fs: Fix can_lseek_backward() ...

To quote corresponding man page:

"... Upon successful completion, lseek() returns the resulting offset
location as measured in bytes from the beginning of the file."

Which for lseek(fd, 0, SEEK_SET) would be 0, so returning 'ret' as
final step of the function would mean it'd never return anything but 0
as well. Change the code to explicitly return '1' to fix the problem.

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.

This patch adds an API to automatically enable either hardware components

ARM: boards: phytec-som-am335x: Add unified MLO ...

PCM-060 modules only have one-bank RAMs populated, which allows us to
find out the populated RAM size at run-time.

Therefore, a new entry point was create 'PHYTEC_ENTRY_UNIFIED_MLO'. This
creates a MLO for all modules of one family and all existing PCM-060
MLOs were replaced with this new entry point. To provide backward
compatibility for older modules, these were not affected.

In the first step generic RAM timings for the module family get loaded,
because RAM accesses are only possible with an initialized controller.
After that, the RAM size will be calculated and the RAM controller gets
reinitialized with the correct RAM timings.

commands: nv: assure error code will be returned when an error occurred ...

Due to iteration over possibly multiple variables, the return value of
an individual call to nvvar_remove() / nvvar_add() gets lost.

This will result in do_nv() returning success (0) if any variable
processing failed as long as processing of the last variable succeeded.

Processing will not be aborted on individual errors, such as the 'cp'
handles it for invalid files.
