| * driver: implement dev_err_probe()Ahmad Fatoum2021-11-251-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | The function like it's Linux equivalent is meant to be used during driver probe whenever an error occurs that would lead to aborting the probe. This allows moving EPROBE_DEFER checks out of drivers and in future could allow selectively compiling out only error probe messages, as they are mainly interesting during bring up.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Board code may compute values for device tree properties and write them as strings. Make this easier by adding a of_property_write_string variant that does formatted output. This also saves an allocation, because asprintf buffer is reused.

| * | efi: add efi_device hook to be called before an image is startedSascha Hauer2021-12-131-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | boot_services::open_protocol supports opening protocols exclusively. A protocol that is opened exclusively can not be used anymore by an application that is called via boot_services::start_image. We want to open the SNP protocol exclusively in the next step. That would mean a chainloaded barebox could no longer use the SNP protocol because it's exclusively opened by the current barebox already. To work around this a efi_drv::dev_pause and efi_drv::dev_continue is introduced. The former is called before an application is started and the latter right after an application has exited. This will be used by the SNP network driver to enter/leave exclusive mode. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This is currently used on ARM and sandbox, but it's relevant for other platforms like x86 as well if driver code wants to make use of the functions defined within. MIPS and PowerPC already defines the symbols, but that's ok because <bitio.h> doesn't override existing macros. This works for MIPS, but not PowerPC, where those aren't macros. Fix that up.
