[ Upstream commit187bea4726
] When CONFIG_FORTIFY_SOURCE is set, memcpy() checks the potential buffer overflow and panics. The code in sofcpga bootstrapping contains the memcpy() calls are mistakenly translated as the shorter size, hence it triggers a panic as if it were overflowing. This patch changes the secondary_trampoline and *_end definitions to arrays for avoiding the false-positive crash above. Fixes:9c4566a117
