images: Embedsky E9: use image name like the rest of boards ...

Use name similar to other boards thus remove freescale from image
name since this is not a Freescale board, move SoC type after
company name.

So image name changed from barebox-freescale-imx6q-embedsky-e9.img to
barebox-embedsky-imx6q-e9.img

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.

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

Often enough the biggest free region spans most free RAM, so
it doesn't add much value to test the remaining free regions. This
patch changes the default behaviour to only test the biggest free

rework remap_range ...

remap_range is for remapping regions with different cache attributes.
It is implemented for ARM and PowerPC only, the other architectures only
provide stubs.
Currently the new cache attributes are passed in an architecture specific
way and the attributes have to be retrieved by calls to
mmu_get_pte_cached_flags() and mmu_get_pte_uncached_flags().
Make this simpler by providing architecture independent flags which can
be directly passed to remap_range()
Also provide a MAP_ARCH_DEFAULT flag and a arch_can_remap() function.
The MAP_ARCH_DEFAULT defaults to whatever caching type the architecture
has as default. the arch_can_remap() function returns true if the
architecture can change the cache attributes, false otherwise. This
allows the memtest code to better find out what it has to do.

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)

Make sure that the DT passed to Linux reflects the actual number of CPU

but the DTs have the maximum number of cores specified, this just deletes
any nonexistent CPU core nodes.

ARM: Allow compressed dtb binaries ...

In the current multi image build process the DTBs end up uncompressed
in the PBL. This can be annoying because the PBL is often very size
constrained.
This patch allows to put the DTBs in as lzo compressed binary into
the PBL. Since lzo offers quite good compression ratios for DTBs no
other compression algorithm has been implemented for now.
Boards which want to use the compressed DTBs only have to change
the __dtb_ prefix in the DTB name to __dtb_z_. Also they should select
ARM_USE_COMPRESSED_DTB to make sure barebox supports uncompressing
the DTB.
