* filetype: add STM32 image typeAhmad Fatoum2019-07-151-0/+9
| | | | | | | | | | | | Both STM32MP BootROM and TF-A first stage expect subsequent bootloader stages to feature a specific 256-byte long STM32 file header. Add detection of the header to file_detect_type(). While there's only one version of the header so far, identify the new header as v1 anyway, so new versions can be unambiguously added.

| | | | | | | | | | | | | | | | | | The STM32MP1 can report brown out as reason for a reset, which doesn't fit into existing reasons. Thus add a new one to the enumeration. Signed-off-by: Ahmad Fatoum <a.fatoum@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | pstore: Only capture log messagesSascha Hauer2019-07-091-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this pstore only captures barebox log messages printed with pr_* and dev_*, but no longer anything printed with printf and friends. When capturing the barebox output with pstore only the log messages are of interest, but not the ones printed with printf and certainly not the things typed interactively on the command line. These are logged currently because we register pstore as a barebox console. Instead, hook into pr_puts which only outputs the barebox log messages.

* | | blspec: invalidate only necessary bootm variablesRouven Czerwinski2019-07-041-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of removing all global bootm variables, remove only the ones which will be set by the blspec entries. This allows setting the bootm.tee variable to load OP-TEE for blspec entries or setting the image load address.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The autoboot countdown is part of the init function. This patch factors out this code to a separate function to allow boards to call it at a different time.

* | startup: execute /env/bin/init as part of the initial shellIan Abbott2019-06-131-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 90df2a955e3c ("defaultenv: Convert init script to C") unintentionally changed the way the legacy "/env/bin/init" script is run, so that it runs in a sub-shell context, effectively changing `run_command("source /env/bin/init");` to `run_command("/env/bin/init");`. Therefore, any changes to shell environment variables made by the script are undone when the script exits. This patch reverts back to the old behavior.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is in line with other platforms such as i.MX, which allow specifying a debug port. As we can't use port indices because the UARTs aren't mapped consecutively, allow specifying a hex base at configuration time. A side effect of this patch is that sama5d4's HAVE_AT91_DBGU2 is now honored as well. Previously anything besides DBGU0 defaulted to DBGU1.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds initial support for OP-TEE, see https://www.op-tee.org/ barebox starts in secure mode as usual. When booting a kernel the bootm code also loads the optee_os binary. Instead of jumping into the kernel barebox jumps into the optee_os binary and puts the kernel execution address into the lr register. OP-TEE then jumps into the kernel in nonsecure mode. The optee_os binary is passed with the -t option to bootm or with global.bootm.tee. Optionally OP-TEE can be compiled into barebox using the builtin firmware feature. Enable the Kconfig option and place or link your tee binary as optee.bin into the firmware directory. The amount of SDRAM which is kept free for OP-TEE is configurable. This patch was tested on a i.MX6 Nitrogen6x board.

* | console: forbid ctrlc during startupSascha Hauer2019-04-241-0/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When global.autoboot_abort_key is set to ctrl-c then the user is expected to press ctrl-c to get to the prompt. The user might press ctrl-c before the init script runs the "timeout" command. In this case the init script is aborted at arbitrary places which leads to inconsistent results depending on the place it is aborted. This patch introduces the global.console.ctrlc_allowed variable. When this variable is set to false ctrl-c is ignored entirely. The variable is set to false by default and changed to true in the init script. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

|/ | | | | | | | | | | | | | | | | | It's easy to get stuck in an infinite loop in the hush shell: while true; do sleep 1; done The 'sleep' command will check for ctrl-c with the ctrlc() function. This will abort the sleep command. Hush then checks for ctrl-c again in the loop. The ctrl-c in the buffer has already been eaten by the sleep command, so the loop will continue. With this patch we remember the presence of a ctrl-c character in a variable instead of checking for a new character each time. The variable must be resetted explicitly by calling ctrlc_handled() which will be called by the shell in the outer loop. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
