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>

x86 CPUs start up in 16-bit mode, even if they are 32-bit CPUs. This code
|
|
must be placed in the top 64KB of the ROM. The reset code jumps to it. This
|
|
entry holds that code. It is typically placed at offset
|
|
CONFIG_SYS_X86_START16. The code is responsible for changing to 32-bit mode
|
|
and jumping to U-Boot's entry point, which requires 32-bit mode (for 32-bit
|
|
U-Boot).
|
|
|
|
For 32-bit U-Boot, the 'x86-start16' entry type is used instead.
