The caculation of left space for version string is not correct, should
use VIDEO_COLS not VIDEO_LINE_LEN / 2, otherwise we will get larger space
than actual have and cause string to overlay logo picture.
Also current version string display only supports two lines words at max.
This also causes overlay when the LCD pixel colume size is not enough.

Support EPDC.
E-Ink feature is supported by i.MX6DL/SL and i.MX7D.
For now this driver only supports i.MX6DL/SL, because the
i.MX7D EPDC driver needs pxp support which is not included
in U-Boot.
Support user defined logo file, if there is no logo file, it will
draw a black border around a white screen.
If need to enable EPDC, a waveform file is required to let all
work.
Since we need LCD_MONOCHROME mode for EPDC, we introduce LCD_MONOCHROME
support.

As the HDMI splash screen feature is not well supported,
we should not set it to be the default display. In case,
users leave the 'panel' uboot environment variable empty
and connect the board with a HDMI monitor, the HDMI detect
funtion will work and enable the HDMI splash screen. So,
this patch disables HDMI detect function so that users
may only explicitly set the 'panel' variable to be 'HDMI'
to use HDMI splash screen.

The list_first_entry always assumes the list is not empty, it won't return NULL pointer when
the list is empty. So the "if (pdesc == NULL)" becomes a dead code. Fix the issue by calling
the list_empty before the list_first_entry.

The cod change updated the NAND driver BCH ECC layout algorithm to
support large oob size NAND chips(oob > 1024 bytes).
Current implementation requires each chunk size larger than oob size so
the bad block marker (BBM) can be guaranteed located in data chunk. The
ECC layout always using the unbalanced layout(Ecc for both meta and
Data0 chunk), but for the NAND chips with oob larger than 1k, the driver
cannot support because BCH doesn’t support GF 15 for 2K chunk.
The change keeps the data chunk no larger than 1k and adjust the ECC
strength or ECC layout to locate the BBM in data chunk. General idea for
large oob NAND chips is
1.Try all ECC strength from the minimum value required by NAND spec to
the maximum one that works, any ECC makes the BBM locate in data chunk
can be chosen.
2.If none of them works, using separate ECC for meta, which will add one
extra ecc with the same ECC strength as other data chunks. This extra
ECC can guarantee BBM located in data chunk, of course, we need to check
if oob can afford it.

For GPIO group which shared by multiple masters, it may set in RDC
to shared and semaphore required. Before access the GPIO register,
the GPIO driver must get the RDC semaphore, and release the semaphore
after the GPIO register access.

This patch is to support Bus Encryption Engine(BEE) for i.MX 6UL.
Supported feature:
1. SNVS key and soft key
2. CTR and ECB mode
3. Specify address region to bee.
Two commands are included:
bee init [key] [mode] [start] [end] - BEE block initial
"Example: bee init 1 1 0x80000000 0x80010000\n"
bee test [region]
"Example: bee test 1\n"
Mapping:
[0x10000000 - (0x10000000 + size - 1)] : [start - (start + size - 1)]
[0x30000000 - (0x30000000 + IRAM_SIZE - 1)] : [IRAM_BASE_ADDR -
(IRAM_BASE_ADDR + IRAM_SIZE - 1)]
Whatever start is, start - (start + size -1) will be fixed mapping to
0x10000000 - (0x10000000 + size - 1)
Since default AES region's protected size is SZ_512M, so
on mx6ul evk board, you can not simply run 'bee init', it will
overlap with uboot execution environment, you can use
'bee init 0 0 0x80000000 0x81000000'.
If want to use bee, Need to define CONFIG_CMD_BEE in board configuration
header file, since CONFIG_CMD_BEE default is not enabled.
