ARM: imx: fsl_esdhc: fix usage of low 4 bits of sysctl register
The low four bits of the SYSCTL register are reserved on the USDHC
controller on i.MX6 and i.MX7 processors, but are used for clocking
operations on earlier models.
Guard against their usage by hiding the bit mask macros on those
processors.
These bits are used to prevent glitches when changing clocks on
i.MX35 et al. Use the RSTA bit instead for i.MX6 and i.MX7.
>From the i.MX6DQ RM:
To prevent possible glitch on the card clock, clear the
FRC_SDCLK_ON bit when changing clock divisor value(SDCLKFS
or DVS in System Control Register) or setting RSTA bit.

usb: musb: Fix hub port setting for SPLIT transactions
The ifdef'ed Linux kernel code uses the 1 based port number, whereas U-Boot
puts a 0 based port number into the register. The reason the 0 based port
number apparently works can probably be taken from the USB 2.0 spec:
8.4.2.2 Start-Split Transaction Token
... The host must correctly set the port field for single and multiple TT
hub implementations. A single TT hub implementation *may ignore* the port
field.
Actually, as far as I understand, a multi TT hub defaults to single TT
(bAlternateSetting: 0) until switched via SetInterface, so even "port 42"
would work.
The change was verified by hardcoding the port number to a wrong value,
SPLIT transactions kept working (although using a DWC2 instead of MUSB).
Tested hubs are the RPi onboard SMC9514 and an external "05e3:0608
Genesys Logic, Inc. USB-2.0 4-Port HUB". The former is a multi TT hub,
the latter single TT only.

ARM: uniphier: set DTB file name to fdt_file environment
When we want to boot Linux with a DTB file downloaded from a TFTP
server or somewhere, we need to know the file name to be downloaded.
Assume the U-Boot configuration is shared among some similar boards.
If they are similar enough, the difference only appears in device
trees. The build procedure would be like this:
- Board A: make foo_common_defconfig && make DEVICE_TREE=foo_board_a
- Board B: make foo_common_defconfig && make DEVICE_TREE=foo_board_b
- Board C: make foo_common_defconfig && make DEVICE_TREE=foo_board_c
In this case, the U-Boot image contains nothing about the DTB file name
it is running with. (CONFIG_DEFAULT_DEVICE_TREE is not helpful for this
purpose because it is painful to change it from "make menuconfig" for
each board.)
This commit allows to lookup the DTB file name based on the compatible
string and set it to "fdt_file" environment. Then "tftpboot $fdt_file"
will download the file we want.

"ethaddr", "eth1addr", "eth2addr" must exist in order to fix

of "ethernet%d", then get its MAC address from corresponding
