usb: dwc3: gadget: make cache-maintenance on event buffers more robust
Merely using dma_alloc_coherent does not ensure that there is no stale
data left in the caches for the allocated DMA buffer (i.e. that the
affected cacheline may still be dirty).
The original code was doing the following (on AArch64, which
translates a 'flush' into a 'clean + invalidate'):
# during initialisation:
1. allocate buffers via memalign
=> buffers may still be modified (cached, dirty)
# during interrupt processing
2. clean + invalidate buffers
=> may commit stale data from a modified cacheline
3. read from buffers
This could lead to garbage info being written to buffers before
reading them during even-processing.
To make the event processing more robust, we use the following sequence
for the cache-maintenance:
# during initialisation:
1. allocate buffers via memalign
2. clean + invalidate buffers
(we only need the 'invalidate' part, but dwc3_flush_cache()
always performs a 'clean + invalidate')
# during interrupt processing
3. read the buffers
(we know these lines are not cached, due to the previous
invalidation and no other code touching them in-between)
4. clean + invalidate buffers
=> writes back any modification we may have made during event
processing and ensures that the lines are not in the cache
the next time we enter interrupt processing
Note that with the original sequence, we observe reproducible
(depending on the cache state: i.e. running dhcp/usb start before will
upset caches to get us around this) issues in the event processing (a
fatal synchronous abort in dwc3_gadget_uboot_handle_interrupt on the
first time interrupt handling is invoked) when running USB mass
storage emulation on our RK3399-Q7 with data-caches on.

ARM: at91: gpio: fix at91_set_gpio_value() define
When the CONFIG_ATMEL_LEGACY is undefined, according to the following
defines, at91_set_gpio_value() references to at91_set_pio_value(x, y)
with two parameters.
#define at91_set_gpio_value(x, y) at91_set_pio_value(x, y)
#define at91_get_gpio_value(x) at91_get_pio_value(x)
But there isn't the implementation of at91_set_pio_value(x, y) with
two parameters in U-Boot. This is an error.
Same as at91_get_gpio_value(x) define.

Not force to use python from PATH. Issue was noted when building with
Yocto, because python from the distro is always taken instead of
python-native built during Yocto process.

dm: core: Ensure DMA regions start up with the cache clean
There is a strange interaction with drivers which use DMA if the cache
starts off in a dirty state. Buffer space which the driver reads (but has
not previously written) can contain zero bytes from alloc_priv(). This can
cause corruption of the memory used by DMA for incoming data.
Fix this and add a comment to explain the problem.
This allows the dwc2 driver to work correctly with driver model, for
example.
core/uclass: Print name of device in uclass_find_device_by_seq()
uclass_find_device_by_seq() prints seq and req_seq when debugging is
enabled, but this information is not very useful by itself. Add the
name of he driver to this information. This improves debugging as it
shows which devices are being considered.

With Python 3.5.2 encode will throw an exception if val is a byte array.
Decode it to a string first. This assumes it's utf-8, if it's not valid
utf-8 it will throw an exception.

os.read() returns a byte array in Python 3.5.2 and needs to be converted
into a string. Check if the returned value is an instance of bytes and
if it is decode it as a utf-8 string. If it is not a utf-8 encoded string
the decoding may fail with an exception.
Prior to this fix the comparisions check data == "" would fail when data
was b'' and would cause an infinite memory leaking loop. joins would
also fail with an exception below but due to the infinite loop it never
made it that far.

serial: ns16550: Link in the DM driver when when using platdata
Do not condition the compilation of the U_BOOT_DRIVER by !OF_PLATDATA.
This is inconsistent with the majority of other drivers. This also
blocks OF_PLATDATA boards with an 16550-compatible serial from using
serial in SPL.
