Subject: powerpc: add --bss-plt to LDFLAGS
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=039b77396abb0ed78af34dadbd0786dfaf0e6aa9;p=u-boot.git

powerpc: add --bss-plt to LDFLAGS

With some versions of gcc (that we know of 4.6.3 and 4.8.2 are affected)
it is necessary to specify --bss-plt to get the final blrl in the
_GOT2_TABLE_. Without this the last symbol does not get it's address
relocated.  For the P2041RDB board this ended up being
NetArpWaitTimerStart which caused the ARP packets to timeout
immediately.
