core: ofnode: add ofnode_get_parent function

2018-02-23T19:47:47+00:00

The Rockchip video drivers need to walk the ofnode-parrents to find
an enclosing device that has a UCLASS_DISPLAY driver bound.  This
adds a ofnode_get_parent()-function that returns the parent-node.

dm: core: Add a function to look up a uclass by name

2018-02-03T17:08:40+00:00

Each uclass has a driver name which we can use to look up the uclass. This
is useful for logging, where the uclass ID is used as the category.

Add a function to handle this, as well as a test.

serial: bcm283x_mu: Remove support for post-init disabling

2018-01-28T17:27:33+00:00

We are switching to a model where a serial device doesn't even get probed when
it's not muxed properly, so we don't need device specific disabling
functionality anymore.

efi_driver: EFI block driver

2018-01-22T22:09:14+00:00

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.

dm: add dev_read_u32()

2018-01-22T05:11:58+00:00

dev_read_u32_default() always returns something even when the property
is missing.  So, it is impossible to do nothing in the case.  One
solution is to use ofnode_read_u32() instead, but adding dev_read_u32()
will be helpful.

BTW, Linux has an equvalent function, device_property_read_u32();
it is clearer that it reads a property.  I cannot understand the
behavior of dev_read_u32() from its name.
