ec1add1e51 dm: core: Inline a few ofnode functions in SPL
A recent change to unify the flattree/livetree code introduced a small
size increase in SPL on some boards. For example SPL code size for
px30-core-ctouch2-px30 increased by 40 bytes.

To address this we can take advantage of the fact that some of the ofnode
functions are only called a few times in SPL, so it is worth inlining
them.

Add new Kconfig options to control this. These functions are not inlined
for U-Boot proper, since this increases code size.

Fixes: 2ebea5eaeb ("dm: core: Combine the flattree and livetree binding code")

73da3d2cff buildman: Remove output binaries before building
Buildman reuses build directories from previous builds to avoid the cost
of 'make mrproper' for every build. If the previous build produced an SPL
image but the current one does not, the SPL image will remain and buildman
will think it is a result of building the current board.

Remove these files before building, to avoid this problem.

fc314300dd dm: spi: Fix spi_free_slave() freed memory write
Remove setting slave->dev to NULL after the device_remove() call.

The slave pointer points to dev->parent_priv, which has already
been freed by device_free(), called from device_remove() in the
preceding line. Writing to slave->dev may cause corruption of the
dlmalloc free chunk forward pointer of the previously freed chunk.

a5624c6b4c test: dm: spi: Add testcase for spi_claim_bus()
Add testcase for spi_claim_bus(), which checks that sandbox spi bus
speed/mode settings are updated correctly when multiple slaves use
the bus consecutively. The following configurations are used for the
two spi slaves involved:
  * different max_hz / different modes
  * different max_hz / same modes
  * different modes / same max_hz

asm/test.h header is added in order to be able to retrieve the current
speed/mode of the sandbox spi bus, via sandbox_spi_get_{speed, mode}.

741280e9ac spi: spi-uclass: Fix spi_claim_bus() speed/mode setup logic
Currently, when different spi slaves claim the bus consecutively using
spi_claim_bus(), spi_set_speed_mode() will only be executed on the first
two calls, leaving the bus in a bad state starting with the third call.

This patch drops spi_slave->speed member and adds caching of bus
speed/mode in dm_spi_bus struct. It also updates spi_claim_bus() to call
spi_set_speed_mode() if either speed or mode is different from what the
bus is currently configured for. Current behavior is to only take into
account the speed, but not the mode, which seems wrong.

c589132a1d fdt: Use phandle to distinguish DT nodes with same name
While assigning the sequence number to subsystem instances by reading the
aliases property, only DT nodes names are compared and not the complete
path. This causes a problem when there are two DT nodes with same name but
have different paths.

In arch/arm/dts/k3-am65-main.dtsi there are two USB controllers with the
same device tree node name but different path. When aliases are defined for
these USB controllers then fdtdec_get_alias_seq() fails to pick the correct
instance for a given index.

fdt_path_offset() function is slow and this would effect the U-Boot
startup. To avert the time penalty on all boards, apply this extra check
only when required by using a config option.

Fix it by comparing the phandles of DT nodes after the node names match,
under a config option.

Use the new sequence number in all cases. Drop the logic to check for a
valid number in designware_i2c, since it will always be valid.

Also drop the numbering in the uclass, since we can rely on driver
model giving us the right sequence numbers.

5c58002255 octeon: Don't attempt to set the sequence number
Several Octeon drivers operate by setting the sequence number of their
device. This should not be needed with the new sequence number setup. Also
it is not permitted. Drop it.
