03544c6640 I2C: mxc_i2c: make I2C1 and I2C2 optional
The driver assumed that I2C1 and I2C2 were always enabled,
and if they were not, then an asynchronous abort was (silently)
raised, to be caught much later on in the Linux kernel.

Fix this by making I2C1 and I2C2 optional just like I2C3 and I2C4
are.

To make the change binary-invariant, declare I2C1 and I2C2 in
every include/configs/ file which defines CONFIG_SYS_I2C_MXC.

Also, while updating README about CONFIG_SYS_I2C_MXC_I2C1 and
CONFIG_SYS_I2C_MXC_I2C2, add missing descriptions for I2C4 speed
(CONFIG_SYS_MXC_I2C4_SPEED) and slave (CONFIG_SYS_MXC_I2C4_SLAVE)
config options.

cdbdde3f56 mx6qsabreauto: Add parallel NOR flash support
mx6sabreauto boards come with 32 MiB of parallel NOR flash.

Add support for it:

U-Boot 2015.01-rc1-18107-g1543636-dirty (Nov 14 2014 - 11:11:04)

Reset cause: POR
Board: MX6Q-Sabreauto revA
I2C:   ready
DRAM:  2 GiB
Flash: 32 MiB
NAND:  0 MiB

not used.

8fe280f330 imx: mx6 sabreauto: Add board support for USB EHCI
On mx6 sabreauto board, there are two USB ports:
0: OTG
1: HOST
The EHCI driver is enabled for this board, but the IOMUX and VBUS power
control is not implemented, which cause both USB port failed to work.
This patch fix the problem by adding the board support codes.

Since the power control uses the GPIO pin from port expander MAX7310,
the PCA953X driver is enabled for accessing the MAX7310.

The ID pin of OTG Port needs to configure the GPR1 bit 13 for selecting
its daisy chain. Add a new function "imx_iomux_set_gpr_register" to
handle GPR register setting.

19a895cbe9 mx6qsabreauto: Remove imx6q-sabreauto.dts
Commit fa9c021632 ("mx6: add example DTB for mx6qsabreauto") introduced
'imx6q-sabreauto.dts' but it adds no real value as the dts file only contains
the 'model' and 'compatible' strings.

After this commit the final binary is also changed from 'u-boot.imx' to
'u-boot-dtb.imx', which may confuse users.

So revert it until a more complete and useful device tree could be provided.

d1a5286099 usb: ehci-mx6: add support for otg port
Previously, only host1 was supported using an index of 0.
Now, otg has index 0, host1 is 1, host2 is 2, host3 is 3.
Since OTG requires usbmode to be set after reset, I added
CONFIG_EHCI_HCD_INIT_AFTER_RESET to nitrogen6x.h and
mx6qsabreauto.h.

I also added a weak function board_ehci_power to handle
turning power on/off for otg.

Type is type of device connected (USB stick vs Host.)
Init is type of device desired.
Only power up port if type == init == USB_INIT_HOST.
Only return error if type != init.

7fb72c7979 ARM: imx: Fix incorrect usage of CONFIG_SYS_MMC_ENV_PART
When running the "save" command several times on a mx6qsabresd we see:

U-Boot > save
Saving Environment to MMC...
Writing to MMC(1)... done
U-Boot > save

MMC partition switch failed

U-Boot > save
Saving Environment to MMC...
MMC partition switch failed
U-Boot > save
Saving Environment to MMC...
Writing to MMC(1)... done
U-Boot > save
Saving Environment to MMC...
MMC partition switch failed

This issue is caused by the incorrect usage of CONFIG_SYS_MMC_ENV_PART.

CONFIG_SYS_MMC_ENV_PART should be used to specify the mmc partition that stores
the environment variables.

On some imx boards it is been incorrectly used to pass the partition of kernel
and dtb files for the 'mmcpart' script variable.

Remove the CONFIG_SYS_MMC_ENV_PART usage and configure the 'mmcpart' variable
directly.

de7d02aeba mx6qsabresd: add usdhc2 and usdhc4 support
The on-board number of available usdhc devices is something board
specific.  The patch moves CONFIG_SYS_FSL_USDHC_NUM out of
mx6qsabre_common.h and adds usdhc2 and usdhc4 support for mx6qsabresd
board.

To keep the default mmc device for environment same as before (usdhc3),
it moves CONFIG_SYS_MMC_ENV_DEV out of mx6qsabre_common.h and changes
it to 1 for mx6qsabresd.
