Subject: [PATCH 1/3] romfile: implement a generic loader
|
|
|
|
romfile_loadfile_g:
|
|
Based on romfile_loadfile but more flexible. User has to supply pointer
|
|
to a malloc function and the number of trailing padding bytes. Thus, any
|
|
memory region may be used.
|
|
|
|
romfile_loadfile:
|
|
It is now a wrapper around romfile_loadfile_g. Functionality is the same.
