QSPI controller automatic enable the chipselect signal according the
dest AMBA memory address. Now we distribute the AMBA memory zone
averagely to every chipselect slave device according chipselect
numbers got from dts node.

The address value and size value get from dts "reg" property have
type of u64 on arm64. If we assign those values to "u32" variables,
driver can't work correctly. Converting the type of those variables
to fdt_xxx_t.

The initial training for the DDRC may provide results that are not
optimized. The workaround provides better read timing margins.

Add an emulation of an SD card to sandbox, allowing MMC to be used in tests.
The emulation is very simple, supporting only card detection and reading
test data.

Add support for enabling CONFIG_BLK with MMC. This involves changing a
few functions to use struct udevice and adding a MMC block device driver.
Signed-off-by: Simon Glass <[email protected]>
|
|
Binding an MMC device when CONFIG_BLK is enabled requires that a block
device be bound as a child of the MMC device. Add a function to do this.
The mmc_create() method will be used only when DM_BLK is disabled.
Add an unbind method also.

Implement the functions in mmc_legacy.c for driver-model block devices, so
that MMC can use driver model for these. This allows CONFIG_BLK to be enabled

Instead of looking up the MMC device by number, just pass it in. This makes

At present the MMC subsystem maintains its own list of MMC devices. This
cannot work with driver model, which needs to maintain this itself. Move the
list code into a separate 'legacy' file. The core MMC code remains, and will
be shared with the driver-model implementation.

The MMC block device is contained within struct mmc. But with driver model
this will not be the case. Add a function to obtain the block device. We

This function is defined after it is used. In preparation for making it

Mark the device name as allocated so that it will be freed correctly when the
device is unbound.
Signed-off-by: Simon Glass <[email protected]>

Some devices have a name that is stored in allocated memory. At present
there is no mechanism to free this memory when the device is unbound.
Add a device flag to track whether a name is allocated and a function to
add the flag. Free the memory when the device is unbound.

This started as 'ahci' and was renamed to 'disk' during code review. But it
seems that this is too generic. Now that we have a 'blk' uclass, we can use

Many drivers use a common form of offset + flags for device
tree nodes. e.g.:
<&gpio1 2 GPIO_ACTIVE_LOW>
This patch adds a common implementation of this type of parsing
and calls it when a gpio driver doesn't supply its' own xlate
routine.
This will allow removal of the driver-specific versions in a
handful of drivers and simplify the addition of new drivers.
