2020-08-14xen: pvblock: Add initial support for para-virtualized block driverAnastasiia Lukianenko1-0/+2
Add initial infrastructure for Xen para-virtualized block device. This includes compile-time configuration and the skeleton for the future driver implementation. Add new class UCLASS_PVBLOCK which is going to be a parent for virtual block devices. Add new interface type IF_TYPE_PVBLOCK. Implement basic driver setup by reading XenStore configuration.

2020-02-05dm: core: Create a new header file for 'compat' featuresSimon Glass2-0/+2
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.

2019-08-30Revert "blk: Invalidate block cache when switching hwpart"Weijie Gao1-12/+2
This reverts commit 0ebe112d09b48230ba4be833cd3504b06997d9a4. Most block devices have only one hwpart. Multiple hwparts only found used by eMMC devices in u-boot. The mmc driver do blk_dselect_hwpart() at the beginning of mmc_bread() which causes block cache being invalidated too frequently and makes block cache useless. So it's not a good idea to put blkcache_invalidate() in the common functions. It should be called inside mmc_select_hwpart().

2019-07-18blk: Invalidate block cache when switching hwpartWeijie Gao1-2/+12
Some storage devices have multiple hw partitions and both address from zero, for example eMMC. However currently block cache invalidation only applies to block write/erase. This can cause a problem that data of current hw partition is cached before switching to another hw partition. And the following read operation of the latter hw partition will get wrong data when reading from the addresses that have been cached previously. To solve this problem, invalidate block cache after a successful select_hwpart operation. Signed-off-by: Weijie Gao <weijie.gao@mediatek.com>

2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini6-13/+6
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

2018-01-22efi_driver: EFI block driverHeinrich Schuchardt1-1/+3
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.
