uimage: fix: add can_lseek_backward and use in uimage_open ...

Since commit ce0cc7fe we support forward seek on tftpfs. This feature
breaks the condition to check rather we open an uimage over tftp. Since
backward seeking is the problem here, we add the function
can_lseek_backward and check for it instead of the simple lseek.

usbgadget: fastboot: Allow to automatically export the bbu handlers ...

We have a list of registered handlers which take a barebox update. Do
the next step and allow to automatically export them via fastboot so
that barebox can be updated via fastboot without manually exporting
the partition. Since this may not be desirable in all cases this
behaviour is configurable.

mmc: allow skipping SD card initialization ...

This patch allows to skip SD card initialization for eMMCs by setting
the "no-sd" property in the host controller device tree node. Avoiding
two SD command timeouts speeds up detection time by well over 200 ms.

|Author: Kevin Cernekee <cernekee@gmail.com>

|
|    of: Add helper function to check MMIO register endianness
|
|    SoC peripherals can come in several different flavors:
|
|     - little-endian: registers always need to be accessed in LE mode (so the
|       kernel should perform a swap if the CPU is running BE)
|
|     - big-endian: registers always need to be accessed in BE mode (so the
|       kernel should perform a swap if the CPU is running LE)
|
|     - native-endian: the bus will automatically swap accesses, so the kernel
|       should never swap
|
|    Introduce a function that checks an OF device node to see whether it
|    contains a "big-endian" or "native-endian" property.  For the former case,
|    always return true.  For the latter case, return true iff the kernel was
|    built for BE (implying that the BE MMIO accessors do not perform a swap).
|    Otherwise return false, assuming LE registers.
|
|    LE registers are assumed by default because most existing drivers (libahci,
|    serial8250, usb) always use readl/writel in the absence of instructions
|    to the contrary, so that will be our fallback.

atmel_lcdfb: define power_control gpio in platform_data ...

Simplify board specific code by specifying the power_control
gpio direct in platform data.
Move registration of the GPIO to the driver so we no longer
need to duplicate this for each board.

As an intended side-effect there is no longer
any references to platform_data outside atmel_lcdc_register()
so remove it from struct atmel_lcdfb_info

The implementation assumes that GPIO=0 is the same as no power control.
This prevents us from using any GPIO=0 for power control,
but this is not considered a problem for current users.
Future DT users will not have this limitation.

This commit include a fix so we will actually power
down if requested. Previously this was hardcoded to ON.

mmc_extcsd command: rework ...

This patch is a rework of the mmc_extcsd command:

- Always print registers. Previously we never printed registers that
  were already present in an older version of the spec
- Put register names, access type and width into an array indexed by the
  register number
- Print multibyte registers only once with the resulting value, and not
  bytewise.

There's still more to cleanup, like for example we want to write
multibyte registers once with the complete value, not bytewise. Anyway,
this is a start.
