* | Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* post/drivers/i2c.c: fix compile errorWolfgang Denk2010-10-27-1/+1
| | | | | | | | | | | | | | | | | Commit 7e263ce "post/i2c: Clean up detection logic" added a "const" qualifier to the declaration of i2c_addr_list[], missing the fact that the list gets modified later in the code, which results in build errors like these: i2c.c: In function 'i2c_post_test': i2c.c:88: error: assignment of read-only location Remove the incorrect "const".

* post/i2c: Add ability to ignore I2C devicesPeter Tyser2010-10-22-2/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the ability to not report an I2C POST error for a set of given I2C addresses on bootup. This is useful for cases when a device may or may not be present, and neither case is considered an error. For example: - Some form factors such as XMC and Compact PCI Express have an I2C EEPROM whose address changes based on geographical address. Eg installed in one slot its EEPROM address is, 0x50, in another its 0x51, etc. This allows multiple devices to have their EEPROMs present on the same I2C bus. Thus the I2C devices present for an XMC or CPCIe card depend on if and where other cards are installed in the same system. - Some cards have optional I2C devices. Eg one hardware build configuration has different I2C devices than another and software can't determine if the optional device should be present or not. - Some cards have optional daughtercards with I2C devices on them. - I2C EEPROMs address range depends on their size. Its possible to support differently size EEPROMs by only probing the EEPROM's base address and ignoring the other addresses that are impacted by its size. A new CONFIG_SYS_POST_I2C_IGNORES define has been added which specifies a list of I2C addresses for the I2C POST to ignore.

* post/i2c: Don't probe address 0Peter Tyser2010-10-22-2/+4
| | | | | | | | | | | | | | | | | According to the I2C specification device address 0 is the "general call address", ie a broadcast address. The I2C specification states that the format of a general call uses at least 2 bytes, which U-Boot's probing routine does not adhere to. Not probing device address 0 will prevent possible issues with devices that accept general calls. Additionally, this change shouldn't reduce POST coverage since each I2C device should still be accessed via its own, unique address.

* Expand POST memory test to support arch-depended implementation.York Sun2010-10-19-16/+52
| | | | | | | | | | | | | Add weak functions to enable architecture depended preparation, address advancing, cleaning up and error handling. These weak functions provides the framwork to implemente arch/platform dependent code for initializing/maintenance/restore the start address, size, physical address as well as memory mapping before/between/after memory test. arch_memory_failure_handle can also be implemented in case more care is needed for arch/platform.

Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>

| * POST: move CONFIG_POST to MakefilesYuri Tikhonov2008-04-22-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | Introduce the new logical option CONFIG_HAS_POST which is set when the platform has CONFIG_POST set. Use CONFIG_HAS_POST in the post/ Makefiles to determine should the POST libs be compiled for the selected target platform, or not. To avoid breaking u-boot linking process, the empty post/libpost.a file is created for platforms which do not have POSTs.

* | LWMON5: POST RTC fixYuri Tikhonov2008-03-20-0/+15
|/ | | | | | | | | | | | | | | | | Modify the RTC API to provide one a status for the time reported by the rtc_get() function: 0 - a reliable time is guaranteed, < 0 - a reliable time isn't guaranteed (power fault, clock issues, and so on). The RTC chip drivers are responsible for providing this info if the corresponding chip supports such functionality. If not - always report that the time is reliable. The POST RTC test was modified to detect the RTC faults utilizing this new rtc_get() feature. Signed-off-by: Yuri Tikhonov <yur@emcraft.com>
