At present binman sets the python path on startup so that it can access the libraries it needs. If we convert to use absolute imports this is not necessary. Move binman to use absolute imports. This enables removable of the path adjusting in Entry also. Signed-off-by: Simon Glass <sjg@chromium.org>

This is the U-Boot SPL (Secondary Program Loader) binary. This is a small
|
|
binary which loads before U-Boot proper, typically into on-chip SRAM. It is
|
|
responsible for locating, loading and jumping to U-Boot. Note that SPL is
|
|
not relocatable so must be loaded to the correct address in SRAM, or written
|
|
to run from the correct address if direct flash execution is possible (e.g.
|
|
on x86 devices).
|
|
|
|
SPL can access binman symbols at runtime. See:
|
|
|
|
'Access to binman entry offsets at run time (symbols)'
|
|
|
|
in the binman README for more information.
|
|
|
|
The ELF file 'spl/u-boot-spl' must also be available for this to work, since
|
|
binman uses that to look up symbols to write into the SPL binary.
