Blackfin: use common LDSCRIPT logic

2011-06-03T17:26:45Z

Now that common code is a bit smarter when it comes to default LDSCRIPT values, rename the default Blackfin file and drop the Blackfin-specific config.mk logic. Signed-off-by: Mike Frysinger

Blackfin: default to L1 bank A when L1 bank B does not exist

2011-04-08T04:44:26Z

Some parts lack Bank B in L1 data, so have the linker script fall back to Bank A when that happens. This way we can still leverage L1 data. Signed-off-by: Mike Frysinger

Blackfin: only check for os log when we have external memory

2011-04-08T04:44:26Z

If the part has no external memory configured, then there will be no os log for us to check, and any attempt to access that memory will trigger hardware errors. Signed-off-by: Mike Frysinger

Blackfin: fix bd_t handling

2011-04-08T04:44:26Z

The recent global data changes (making the size autogenerated) broke the board info handling on Blackfin ports as we were lying and lumping the bd_t size in with the gd_t size. So use the new dedicated bd_t size to setup its own address in memory. Signed-off-by: Mike Frysinger

Blackfin: move CONFIG_BFIN_CPU back to board config.h

2011-04-08T04:44:26Z

This is a revert of 821ad16fa9900c as Wolfgang doesn't like the new code. Signed-off-by: Mike Frysinger

Blackfin: make sure bss len is multiple of 4 bytes

2010-11-18T09:38:19Z

The Blackfin on-chip BootROM requires that fill operations (which is used for the bss) be aligned to 4 bytes (base addr and total len). Plus, the Blackfin early init asm code assumes the same thing. So rather than making things work for no real gain, make sure the bss len is padded to 4 bytes in the linker script. Signed-off-by: Mike Frysinger

Blackfin: stick ins/outs funcs into their own .text section

2010-11-18T09:38:19Z

This lets the linker garbage collect these functions when they aren't actually used by placing them into the standard .text. section. Signed-off-by: Mike Frysinger

Switch from archive libraries to partial linking

2010-11-17T20:02:18Z

Before this commit, weak symbols were not overridden by non-weak symbols found in archive libraries when linking with recent versions of binutils. As stated in the System V ABI, "the link editor does not extract archive members to resolve undefined weak symbols". This commit changes all Makefiles to use partial linking (ld -r) instead of creating library archives, which forces all symbols to participate in linking, allowing non-weak symbols to override weak symbols as intended. This approach is also used by Linux, from which the gmake function cmd_link_o_target (defined in config.mk and used in all Makefiles) is inspired. The name of each former library archive is preserved except for extensions which change from ".a" to ".o". This commit updates references accordingly where needed, in particular in some linker scripts. This commit reveals board configurations that exclude some features but include source files that depend these disabled features in the build, resulting in undefined symbols. Known such cases include: - disabling CMD_NET but not CMD_NFS; - enabling CONFIG_OF_LIBFDT but not CONFIG_QE. Signed-off-by: Sebastien Carlier

Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value

2010-10-26T19:05:30Z

CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not being able to use "sizeof(struct global_data)" in assembler files. Recent experience has shown that manual synchronization is not reliable enough. This patch renames CONFIG_SYS_GBL_DATA_SIZE into GENERATED_GBL_DATA_SIZE which gets automatically generated by the asm-offsets tool. In the result, all definitions of this value can be deleted from the board config files. We have to make sure that all files that reference such data include the new file. No other changes have been done yet, but it is obvious that similar changes / simplifications can be done for other, related macro definitions as well.
