* efi_loader: correct EFI_BLOCK_IO_PROTOCOL definitionsHeinrich Schuchardt2018-01-221-4/+4
| | | | | | | | | | Add the revision constants. Depending on the revision additional fields are needed in the media descriptor. Use efi_uintn_t for number of bytes to read or write. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
* efi_loader: make efi_disk_create_partitions a global symbolHeinrich Schuchardt2018-01-221-24/+60
| | | | | | | | | | | | | | | Up to now we have been using efi_disk_create_partitions() to create partitions for block devices that existed before starting an EFI application. We need to call it for block devices created by EFI applications at run time. The EFI application will define the handle for the block device and install a device path protocol on it. We have to use this device path as stem for the partition device paths. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>

* efi_loader: allocate correct memory type for EFI imageHeinrich Schuchardt2018-01-221-24/+40
| | | | | | | | | | | The category of memory allocated for an EFI image should depend on its type (application, bootime service driver, runtime service driver).

| | | | | | | | | | | | | | For the construction of device paths we need to call the AllocatePool service. We should not ignore if it fails due to an out of memory situation. This patch changes the device path functions to return NULL if the memory allocation fails. Additional patches will be needed to fix the callers.

* vsprintf.c: add EFI device path printingHeinrich Schuchardt2018-01-221-6/+41
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For debugging efi_loader we need the capability to print EFI device paths. With this patch we can write: debug("device path: %pD", dp); A possible output would be device path: /MemoryMapped(0x0,0x3ff93a82,0x3ff93a82) This enhancement is not available when building without EFI support and neither in the SPL nor in the API example. A test is provided. It can be executed in the sandbox with command ut_print. The development for EFI support in the sandbox is currently in branch u-boot-dm/efi-working. The branch currently lacks commit 6ea8b580f06b ("efi_loader: correct DeviceNodeToText for media types"). Ater rebasing the aforementioned branch on U-Boot v2018.01 the test is executed successfully. Without EFI support in the sandbox the test is simply skipped.
