omap socfpga: Switch in flash env loading to use different config ...

On these systems, the base arch has code to load the in flash
environment from a file located in a FAT filesystem.  This was
controlled by the config option DEFAULT_ENVIRONMENT.  However, that
option turns on compiling the env into the barebox binary itself, as a
backup if the in flash env can't be loaded.

Most other boards have in flash env support unconditionally.  But omap
and socfpga also have xloader configurations, which aren't supposed to
have environment support, either in flash or compiled in.  If the in
flash env code were unconditional, then the xloaders would gain it.

So the code depends on ENV_HANDLING, which is only set on those boards
that are supposed to have an in flash env and not set on all the
boards that aren't supposed to have it.

If someone wanted to create a board that did have a saved env, but
used an alternate to this generic omap/socfpga file in FAT method,
then they'd probably want to create a new config option to control
this code and have it not be enabled for their board.

hush: Add missing initialize_context() in some places ...

Before a context can be used it must be initialized. This was forgotten
in several places. Add the missing calls to initialize_context().

fcntl: Fix O_CREAT clashing with O_RWSIZE_8 ...

O_CREAT and O_RWSIZE_8 are both defined as 0100. Fix this by moving the
O_RWSIZE_* flags to unused bits.

This bug leads to incomplete writes when the destination file is created
and mem_write is involved, for example with the memcpy command:

memcpy -s /some/file -d /dev/ram0 0 0 10

In this case only 8 bytes will be copied and it will be done using 8
byte accesses which may not work properly if the destination is not
sufficiently aligned, i.e.:

memcpy -s /some/file -d /dev/ram0 0 1 8

arm/cpu: Avoid multiple definitions of barebox_arm_entry ...

All versions of barebox_arm_entry (in uncompress.c, start.c and
start-pbl.c) appear to be doing exacty the same thing. So move the
definition into a separate file and use IS_ENABLED macro to avoid
re-definition.

arm/cpu/start.c: Distil some common code in __start(). ...

Both barebox_boarddata and barebox_boot_dtb perform essentially the
same function -- hold a pointer to a chunk of private data. Since only
one variable is ever used at any given time we may as well merge those
two variable into one. This also allows us to share more code between
two boot paths (board data vs. device tree)

ARM: imx: clocksource: add new DT compatible ...

The i.MX6 DL/S DT has been changed to use more specific compatibles as
GPTv2 has a different programming model for modes used in Linux. This
difference doesn't matter for Barebox, but the old mx31 compatible has
been dropped from the DT, so we need to match on the one still present.

In order to make the system compliant to the ARMv7 ARM RevC clarifications
regarding conflicting memory aliases the shared override bit needs to be
set. This needs to be done in the bootloader, as the kernel will not apply
any modifications to the AUX_CTRL register by default, as it is a secure only

ARM: l2x0: move outer cache flush on disable to user ...

There are systems like the Calxeda Highbank, which need to do SMC

want to replace the outer cache disable function with their own.

As the cache flush before entering the boot target is still needed
and to avoid exposing L2C internals to the architectures move the
flush before disable into the only current user.
