It can be optimised out by the compiler otherwise resulting in obscure errors like a board not booting. This has been documented in README since 2006 when these were first fixed up for GCC 4.x.

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>
Overo expansion boards contain an i2c eeprom to identify themselves. This patch adds code to read and parse the eeprom contents. It prints the expansion board name and revision and modifies environment variables as appropriate. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
The change is currently needed to be able to remove the board configuration scripting from the top level Makefile and replace it by a simple, table driven script. Moving this configuration setting into the "CONFIG_*" name space is also desirable because it is needed if we ever should move forward to a Kconfig driven configuration system.

An upcoming version of Overo uses a Wifi/BT module with 1.8V signaling, eliminating the need for an external transceiver to handle the level shifting. This patch detects whether an external transceiver is present and adjusts the pinmux settings as appropriate.

Confiures GPMC timings for both chips and also configures pinmux for GPIO_65, which is used as the interrupt signal for the second chip Signed-off-by: Scott Ellis <scott@jumpnowtek.com> Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
The latest Overo COM modules encode their revision number on GPIOs 115, 113, and 112. All boards to date have no pullups on these pins and hence appear as revision 0. This patch reads and prints the revision information. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
This patch modifies the pinmux setup for MMC1_CLK and MMC3_CLK to enable the input driver. MMC2_CLK was already properly configured. Signed-off-by: Steve Sakoman <steve@sakoman.com> Signed-off-by: Sandeep Paulraj <s-paulraj@ti.com>
