For the bringup of the RK3368, we need to support TPL and SPL running from different addresses... which requires both stages to use a distinct TEXT_BASE.
This commit adds support for having a separate LDSCRIPT for TPL (which is expected to make use of the TPL_MAX_SIZE define) and for having a the option of defining TPL_TEXT_BASE and having the TPL stage linked against this address.
Note that the handling of the TEXT_BASE is designed to not interfere with the previous assumption that SPL_TEXT_BASE should be used for TPL as well, unless TPL_TEXT_BASE is defined. For this reason, the test in Makefile.spl uses the following (seemingly redundant checks):
- looks for $(SPL_TPL_)TEXT_BASE
- looks for SPL_TEXT_BASE (even when building in TPL)
