common/console.c: prevent pre-console buffer contents from being added to itself

2022-08-31T16:16:01Z

I do not have any non-serial output devices, so a print_pre_console_buffer(PRE_CONSOLE_FLUSHPOINT2_EVERYTHING_BUT_SERIAL) does nothing for me. However, I was manually inspected the pre-console buffer using md.b, and I noticed that the early part of it was repeated. The reason is that the first call of print_pre_console_buffer(), from console_init_f(), ends up invoking puts() with the contents of the buffer at that point, and puts() at that point ends up in the else branch of if (gd->flags & GD_FLG_DEVINIT) { /* Send to the standard output */ fputs(stdout, s); } else { /* Send directly to the handler */ pre_console_puts(s); serial_puts(s); } so indeed the contents is added again. That can be somewhat confusing (both when reading the buffer manually, but also if it did actually come out on some device). So disable all use of the pre-console buffer while print_pre_console_buffer() is emitting it. Signed-off-by: Rasmus Villemoes Reviewed-by: Simon Glass

bootstage: Show func name for bootstage_mark/error

2022-08-21T00:07:32Z

bootstage_mark() and bootstate_error() are not recording any name and in report it is showing as id=. That's not useful and it is better to show function name which calls it. That's why use macros with passing __func__ as recorded name for bootstage. Origin report looks like this: ZynqMP> bootstage report Timer summary in microseconds (10 records): Mark Elapsed Stage 0 0 reset 2,482,383 2,482,383 board_init_f 4,278,821 1,796,438 board_init_r 4,825,331 546,510 id=64 4,858,409 33,078 id=65 4,862,382 3,973 main_loop 4,921,713 59,331 usb_start 9,345,345 4,423,632 id=175 When this patch is applied.

hwconfig: Allow to use restricted env

2022-08-20T22:12:51Z

During early boot phase GD_FLG_ENV_READY is not set but env_get() may work when env is ready in restricted mode. Do not fail with error message "WARNING: Calling __hwconfig without a buffer and before environment is ready" when env is already working by checking for ENV_VALID flag. Signed-off-by: Pali Rohár

event: Add an event for device tree fixups

2022-08-12T12:17:11Z

At present there is a confusing array of functions that handle the device tree fix-ups needed for booting an OS. We should be able to switch to using events to clean this up. As a first step, create a new event type and call it from the standard place. Note that this event uses the ofnode interface only, since this can support live tree which is more efficient when making lots of updates. Signed-off-by: Simon Glass

spl: opensbi: convert scratch options to config

Convert hardcoded "opensbi_info.options" to config provided value, this allows changing options passed to OpenSBI. SPL_OPENSBI_SCRATCH_OPTIONS is defaulted to SBI_SCRATCH_NO_BOOT_PRINTS.

Audit inclusion

2022-08-04T20:18:47Z

A large number of files include as it used to be how various SPI flash related functions were found, or for other reasons entirely. In order to migrate some further CONFIG symbols to Kconfig we need to not include flash.h in cases where we don't have a NOR flash of some sort enabled. Furthermore, in cases where we are in common code and it doesn't make sense to try and further refactor the code itself in to new files we need to guard this inclusion. Signed-off-by: Tom Rini

vpl: fix reference in comment to non-existing SPL_SERIAL_SUPPORT

2022-08-04T19:32:20Z

Since commit 2a7360666871 ("serial: Rename SERIAL_SUPPORT to SERIAL") SPL_SERIAL_SUPPORT is named SPL_SERIAL. So let's update the comment to point to the correct Kconfig option in the comment of VPL_SERIAL.

spl: mmc: Use correct MMC device when loading image

2022-08-04T17:59:59Z

When attempting to load images from multiple MMC devices in sequence, spl_mmc_load() chooses the wrong device from the second attempt onwards. The reason is that MMC initialization is only done on its first call and spl_mmc_load() will then continue using this same device for all future calls. Fix this by checking the devnum of the "cached" device struct against the one which is requested. If they match, use the cached one but if they do not match, initialize the new device. This fixes specifying multiple MMC devices in the SPL's boot order to fall back when U-Boot Proper is corrupted or missing on the first attempted MMC device.
