As meta-arm has this version in master, but not in dunfell, temporarily overlay corresponding patches locally - could be removed for the next release. Need to alter FILESEXTRAPATHS for bbappend to locate local patches. Since meta-arm/dunfell has 3.8-specific patches in SRC_URI, let's redefine it completely to match 3.11-specific patch list in meta-arm/master. Last, but not least, guard all upstream recipe varibales with "ti-soc" override to only affect platforms in meta-ti, but not any other BSPs.

Subject: [PATCH 1/3] libutils: provide empty __getauxval() implementation
|
|
|
|
Never version of libgcc are built with LSE implementation in mind. To
|
|
determine if LSE is available on platform it calls __getauxval(), so in
|
|
some cases we can get undefined reference to __getauxval() error.
|
|
|
|
Prominent case is libgcc_eh.a library, which is used by C++ TAs. Exception
|
|
handler depends on atomic operations, so it tries to call
|
|
init_have_lse_atomics() first. This function in turn calls __getauxval(),
|
|
which causes linking error.
|
|
|
|
In the future we can make __getauxval() to return actual platform
|
|
capabilities.
