efi_driver: move event registration to driver

2022-10-06T20:54:58Z

Move the registration of events for the addition and removal of block devices to the block device driver. Here we can add a reference to the EFI Driver Binding protocol as context. Signed-off-by: Heinrich Schuchardt

efi_driver: add init function to EFI block driver

2022-10-06T20:54:58Z

For handling added and removed block devices we need to register events which has to be done when the driver is installed. This patch only creates an empty init function that will be filled with code later on. The function needs to be called before any EFI block devices are used. Move the efi_driver_init() call to early init. Signed-off-by: Heinrich Schuchardt

efi_driver: provide driver binding protocol to bind function

2022-10-06T20:54:57Z

DisconnectController() is based on the open protocol information created when the driver opens a protocol with BY_CHILD_CONTROLLER or BY_DRIVER. To create an open protocol information it is required to supply the handle of the driver as agent handle. This information is available as field DriverBindingHandle in the driver binding protocol.

efi_driver: carve out function to create block device

2022-10-06T20:54:57Z

* Carve out function efi_bl_create_block_device() from efi_bl_bind(). * Add a check for U-Boot devices to efi_bl_bind(). Signed-off-by: Heinrich Schuchardt

efi_driver: fix error handling

2022-10-06T20:54:57Z

If creating the block device fails, * delete all created objects and references * close the protocol interface on the controller Signed-off-by: Heinrich Schuchardt

blk: Switch over to using uclass IDs

2022-09-16T15:05:16Z

We currently have an if_type (interface type) and a uclass id. These are closely related and we don't need to have both. Drop the if_type values and use the uclass ones instead. Maintain the existing, subtle, one-way conversion between UCLASS_USB and UCLASS_MASS_STORAGE for now, and add a comment. Signed-off-by: Simon Glass

efi_loader: move udevice pointer into struct efi_object

2022-08-13T09:09:49Z

This is a preparation patch to provide the unified method to access udevice pointer associated with the EFI handle by adding udevice pointer into struct efi_object. The patch also introduces a helper function efi_link_dev() to link the udevice and EFI handle. The EFI handles of both EFI block io driver implemented in lib/efi_loader/efi_disk.c and EFI block io driver implemented as EFI payload can access the udevice pointer in the struct efi_object. We can use this udevice pointer to get the U-Boot friendly block device name(e.g. mmc 0:1, nvme 0:1) through EFI handle. Signed-off-by: Masahisa Kojima Reviewed-by: Heinrich Schuchardt

efi_loader: disk: a helper function to create efi_disk objects from udevice

2022-04-23T20:05:41Z

Add efi_disk_probe() function. This function creates an efi_disk object for a raw disk device (UCLASS_BLK) and additional objects for related partitions (UCLASS_PARTITION). So this function is expected to be called through driver model's "probe" interface every time one raw disk device is detected and activated. We assume that partition devices (UCLASS_PARTITION) have been created when this function is invoked. Signed-off-by: AKASHI Takahiro

efi: Rename UCLASS_EFI and IF_TYPE_EFI

2021-12-09T19:43:25Z

These names are better used for access to devices provided by an EFI layer. Use EFI_LOADER instead here, since these are only available in U-Boot's EFI_LOADER layer. Signed-off-by: Simon Glass Reviewed-by: Heinrich Schuchardt
