u-boot.git/drivers/bios_emulator, branch v2011.09 Unnamed repository; edit this file 'description' to name the repository. Switch from archive libraries to partial linking 2010-11-17T20:02:18+00:00 Sebastien Carlier sebastien.carlier@gmail.com 2010-11-05T14:48:07+00:00 6d8962e814c15807dd6ac5757904be2a02d187b8 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 <sebastien.carlier@gmail.com> 
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.

ati_radeon: Support PCI virtual not eq bus mapping. 2010-04-08T13:30:47+00:00 Ed Swarthout Ed.Swarthout@freescale.com 2010-03-31T20:52:40+00:00 f6a7a2e88854666e6a9ede50891fe415e803ace2 Use pci_bus_to_virt() to convert the bus address from the BARs to virtual address' to eliminate the direct mapping requirement. Rename variables to better match usage (_phys -> _bus or no-suffix) This fixes the mpc8572ds CONFIG_PHYS_64BIT mode failure: "videoboot: Video ROM failed to map!"
