* | Switch from archive libraries to partial linkingSebastien Carlier2010-11-17-22/+20
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* Replace CONFIG_RELOC_FIXUP_WORKS by CONFIG_NEEDS_MANUAL_RELOCWolfgang Denk2010-10-29-1/+1
| | | | | | | | | | | By now, the majority of architectures have working relocation support, so the few remaining architectures have become exceptions. To make this more obvious, we make working relocation now the default case, and flag the remaining cases with CONFIG_NEEDS_MANUAL_RELOC.

* 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.

* ppc4xx: Use common ns16550 functions in 4xx UART POST driverStefan Roese2010-10-04-280/+22
| | | | | | | | | | | | | | | | | This patch changes the PPC4xx POST UART driver to use the common NS16550 functions for receiving and sending. Additionally the local function for SoC divisor setup are removed. Instead the functions from arch/powerpc/cpu/ppc4xx/4xx_uart.c are used. This removes code duplication. Also the common CONFIG_SYS_NS16550_COMx defines are now used to describe the POST UART's. And a compile breakage is fixed, introduced by a git merge of the ppc4xx/next branch into master. Now "ppc4xx.h" is moved to "asm/ppc4xx.h". Fixed as well with this patch. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch fixes a problem in the PPC4xx POST UART driver. This driver incorrectly used the in/out8() io-accessor functions. This could lead to problems since these functions don't guarantee execution ordering. This patch now replaces these functions with the correct ones.

* Rename getenv_r() into getenv_f()Wolfgang Denk2010-08-04-1/+1
| | | | | | | | | | | | | | | | | | | While running from flash, i. e. before relocation, we have only a limited C runtime environment without writable data segment. In this phase, some configurations (for example with environment in EEPROM) must not use the normal getenv(), but a special function. This function had been called getenv_r(), with the idea that the "_r" suffix would mean the same as in the _r_eentrant versions of some of the C library functions (for example getdate vs. getdate_r, getgrent vs. getgrent_r, etc.). Unfortunately this was a misleading name, as in U-Boot the "_r" generally means "running from RAM", i. e. _after_ relocation. To avoid confusion, rename into getenv_f() [as "running from flash"] Signed-off-by: Wolfgang Denk <wd@denx.de> Acked-by: Detlev Zundel <dzu@denx.de>

* POST: Remove duplicated post_hotkey_pressed() functionsStefan Roese2009-12-07-0/+16
| | | | | | | | | | | | | This patch introduces a weak default function for post_hotkey_pressed(), returning 0, for boards without hotkey support. The long-running tests won't be started on those boards. This default function was implemented in many board directories. By implementing this weak default we can remove all those duplicate versions. Boards with hotkey support, can override this weak default function by defining one in their board specific code. Signed-off-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | So far the console API uses the following naming convention: ======Extract====== typedef struct device_t; int device_register (device_t * dev); int devices_init (void); int device_deregister(char *devname); struct list_head* device_get_list(void); device_t* device_get_by_name(char* name); device_t* device_clone(device_t *dev); ======= which is too generic and confusing. Instead of using device_XX and device_t we change this into stdio_XX and stdio_dev This will also allow to add later a generic device mechanism in order to have support for multiple devices and driver instances.

* FPU POST: fix warnings when building with 2.18 binutilsYuri Tikhonov2009-01-24-0/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When compile u-boot with the 2.18 binutils the following warning messages for each object file in post/lib_ppc/fpu/ is produced at the linking stage: post/libpost.a(acc1.o) uses hard float, u-boot uses soft-float ... This is because of the fact that, in general, the soft-float and hard-float ABIs are incompatible; the 2.18 binutils do checking of the Tag_GNU_Power_ABI_FP attribute of the files to be linked, and produce the worning like above if these are not compatible. The incompatibility of ABIs is concerned only the float values: e.g. the soft-float ABI assumes the float argument passing in the pair of rX registers, and the hard-float ABI assumes passing of the float argument in the fX register. When we don't pass the float arguments between the functions compiled with different floatness, then such an application will work correctly. This is the case for the FPU POST: u-boot (compiled with soft-float) doesn't pass to (and doesn't get from) the FPU POST functions any floats; there are no functions exported from the post/lib_ppc/fpu/ objects which would work with float parameters/returns too. So, we can reassure the linker not to worry about the difference in ABI attributes of linking files just by setting the 'soft-float' attribute for the objects in post/lib_ppc/fpu. And this patch does this. Also, to avoid passing both soft- and hard-float options in CFLAGS when compiling the files from post/lib_ppc/fpu (which is OK, but looks rather dirty) this patch removes the soft-float string from CFLAGS in post/lib_ppc/fpu/Makefile.
