2009-01-07Blackfin arch: fix bugs in linker script when using upstream binutilsBernd Schmidt
Fix a few problems I discovered when building a kernel with upstream CVS binutils. We have to add the NOTES macro to our linker script, since a kernel built with --build-id is otherwise unable to boot. Last time NOTES was added, it broke things, but the definition of the macro has changed not to rely on parts of the linker script that aren't present on Blackfin. I also noticed that _l2_lma_start does not point into the kernel image, but rather somewhere in L1/L2 space, which seems unintended. Also, when the L2 section was added to the linker script, the part following it which computes then length of the init section was not updated.
