The patman directory has a number of modules which are used by other tools in U-Boot. This makes it hard to package the tools using pypi since the common files must be copied along with the tool that uses them. To address this, move these files into a new u_boot_pylib library. This can be packaged separately and listed as a dependency of each tool. Signed-off-by: Simon Glass <sjg@chromium.org>

"""Support for ARM's Firmware Image Package (FIP) format
|
|
|
|
FIP is a format similar to FMAP[1] but with fewer features and an obscure UUID
|
|
instead of the region name.
|
|
|
|
It consists of a header and a table of entries, each pointing to a place in the
|
|
firmware image where something can be found.

If ATF updates, run this program to update the FIT_TYPE_LIST.
