V2 license identifier to the top of all makefiles in the commonlib, console, northbridge, security, and southbridge directories that don't already have an SPDX license line at the top.

* lib: Hook up libhwbase in romstageJeremy Compostella2022-12-171-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It's hidden behind the configuration option `CONFIG_ROMSTAGE_LIBHWBASE'. This also adds some glue code to use the coreboot console for debug output and our monotonic timer framework as timer backend. Running Ada code in romstage and more particular libhwbase brings a few challenges as global initialized variables are not supported in Cache-As-Ram mode. 1. The libhwbase dynamic mmio driver implementation makes the Gnat compiler generate some global initialized variables. For this reason, when compiled for romstage or for romstage and ramstage the static mmio driver is enforced (`HWBASE_STATIC_MMIO'). 2. The Gnat compiler generates elaboration functions to initialize program data at runtime. These elaboration functions are called by the romstage_adainit() function. The data references symbols suffixed by `_E'. Even though these symbols, at compilation time, do not contain any data and are filled with zeros, the Gnat compiler installs them in the .data section. Since these symbols are actually filled with zeros, it is safe to install them in the .bss section. cf. https://docs.adacore.com/gnat_ugn-docs/html/gnat_ugn/gnat_ugn/elaboration_order_handling_in_gnat.html#elaboration-code This patch requires the libhwbase https://review.coreboot.org/c/libhwbase/+/69854 CL.

| | | | | | | | | | | | | | | | | A common use case when running coreboot on production systems is that only the CBMEM console (the one with the least impact on boot speed) is enabled. In this case, some of the code in the console subsystem has no effect. Due to the way it's all genericized over multiple consoles and tied together with function pointers, not all of this can be compile-time eliminated automatically, so this patch adds a little helper to facilitate that.

| | | | | | | | | | | | | | | | | | | | | | | | | | In order to provide the same loglevel prefixes and highlighting that were recently introduced for "interactive" consoles (e.g. UART) to "stored" consoles (e.g. CBMEM) but minimize the amont of extra storage space wasted on this info, this patch will write a 1-byte control character marker indicating the loglevel to the start of every line logged in those consoles. The `cbmem` utility will then interpret those markers and translate them back into loglevel prefixes and escape sequences as needed. Since coreboot and userspace log readers aren't always in sync, occasionally an older reader may come across these markers and not know how to interpret them... but that should usually be fine, as the range chosen contains non-printable ASCII characters that normally have no effect on the terminal. At worst the outdated reader would display one garbled character at the start of every line which isn't that bad. (Older versions of the `cbmem` utility will translate non-printable characters into `?` question marks.)

* console: Add ANSI escape sequences for highlightingJulius Werner2022-02-072-1/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds ANSI escape sequences to highlight a log line based on its loglevel to the output of "interactive" consoles that are meant to be displayed on a terminal (e.g. UART). This should help make errors and warnings stand out better among the usual spew of debug messages. For users whose terminal or use case doesn't support these sequences for some reason (or who simply don't like them), they can be disabled with a Kconfig. While ANSI escape sequences can be used to add color, minicom (the presumably most common terminal emulator for UART endpoints?) doesn't support color output unless explicitly enabled (via -c command line flag), and other terminal emulators may have similar restrictions, so in an effort to make this as widely useful by default as possible I have chosen not to use color codes and implement this highlighting via bolding, underlining and inverting alone (which seem to go through in all cases). If desired, support for separate color highlighting could be added via Kconfig later.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Chromebooks normally run with non-serial enabled firmware because writing to the UART console is very slow. This unfortunately makes debugging boot errors more difficult. We tend to rely on port 80s and/or the vboot recovery code. When CONSOLE_CBMEM_DUMP_TO_UART is selected it will dump the entire cbmem console to the UART whenever `vboot_reboot()` is called. We don't incur any boot time penalty in the happy path, but still retain the ability to access the logs when an error occurs. The previous implementation was using a hard coded UART index and `get_uart_baudrate` was always returning 0 since `CONFIG_TTYS0_BAUD` wasn't defined. This change makes it so the UART console properties are available when CONSOLE_CBMEM_DUMP_TO_UART is set. This results in the following .config diff: +CONFIG_UART_FOR_CONSOLE=0 +CONFIG_TTYS0_BASE=0x3f8 +CONFIG_TTYS0_LCS=3 +CONFIG_CONSOLE_SERIAL_115200=y +CONFIG_TTYS0_BAUD=115200 This functionality is especially helpful on Guybrush.

Also the addresses of relocatable ramstage are currently not normalised on the logs, so util/genprof would be unable dress those.

* console/init: Drop CONSOLE_LEVEL_CONSTNico Huber2020-10-261-20/+5
| | | | | | | | | | | | | | | | | | | | | | We limited the configurability of the debug level to stages that have a `.data` section. This is not really a requirement, because a `.bss` section should suffice and we always have that now. We want to make the debug level configurable early but also want to avoid calling get_option() early, as an error therein could result in no console output at all. Hence, we compromise and start using get_option() from the second console init on. TEST=Booted QEMU once with `debug_level=Debug` and once with `debug_level=Notice`. On the second boot, most messages vanished for all stages but the bootblock.

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