2022-06-01cbfs: Rename TYPE_FIT to TYPE_FIT_PAYLOADJulius Werner
There are too many "FIT" in firmware land. In order to reduce possible confusion of CBFS_TYPE_FIT with the Intel Firmware Interface Table, this patch renames it to CBFS_TYPE_FIT_PAYLOAD (including the cbfstool argument, so calling scripts will now need to replace `-t fit` with `-t fit_payload`).

2022-05-23cpu/x86/smm: Remove heapArthur Heymans
Currently no smihandler uses heap. coreboot's heap manager also is quite limited in what it will free (only the latest alloc). This makes it a bad idea to use it inside the smihandler, as depending on the alloc usage the heap might actually be full at some point, breaking the smihandler. This also reduces the ramstage by 448 bytes on google/vilboz.

2022-05-20lib/Makefile.inc: Add cbfs header pointer on !BOOTBLOCK_IN_CBFSArthur Heymans
On some x86 targets it the bootblock is loaded via a different mechanism, like via the AMD PSP or Intel IFWI. Some payloads need that pointer so add it to cbfs. Note that on Intel APL this file is not used, which is why the bootblock still needs to contain the pointer in the ARCH_X86 part. It is not worth it to add logic to specifically deal with APL as this is a legacy feature anyway. For AMD non-car platform this fixes cbfs access in SeaBIOS.

There are efforts to have bootflows that do not follow a traditional bootblock-romstage-postcar-ramstage model. As part of that CBMEM initialisation hooks will need to move from romstage to bootblock. The interface towards platforms and drivers will change to use one of CBMEM_CREATION_HOOK() or CBMEM_READY_HOOK(). Former will only be called in the first stage with CBMEM available.

2022-05-12Makefile.inc: Generate master header and pointer as C structsArthur Heymans
The makefiles don't like cbfs file names with spaces in them so update the file name with '_' instead of spaces. To keep the master header at the top of cbfs, add a placeholder. This removes the need to handle the cbfs master header in cbfstool. This functionality will be dropped in a later CL. On x86 reserve some space in the linker script to add the pointer. On non-x86 generate a pointer inside a C struct file. As a bonus this would actually fix the master header pointer mechanism on Intel/APL as only the bootblock inside IFWI gets memory mapped. TESTED on thinkpad X201: SeaBIOS correctly finds the cbfs master header.

Another reason to do this is the following: On some platforms that start in dram it makes little sense to have separate stages.

By storing the SMI logs into cbmem we can debug SMIs using `cbmem -1`. Now that these logs are available to the OS we could also verify there were no errors in the SMI handler. Since SMM can write to all of DRAM, we can't trust any pointers provided by cbmem after the OS has booted. For this reason we store the cbmem console pointer as part of the SMM runtime parameters.

2022-02-07console: Add loglevel marker codes to stored consolesJulius Werner
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.)

2022-01-25lib/cbmem_console,console: Resurrect CONSOLE_CBMEM_DUMP_TO_UARTRaul E Rangel
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.

2022-01-23lib/cbmem_console: Add cbmemc_copy_in functionRaul E Rangel
When running in verstage before bootblock, the PSP (ARM co-processor) is running with limited SRAM. It needs to stash the verstage console data internally until DRAM is brought up. Once DRAM is brought up the data is stashed in a "transfer buffer" region. In the current design, we are using the same region for the transfer buffer and the preram_cbmem_console region. This has the following downsides: 1) The pre-x86 buffer needs to be large enough to hold all the verstage, bootblock and romstage console logs. 2) On AMD platforms, the PSP verstage is signed. Changing the size of preram_cbmem_console after the fact will result in a mismatch of the transfer buffer between verstage and bootblock. This CL adds a new method that allows SoC specific code to copy the CBMEM console in the transfer buffer to the active CBMEM console.

This has the advantage that CBFS routines which just look up a file to inspect its metadata (e.g. cbfs_get_size()) do not cause the file to be measured twice. It also removes the existing inefficiency that files are loaded twice when measurement is enabled (once to measure and then again when they are used). When CBFS verification is enabled and uses the same hash algorithm as the TPM, we are even able to only hash the file a single time and use the result for both purposes.

Generally, use of these should be discouraged because that tends to mean that the file needs to be looked up more than once, and cbfs_alloc() or cbfs_type_load() are usually the more efficient alternative... but sometimes they're unavoidable, so we might as well offer them. Also remove the <cbfs_private.h> header which had already become sort of unnecessary with previous changes. cbfs_boot_lookup() is now exported in <cbfs.h> for use in inlines, but should not be used directly by other files (and is prefixed with an underscore to highlight that).

2021-11-16lib/prog_loaders, soc/amd/: Make payload_preload use cbfs_preloadRaul E Rangel
Now that CBFS has this functionality built in, we no longer need to manually code it. payload_preload used to use the payload_preload_cache region to store the raw payload contents. This region was placed outside the firmware reserved region, so it was available for use by the OS. This was possible because the payload isn't loaded again on S3 resume. cbfs_preload only uses the cbfs_cache region. This region must be reserved because it gets used on the S3 resume path. Unfortunately this means that cbfs_cache must be increased to hold the payload. Cezanne is the only platform currently using payload_preload, and the size of cbfs_cache has already been adjusted. In the future we could look into adding an option to cbfs_preload that would allow it to use a different memory pool for the cache allocation.

2021-11-04lib/cbfs: Add cbfs_preload()Raul E Rangel
This API will hide all the complexity of preloading a CBFS file. It makes it so the callers simply specify the file to preload and CBFS takes care of the rest. It will start a new thread to read the file into the cbfs_cache. When the file is actually required (i.e., cbfs_load, etc) it will wait for the preload thread to complete (if it hasn't already) and perform verification/decompression using the preloaded buffer. This design allows decompression/verification to happen in the main BSP thread so that timestamps are correctly reflected.

There is no reason this needs to be done in asm. It also allows different stages to use threads. If threads are no used in a specific stage, the compiler will garbage collect the space.

2021-07-18lib/thread: Make thread_run not block the current stateRaul E Rangel
If a thread wants to block a state transition it can use thread_run_until. Otherwise just let the thread run. `thread_join` can be used to block on the thread. Boot states are also a ramstage concept. If we want to use this API in any other stage, we need a way of starting a thread without talking about stages.

2021-07-18lib/thread: Add thread_handleRaul E Rangel
The thread_handle can be used to wait for a thread to exit. I also added a return value to the thread function that will be stored on the handle after it completes. This makes it easy for the callers to check if the thread completed successfully or had an error. The thread_join method uses the handle to block until the thread completes.
