sunxi: video: Convert lcdc to use struct display_timing
Video driver for older Allwinner SoCs uses cfb console framework which
in turn uses struct ctfb_res_modes to hold timing informations. However,
DM video framework uses different structure - struct display_timing.
It makes more sense to convert lcdc to use new timing structure because
all new drivers should use DM video framework and older drivers might be
rewritten to use new framework too.

rockchip: rk3399: spl: add UART0 support for SPL
The RK3399-Q7 ("Puma") SoM exposes UART0 as the Qseven UART (i.e. the
serial line available via standardised pins on the edge connector and
available on a RS232 connector).
To support boards (such as the RK3399-Q7) that require UART0 as a
debug console, we match CONFIG_DEBUG_UART_BASE and add the appropriate
iomux setup to the rk3399 SPL code.
As we are already touching this code, we also move the board-specific
UART setup (i.e. iomux setup) into board_debug_uart_init(). This will
be called from the debug UART init when CONFIG_DEBUG_UART_BOARD_INIT
is set.
As the RK3399 needs to use its board_debug_uart_init() function, we
have Kconfig enable it by default for RK3399 builds.
With everything set up to define CONFIG_BAUDRATE via defconfig and
with to have the SPL debug UART either on UART0 or UART2, the configs
for the RK3399 EVB are then update (the change for the RK3399-Q7 is
left for later to not cause issues on applying the change).

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.

* The invocation cast the address to 'long'.
