ARM: pxa: pxa2xx use PSPR for resume address ...

Both lubbock and mainstone suspend to RAM were broken by the same
typo. The linux kernel saves the resume address to PSPR, ie. the scratch
pad register, while it was PSSR which was checked in barebox.

Fixing this typo was tested on mainstone where resume from S3 works.

The commit ea1fb2f by Eric Nelson
imx6-mmdc: fix automatic power down enable in write level calibration

fixed the incorrect usage of the MAPSR register, but there is one more
place where the MAPSR is misused in the exact same way, so fix that as
well.

ARM: Fix bug in remap_range ...

remap_range takes generic MAP_CACHED/MAP_UNCACHED flags which are then
translated into the corresponding ARM specific bits. We call remap_range
internally from dma_alloc_* aswell, but instead of passing the generic
flags we pass the ARM specific bits.
Fix this by creating an internal __remap_range function which takes the
ARM specific bits and use it where appropriate.

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.

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.
