Add support for the new DMA2D features to the STM32F429i-Disco LTDC configuration. From Marco Krahl.

Defines a second interface for the dma2d controller. Controlling both LTDC and DMA2D was unpractical from the programmers view because both controllers are to different. LTDC only controls the display visibility but the DMA2D controller changes the content of the frame buffer (buffer of the layer).
...
The main features are:
1. DMA2D interface
Supports the nuttx pixel formats:
- FB_FMT_RGB8
- FB_FMT_RGB24
- FB_FMT_RGB16_565
Dynamic layer allocation during runtime for the supported formats
- The number of allocatable layer can be configured.
Supported dma2d operation:
- blit (Copy content from source to destination layer) also works with
selectable area.
- blend (Blend two layer and copy the result to a destination layer wich can
be a third layer or one of the source layer) also works with selectable
area.
- fillarea (Fill a defined area of the whole layer with a specific color)
As a result of that the dma2d controller can't transfer data from the core coupled memory, CCM is disabled but usable by the ccm allocator. Currently the ccm allocator is used for allocating the layer structurei only. For the dma memory (layers frame buffer) memory is allocated from heap 2 and 3.
2. LTDC interface
I have changed the api for the currently non implemented operations:
- blit (Copy content from a dma2d layer to an ltdc layer) also works with
selectable area.
- blend (Blend two dma2d layer and copy the result to a destination ltdc
layer) also works with selectable area.
Note! ltdc layer is a layer referenced by the ltdc interface. dma2d layer
is a layer referenced by the dma2d interface.
One of the most important questions for me was, How can i flexible use an
ltdc layer with the dma2d interface, e.g. as source layer for dma2d
operations?
Get the layer id of the related dma2d layer by a special flag when using
getlid() function of the ltdc interface and use the layer id to reference
the specific dma2d layer by the dma2d interface.
The ltdc coupled dma2d layers are predefined and can't be dynamically
allocated of freed. They use the same frame buffer memory and the same
color lookup table.
Changes:
- layer internal format of the clut table
- interrupt handling for register reload (vertical vblank) instead using
waiting loop
- small fixes and refactoring
From Marco Krahl.

SAM3/4 and SAMV7 Serial: Serial interrupts left disabled.
...
A side-effect of changing serial settings via TERMIOS (such as tcsetattr) is that serial interrupts were being left disabled. This is not a problem if the serial configuration is changed when there are no open references to the serial device. In that case, serial interrupts are disabled and will not be enabled enabled until the serial device is first opened. But it is fatal if the serial device is already opened and if there is a task waiting to receive data. In that case, the side-effect of disabling interrupts is fatal: That task is then left hanging with interrupts disabled.

The STM32F4Discovery board doesn't come with a Low speed external oscillator so the default LSE source for the RTC doesn't work.
...
In stm32_rtcc.c the up_rtcinitialize() logic doesn't work with the LSI. The check on RTC_MAGIC on the BK0R register lead to rtc_setup() call that rightfully enables the lsi clock; but the next times, when the rtc is already setup, the rtc_resume() call does NOT start the lsi clock!
The right place to put LSE/LSI initialisation is inside stm32_stdclockconfig() in stm32fxxxxx_rcc.c. Doing this I checked the possible uses of the LSI and the LSE sources: the LSI can be used for RTC and/or the IWDG, while the LSE only for the RTC (and to output the MCO1 pin)..
This change is not verifed for any other platforms.

Cortex-M7: Add support for enabled the D-Cache in write only mode.
...
SAMV7 Ethernet: I- and D-Cache are now enabled in the netnsh/ configuration. D-Cache is enabled in write-though mode. This mode is necessary because the DMA descriptors are each 8-bytes in size but the D-Cache cache line is 32-bits in size. So it is impossible make coherency for every 8-byte DMA descriptor without write-through.

instead of Kconfig to help reduce bloat and confusion.
- Timer changed to remove ADC coupling in Kconfig to code and moved
configuration up from arch/arm/src/tiva to configs/tm4c123g-launchpad/src.
- GPIO driver needed small fixes in the configuration routines and
discovered false-positive bugs in interrupt testing: interrupts are now
verified to actually be working reliably.
- Attempt to apply some consistency in the tiva arch/ level's interface
to the config/board/ level driver configuration.

Big, very risky change: Remove all occurrences of up_maskack_irq() that disable and enable interrupts with up_ack_irq() that only acknowledges the interrupts. This is only used in interrupt decoding logic. Also remove the logic that unconditionally re-enables interrupts with the interrupt exits. This interferes with the drivers ability to control the interrupt state. This is a necessary, sweeping, global change and unfortunately impossible to test.

Removed setting of the initial timer interval load value (or, rather, it is always set to zero for a free-running timer). Also, do not unconditional enable the timer out interrupt. The timerout interrupt is not not enabled until tiva_timer32_setinterval() is called.

MMCSD SDIO: Add support for a new SDWAIT_WRCOMPLETE condition. The previous logic used a busy-wait loop to pool the card R1 start to determine when the card was ready for the next transfer. That busy-wait can be quite long -- hundreds of milliseconds. And alternative is to look the the SD D0 pin which will change state when the card is no longer busy.
...
This logic implements a change the avoids the busy-wait poll by reconfiguring the SD D0 pin as a GPIO interrupt, then waiting for the card to becom ready without taking up CPU cycles.
This change is conditioned on CONFIG_MMCSD_SDIOWATI_WRCOMPLETE and is currenlty only implemented for the STM32 SDIO driver.

stm32: implements ltdc frambuffer and support for ltdc layer operation
...
This implements the framebuffer support for the generic nuttx framebuffer
interface, (see nuttx/video/fb.h)
This also implements the interface to perform hardware accelerated layer
operation by the ltdc controller and dma2d controller later (see
nuttx/video/ltdc.h).
The following methods are supported by the ltdc interface:
- getvideoinfo
Get video information of the layer
- getplaneinfo
Get plane information of the layer
- getlid
Handle specific layer identifier. This allows to detect to current layer
state (e.g. important for layer flipping)
- setclut
Set the layer color lookup table. Up to 256 color entries supported.
- getclut
Get the layer color lookup table
- setcolor
Set the default layer color. In the context of the ltdc layer this means set
the default color outside the active area or if the layer is disabled.
- getcolor
Get the default layer color
- setcolorkey
Set the layer colorkey (chromakey). Colorkey is enabled by blendmode
LTDC_BLEND_COLORKEY
- getcolorkey
Get the layer colorkey
- setalpha
Set the constant alpha value. If blend mode LTDC_BLEND_SRCPIXELALPHA or
LTDC_BLEND_DESTPIXELALPHA is defined than the blended color is calculated
by the formel:
Cdest = Pixelalpha * Constalpha * Csrc.
Otherwise:
Cest = Constalpha * Csrc
- getalpha
get the alpha value
- setblendmode
Set the layer blendmode.
Supported blendmodes:
non blendmode (do not perform blend operation independent on the layers
alpha and colorkey)
alpha alpha blending (transparency)
destpixelalpha use pixel alpha value for the top layer (Layer2)
srcpixelalpha use pixel alpha value for the subjacent layer (Layer1)
colorkey enable colorkey
- getblendmode
Get the layer blendmode
- setarea
Set the active layer area, the visible rectangle inside the whole layer.
This also allows to change the position of the whole layer which is visible in
the selected area independent on the area position.
- getarea
Get the active layer area
- update
Reload the layer shadow register and make changes visible. Also supports
layer flipping.
Note! Dithering and background color are static parameter and can only changed
at build time.
Implementation details:
The implementation of ltdc interface was inspired by SDL and DirectFB.
All layer settings are shadowed before they become active (except setclut).
They are still inactive until the layer is updated. This is done by the update
method. Should clut only active after an update or not? Clut is used for drawing
while the other settings usually used for blend or blit operations. So i think
this should be the right way.

operation while the other settings usually used for blend or blit operations.
So i think this should be the right way.
Deviations from the ltdc hardware implementation:
- Shadow register update of both layer (Layer1 or Layer2) is independent as long
LTDC_UPDATE_SIM is not set. This flag allows to update both layer simultaneous.
Otherwise only the desired layer is updated.
Layer operation:
Keep in mind, both layer are allways active (of course if both enabled by the
configuration). First the Layer 1 is blended with the background color and the
result is blended with the Layer2. To avoid blend effects, set the Layer2 in non
blend mode. This is equal to blend with alpha = 255. Enable blending of Layer2
with the background color by enable blending of Layer1 and disable the opacity
by setting the alpha value to 0.
Layer flip:
A layer flip usual mean swapping two framebuffer. So the current inactive buffer
can refreshed with data while the active framebuffer is visible. A flip
operation changes the inactive layer to the active one and vice versa.
The ltdc implementation supports layer flip. This can be done by the update call
and the flag LTDC_UPDATE_FLIP. In this case ltdc makes the inactive layer
invisible. In detail, the inactive layer is disabled and the blendmode reset.
Detection of the current layer state (e.g. active or inactive) is supported
by the getlid method combined with one of the LTDC_LAYER_* flags.
Maybe an additional method "flip" for flip operation should be added to the ltdc
interface? But this make no sence from my view if the layer is a non LTDC layer,
e.g. playing with dma2d only.
Supported and tested nuttx pixel formats:
Single Layer without LTDC interface support:
- FB_FMT_RGB8 (cmap support required)
- FB_FMT_RGB16_565
- FB_FMT_RGB24
Single Layer with LTDC interface support:
- FB_FMT_RGB8 (cmap support required)
- FB_FMT_RGB16_565
- FB_FMT_RGB24
Dual Layer with LTDC interface support:
- FB_FMT_RGB8 (cmap support required)
- FB_FMT_RGB16_565
- FB_FMT_RGB24
Why is FB_FMT_ARGB8888 missing?
Changes:
- Remove unused register debug method.
Todo:
- Add support for backlight, currently not neccessary
Did i forgot something? Take a look in the ltdc example or the interface
description (see nuttx/include/video/ltdc.h).
Thanks to Ken for the base layout. ;)
