by another company and is no longer contracted to maintain the platform.

With commit 5663b137e682 ("arm: Remove edminiv2 board") the last
ARCH_ORION5X platform was removed. Remove the rest of the architecture
code which is now unused.

Failing to enable clocks will lead to bus hangs and the board crashing
in some cases, let's actually deal with this error and fail probe rather than hoping the clocks are already enabled.

As seen by a number of patches fixing memory leaks, U-Boot has a problem
with developer expectations around devm_kmalloc and friends. Namely,
whereas in Linux these memory allocations will be freed automatically in
most cases, in U-Boot this is only true if DEVRES is enabled. Now,
intentionally, in xPL phases, we do not (and do not offer as an option)
enabling DEVRES. However in full U-Boot this is left either to the user,
or some drivers have select'd DEVRES on their own. This inconsistency is
a problem. This series goes and deals with two small issues that were
shown by having all drivers that use devm_.alloc to allocate memory also
select DEVRES and then we make DEVRES no longer be a prompted option and
instead select'd as needed. We do not make this unconditional as it
would result in growing the resulting binary on the many platforms which
have no users of the devm_.alloc family of functions.

The devm alloc functions that we have may follow the Linux kernel model
where allocations are (almost always) automatically free()'d. However,
quite often we don't enable, in full U-Boot, the tracking and free()'ing
functionality. This in turn leads to memory leaks because the driver
author expects that since the functions have the same name as in the
Linux Kernel they have the same behavior. In turn we then get
functionally correct commits such as commit 00e1fed93c8c ("firmware:
ti_sci: Fix memory leaks in devm_ti_sci_get_of_resource") that manually
add these calls. Rather than manually tracking allocations and
implementing free()s, rework things so that we follow expectations by
enabling the DEVRES functionality (outside of xPL phases).

This turns DEVRES from a prompted symbol to a symbol that must be
select'd, and we now remove our non-managed alloc/free functions from
outside of xPL builds.

Exynos7 (and later) HS-I2C blocks have special interrupts regarding
various data transfer states (see HSI2C_INT_I2C_TRANS_EN). Add support
for enabling and handling these interrupt bits.

Add the corresponding compatible, 'samsung,exynos7-hsi2c'. In order to
differentiate between the multiple device variants, an enum is
introduced which is used where difference in implementations exist.

If CONFIG_OF_PLATDATA=y , then the udevice has no valid OF node associated
with it and ofnode_valid(node) evaluates to 0. The dev_read_u32_default()
call ultimately reaches ofnode_read_u32_index() which invokes fdt_getprop()
and passes result of ofnode_to_offset(node) as an offset parameter into it.

The ofnode_to_offset(node) returns -1 for invalid node, which leads to an
fdt_getprop(..., -1, ...) invocation, which will crash sandbox with SIGSEGV
because libfdt can not handle negative node offsets without full tree check,
which U-Boot inhibits to keep size lower.

Since i2c_child_post_bind() already calls dev_has_ofnode(dev), reuse the
same call and assign i2c->speed_hz = I2C_SPEED_STANDARD_RATE in case the
device has no valid node associated with it, and do not call any of the
dev_read_*() functions for devices without valid nodes.

The i2c_chip_of_to_plat() is called only from i2c_child_post_bind(),
inline i2c_chip_of_to_plat() into i2c_child_post_bind(). Drop the
if CONFIG_IS_ENABLED(OF_REAL) and depend on if (!dev_has_ofnode(dev))
which does check CONFIG_IS_ENABLED(OF_REAL) internally too.

Add a timeout mechanism when waiting for the RXDV (Receive Data
Valid) status bit to be set before reading data from the FIFO.
This prevents infinite polling loops that could occur if the
hardware doesn't respond as expected.

The timeout is set to 1000ms (CDNS_I2C_RXDV_TIMEOUT_MS) and uses
the wait_for_bit_le32() function to poll the status register. If
the timeout expires, an error code is returned.
