Currently devices on the virtio bus is not automatically enumerated, which means peripherals on the virtio bus are not discovered by their drivers. This uses board_init() to do the virtio enumeration. Signed-off-by: NBin Meng <bmeng.cn@gmail.com> Reviewed-by: NSimon Glass <sjg@chromium.org>

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.

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.

The blk_base test case creates a USB mass storage block device with the Sandbox host block device as its parent. This does not make any sense and causes potential issue, for example if the test case tries to read/write anything on the USB mass storage block device it will definitely fail as its parent is not on USB bus at all. Correct the test case by creating another Sandbox host block device instead of the USB mass storage one and adjust the case accordingly.

VirtIO can use various different buses and virtio devices are commonly implemented as PCI devices. But virtual environments without PCI support (a common situation in embedded devices models) might use simple memory mapped device (“virtio-mmio”) instead of the PCI device. This adds a transport driver that implements UCLASS_VIRTIO for virtio over mmio.

This adds a new virtio uclass driver for “virtio” [1] family of devices that are are found in virtual environments like QEMU, yet by design they look like physical devices to the guest. The uclass driver provides child_pre_probe() and child_post_probe() methods to do some common operations for virtio device drivers like device and driver supported feature negotiation, etc. [1] http://docs.oasis-open.org/virtio/virtio/v1.0/virtio-v1.0.pdfSigned-off-by: NTuomas Tynkkynen <tuomas.tynkkynen@iki.fi> Signed-off-by: NBin Meng <bmeng.cn@gmail.com> Reviewed-by: NSimon Glass <sjg@chromium.org>

It would be convenient if one could use the regmap API in conjunction with register maps defined as structs (i.e. structs that directly mirror the memory layout of the registers in question). A similar approach was planned with the regmap_write32/regmap_read32 macros, but was never used. Hence, implement regmap_set/regmap_range_set and regmap_get/regmap_range_get macros, which, given a register map, a struct describing the layout of the register map, and a member name automatically produce regmap_read/regmap_write calls that access the specified member in the register map.

It is useful to be able to treat the different ranges of a regmap separately to be able to use distinct offset for them, but this is currently not implemented in the regmap API. To preserve backwards compatibility, add regmap_read_range and regmap_write_range functions that take an additional parameter 'range_num' that identifies the range to operate on.

The regmap functions currently assume that all register map accesses have a data width of 32 bits, but there are maps that have different widths. To rectify this, implement the regmap_raw_read and regmap_raw_write functions from the Linux kernel API that specify the width of a desired read or write operation on a regmap. Implement the regmap_read and regmap_write functions using these raw functions in a backwards-compatible manner.

Commit f2006808: ("dm: core: parse chosen node") added a logic to parse the chosen node during dm_scan_fdt_node(), but unfortunately it missed adding the same logic in dm_scan_fdt_live(). This mirrors the logic in the livetree version. The weird thing is that commit f2006808 did update the test case to test such logic, but even if I reset to that commit, the test case still fails, and I have no idea how it could pass.
