| * i2c: stub device_i2c_driver if I2C is disabledMichael Tretter2022-01-031-0/+5
| | | | | | | | | | | | | | | | | | This allows drivers that support multiple buses to keep the code for registering their I2C variant even if I2C is disabled.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| * | serial: efi-stdio: move efi-stdio.h header to central locationAhmad Fatoum2021-11-251-0/+100
| | | | | | | | | | | | | | | | | | | | | | | | | | | EFI loader will provide simple text input/output protocols, so it makes sense to reuse the same definitions for both loader and payload.

| * | asm-generic: move sync_caches_for_execution declaration to <asm/cache.h>Ahmad Fatoum2021-11-251-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We have three architectures defining sync_caches_for_execution(). Have them all do so in a header of the same name to allow using it in common code later on, like in an EFI image loading routine.
