Commit 35c204d8a9d0 ("nand: reinstate lazy bad block scanning")
introduced lazy BBT scanning. However, some controller do parts
of the initialization (mxs_nand.c) during scan_bbt, hence for
those controllers the BBT must be scanned at initialization time.

While trying to display a BMP image by running the command
'bmp display <address>' the Colibri T30 was getting stuck (while on
iMX6, iMX7 and Vybrid it worked). After investigation on what was going
wrong, I noticed that the function 'lcd_set_cmap' should get a pointer
address for the cmap variable, but the function returned 00000000.
After further investigation, I noticed that this value should be held
in the structure.member 'panel_info.cmap', which memory was being
dynamically allocated in the function 'lcd_ctrl_init' of the file
'drivers/video/sandbox_sdl.c' (which was not being called). After
copying the allocation to the same function in the file
'drivers/video/tegra.c', the command 'bmp display' didn't break
anymore. The Colibri T20 module was working without the patch, as the
module does have valid memory at the address 0, and of course it kept
working after the patch now properly allocating memory for it.

Add board_usb_phy_mode weak function on similar lines to ehci-mx6.
However since Vybrid USB does not have a true OTG, make this weak
functon just return 0. The function is supposed to be implemented
by the individual boards using a GPIO for providing the OTG pin
functionality.

For mx7 the code needn't make provisions, we can use the simple
variant of fuse_bank_physical. Also U-Boot does not allow multi-

The ci_udc driver tries to use the ULPI interface for the USB OTG controller,
but this type is not supported by all i.MX6 and i.MX7 platforms. When setting to
ULPI, other platforms except the 6UL refuse the settings and keep default value.
But on 6UL, the PTW bit of PORTSC1 register which is documented as RO can change.
This cause the interface setting problem with USB PHY.
Fix the issue by removing the ULPI setting for i.MX6 and i.MX7. All will use default
UTMI setting.

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.

2. The image should be named epdc_logo.pgm.
3. If no epdc_logo.pgm found in the first partition(FAT), will choose

4. Default configuration is to draw image at pos (0,0). If 'splashpos'
env is set, will choose the pos from 'splashpos'.
5. The image size should not be bigger than screen total pixel size.
6. Implement board_setup_logo_file in board/freescale/common/epdc_setup.c
7. Introudce function prototype for board_setup_logo_file.

There is a hole in shadow registers address map of size 0x100
between bank 5 and bank 6 on iMX6QP, iMX6DQ, iMX6SDL, iMX6SX and iMX6UL.
Bank 5 ends at 0x6F0 and Bank 6 starts at 0x800. When reading the fuses,
we should account for this hole in address space.
Similar hole exists between bank 14 and bank 15 of size
0x80 on iMX6QP, iMX6DQ, iMX6SDL and iMX6SX.
Note: iMX6SL has only 0-7 banks and there is no hole.
Note: iMX6UL doesn't have this one.
When reading, we use register offset, so need to account for holes
to get the correct address.
When writing, we use bank/word index, there is no need to account
for holes, always use bank/word index from fuse map.

From IC guys:
"
After a thorough accuracy study of the Temp sense circuit,
we found that with our current equation, an average part can
read 7 degrees lower than a known forced temperature.
We also found out that the standard variance was around 2C;
which is the tightest distribution that we could create.
We need to change the temp sense equation to center the average
part around the target temperature.
Old Equation:
Temp = Troom,cal – slope*(Count measured – Count room fuse)
Where
Troom,cal = 25C and
Slope = 0.4297157 – (0.0015974 * Count room fuse)
New Equation:
Temp = Troom,cal – slope*(Count measured – Count room fuse) +offset
Where
Troom,cal = 25C and
Slope = 0.4445388 – (0.0016549 * Count room fuse)
Offset = 3.580661
"
According the new equation, update the thermal driver.

This patch is to add atmel AT45DB021E spi flash support.
Since this flash is different from the spi flash that we previous use such
as m25p32 and spanion spi nor flashes, pieces of code are added.
1.
The default page size is 264 bytes, but the mtd/spi framework can not
handle such page. So we need to configure the page size from 264 to 256 bytes.
Page Size command seq
“Power of 2” binary page size (256 bytes)| 3Dh 2Ah 80h A6h
DataFlash page size (264 bytes) | 3Dh 2Ah 80h A7h
And when probe the flash, configure the flash to 256 bytes page size, if
the page size is already 256bytes, just return and do not configure it again.
The page size configuration times is only about 10000, so to avoid configuring
it each time.
2.
Add the flash params in sf_params.c.
3.
This flash support 2K block erase, add this flag.
4.
The status command is 0xD7, different from others. It's polling status
bit is Bit 7
-> 0 Device is busy with an internal operation.
-> 1 Device is ready.
This patch has been tested on mx7d 19x19 ddr3 arm2 board. And tested
on mx7d 12x12 lpddr3 board. All works fine.
Note:
Since this flash is only 256KB, we can not test spi boot on mx7d 19x19 arm2
board. If want to test this flash, open CONFIG_SYS_USE_SPINOR.

Need to check value of spi_setup_slave and spi_setup_slave_fdt.
If their return value 'bus' is NULL, there is no need to pass it

If 'bus' is null, the original function flow is as following:
spi_flash_probe
|->spi_setup_slave
|->spi_probe_bus_tail
|->spi_flash_probe_slave
|->spi_free_slave
Alougth check the pointer in spi_free_slave is ok, checking the return value
of spi_setup_slave and spi_setup_slave_fdt is better.
