[PATCH v5 11/22] {usb,tny}-a926x: move reset vector to board code

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



For all Calao USB boards move reset vector to board code.
Introduce two different lowlevel.c files, one
for each processor.
Include renames to make filenames similar.
