ufs: Drop dm.h header file

2020-08-04T02:19:54Z

This header file should not be included in other header files. Remove it and use a forward declaration instead. Also drop asm/io.h Signed-off-by: Simon Glass

dma-mapping: move dma_map_(un)single() to

2020-02-19T13:27:30Z

The implementation of dma_map_single() and dma_unmap_single() is exactly the same for all the architectures that support them. Factor them out to , and make all drivers to include instead of . If we need to differentiate them for some architectures, we can move the generic definitions to . Add some comments to the helpers. The concept is quite similar to the DMA-API of Linux kernel. Drivers are agnostic about what is going on behind the scene. Just call dma_map_single() before the DMA, and dma_unmap_single() after it. Signed-off-by: Masahiro Yamada

dm: core: Create a new header file for 'compat' features

2020-02-06T02:33:46Z

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.

dm: core: Require users of devres to include the header

2020-02-06T02:33:46Z

At present devres.h is included in all files that include dm.h but few make use of it. Also this pulls in linux/compat which adds several more headers. Drop the automatic inclusion and require files to include devres themselves. This provides a good indication of which files use devres. Signed-off-by: Simon Glass Reviewed-by: Anatolij Gustschin

ufs: Add Initial Support for UFS subsystem

2019-10-24T00:47:12Z

Add Support for UFS Host Controller Interface (UFSHCI) for communicating with Universal Flash Storage (UFS) devices. The steps to initialize the host controller interface are the following: - Initiate the Host Controller Initialization process by writing to the Host controller enable register. - Configure the Host Controller base address registers by allocating a host memory space and related data structures. - Unipro link startup procedure - Check for connected device - Configure UFS host controller to process requests Also register this host controller as a SCSI host controller. Taken from Linux Kernel v5.2 (drivers/scsi/ufs/ufshcd.c) and ported to U-boot. Signed-off-by: Faiz Abbas
