Anton sent a similar patch to Linus, here is his comment:
<<
Recent toolchains force the TOC to be 256 byte aligned. We need
to enforce this alignment in our linker script, otherwise pointers
to our TOC variables (...) could be incorrect.

As part of setting up GCOV data structures correctly, GCC/GCOV generates
a bunch of constructor routines that the C runtime is expected to run
really early on.
skiboot was not running GCC generated constructors. Luckily, it's really
easy to do so.
This patch will run GCC constructors very early on during boot (if there
are any)

When built with gcov, skiboot is >1MB (closer to 1.5MB) and there
were a few assumptions about skiboot being <1MB.
The biggest one was that when code got larger, we'd have the sbss section
start in the middle of code, so that when we were going to relocate ourselves,
we'd only get the first 1MB of skiboot relocated, which excluded the
_DYNAMIC section, meaning that relocate() would not find the right
sections.
We also needed to not start writing over random parts of skiboot.

We use a double link technique, doing a first pass with a .o containing
a dummy symbol map, then re-linking with a new .o

At present CPU control area ntuple in SPIRA structure is NULL.
ATTN component in Service Processor side checks for this field and if its empty,
it logs hardcoded SRC (0xBB821410) and generates SYSDUMP. So we have 1 SRC for
all failure (assert call) from OPAL side. This makes difficult to debug the issue.
Service processor provides attention area interface (FIPS PHyp Attentions spec),
so that we can pass SRC and user data (error message) to service processor.
This will helps us identify different failures in OPAL.
This patch enables attention area and provides interface (update_sp_attn_area())
to add src and user data (error message) through assert macro.
Attention SRC format:
1st byte - Opal src type
2-4 bytes - Holds the address of the assert function call
