/*
* This linker script is used to link rmodules (relocatable modules). It
* links at zero so that relocation fixups are easy when placing the binaries
* anywhere in the address space.
*
* NOTE: The program's loadable sections (text, module_params, and data) are
* packed into the flat blob. The rmodule loader assumes the entire program
* resides in one contiguous address space. Therefore, alignment for a given
* section (if required) needs to be done at the end of the preceeding section.
* e.g. if the data section should be aligned to an 8 byte address the text
* section should have ALIGN(8) at the end of its section. Otherwise there
* won't be a consistent mapping between the flat blob and the loaded program.
