2020-08-03efi: Tidy up header includesSimon Glass
Two files relies on efi_driver.h to include common.h and dm.h which is incorrect. The former should always be included in a non-host C file and the latter should be included if driver model is used. Signed-off-by: Simon Glass <sjg@chromium.org>

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass
At present dm/device.h includes the linux-compatible features. This requires including linux/compat.h which in turn includes a lot of headers. One of these is malloc.h which we thus end up including in every file in U-Boot. Apart from the inefficiency of this, it is problematic for sandbox which needs to use the system malloc() in some files. Move the compatibility features into a separate header file.

2020-01-15efi_driver: debug output efi_uc_start, efi_uc_stopHeinrich Schuchardt
Use the correct printf codes for the debug output in efi_uc_start() and efi_uc_stop(). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2020-01-15efi_driver: fix efi_uc_stop()Heinrich Schuchardt
Use the correct protocol in efi_uc_stop() when detaching the driver from the controller. Change the block IO unit test for the block device driver to throw an error instead of a todo if teardown fails. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>

Use Sphinx style comments for describing function parameters. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-04-12efi_loader: move efi_save_gd() call to board_r.cHeinrich Schuchardt
The first functions of the UEFI sub-system are invoked before reaching the U-Boot shell, e.g. efi_set_bootdev(), efi_dp_from_name(), efi_dp_from_file(). We should be able to print out device paths for debugging purposes here. When printing device paths via printf("%pD\n", dp) this invokes functions defined as EFIAPI. So efi_save_gd() must be called beforehand. So let's move the efi_save_gd() call to function initr_reloc_global_data(() in board_r.c. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
2019-02-13efi_driver: simplify error messageHeinrich Schuchardt
Stating the function module is sufficient. We don't need file and line number. Anyway the format code for the line number was incorrect (should be %d). Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-11-14blk: Call part_init() in the post_probe() methodBin Meng
part_init() is currently called in every DM BLK driver, either in its bind() or probe() method. However we can use the BLK uclass driver's post_probe() method to do it automatically. Update all DM BLK drivers to adopt this change. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-11-14efi_driver: blk: Switch to use platdata_auto_alloc_size for the driver dataBin Meng
Currently the efi block driver uses priv_auto_alloc_size for the driver data, however that's only available after the device probe phase. In order to make it accessible in an earlier phase, switch to use platdata_auto_alloc_size instead. This patch is the prerequisite for the follow up patch of DM BLK driver changes to work with EFI loader. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Set the DM_FLAG_NAME_ALLOCED flag to avoid a memory leak when the block device is removed. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Signed-off-by: Alexander Graf <agraf@suse.de>
2018-05-10SPDX: Convert a few files that were missed beforeTom Rini
As part of the main conversion a few files were missed. These files had additional whitespace after the '*' and before the SPDX tag and my previous regex was too strict. This time I did a grep for all SPDX tags and then filtered out anything that matched the correct styles. Fixes: 83d290c56fab ("SPDX: Convert all of our single license tags to Linux Kernel style") Reported-by: Heinrich Schuchardt <xypron.debian@gmx.de> Signed-off-by: Tom Rini <trini@konsulko.com>
2018-02-10efi_driver: return type of efi_driver_init()Heinrich Schuchardt
Change the return type of efi_driver_init() to efi_status_t. efi_driver_init() calls efi_add_driver() which returns an efi_status_t value. efi_driver_init() should not subject this value to a conversion to int losing high bits on 64bit systems.

2018-01-22efi_driver: EFI block driverHeinrich Schuchardt
This patch provides * a uclass for EFI drivers * a EFI driver for block devices For each EFI driver the uclass * creates a handle * adds the driver binding protocol The uclass provides the bind, start, and stop entry points for the driver binding protocol. In bind() and stop() it checks if the controller implements the protocol supported by the EFI driver. In the start() function it calls the bind() function of the EFI driver. In the stop() function it destroys the child controllers. The EFI block driver binds to controllers implementing the block io protocol. When the bind function of the EFI block driver is called it creates a new U-Boot block device. It installs child handles for all partitions and installs the simple file protocol on these. The read and write functions of the EFI block driver delegate calls to the controller that it is bound to. A usage example is as following: U-Boot loads the iPXE snp.efi executable. iPXE connects an iSCSI drive and exposes a handle with the block IO protocol. It calls ConnectController. Now the EFI block driver installs the partitions with the simple file protocol. iPXE uses the simple file protocol to load Grub or the Linux Kernel.
