FALCO: stop using the slippy graphics code
It's time to start cleaning up the falco graphics code, but it needs to have its own files, not slippy's. Change-Id: I7dbe27eafbf247b5c7806819bf0059d8b10e842c Signed-off-by: Ronald G.

|
* Here is the rough outline of how we bring up the display:
|
||||||
|
* 1. Upon power-on Sink generates a hot plug detection pulse thru HPD
|
||||||
|
* 2. Source determines video mode by reading DPCD receiver capability field
|
||||||
|
* (DPCD 00000h to 0000Dh) including eDP CP capability register (DPCD
|
||||||
|
* 0000Dh).
|
||||||
|
* 3. Sink replies DPCD receiver capability field.
|
||||||
|
* 4. Source starts EDID read thru I2C-over-AUX.
|
||||||
|
* 5. Sink replies EDID thru I2C-over-AUX.
|
||||||
|
* 6. Source determines link configuration, such as MAX_LINK_RATE and
|
||||||
|
* MAX_LANE_COUNT. Source also determines which type of eDP Authentication
|
||||||
|
* method to use and writes DPCD link configuration field (DPCD 00100h to
|
||||||
|
* 0010Ah) including eDP configuration set (DPCD 0010Ah).
|
||||||
|
* 7. Source starts link training. Sink does clock recovery and equalization.
|
||||||
|
* 8. Source reads DPCD link status field (DPCD 00200h to 0020Bh).
|
||||||
|
* 9. Sink replies DPCD link status field. If main link is not stable, Source
|
||||||
|
* repeats Step 7.
|
||||||
|
* 10. Source sends MSA (Main Stream Attribute) data. Sink extracts video
|
||||||
|
* parameters and recovers stream clock.
|
||||||
|
* 11. Source sends video data.

/* how many bytes do we need for the framebuffer?
|

|
* Well, this gets messy. To get an exact answer, we have
|
||||||
|
* to ask the panel, but we'd rather zero the memory
|
||||||
|
* and set up the gtt while the panel powers up. So,
|
||||||
|
* we take a reasonable guess, secure in the knowledge that the
|
||||||
|
* MRC has to overestimate the number of bytes used.
|
||||||
|
* 8 MiB is a very safe guess. There may be a better way later, but
|
||||||
|
* fact is, the initial framebuffer is only very temporary. And taking
|
||||||
|
* a little long is ok; this is done much faster than the AUX
|

* memory addresses. As in the CPU, GTTs map 4K pages.
|
||||||
|
* The setgtt function adds a further bit of flexibility:
|
||||||
|
* it allows you to set a range (the first two parameters) to point
|

* to a physical address (third parameter);the physical address is

|
* the page takes a up to 200 ms.
