2009-12-05Generic udelay() with watchdog supportIngo van Lil
According to the PPC reference implementation the udelay() function is responsible for resetting the watchdog timer as frequently as needed. Most other architectures do not meet that requirement, so long-running operations might result in a watchdog reset. This patch adds a generic udelay() function which takes care of resetting the watchdog before calling an architecture-specific __udelay(). Signed-off-by: Ingo van Lil <inguin@gmx.de>

2009-08-21ARM: compiler options cleanup - improve tool chain supportWolfgang Denk
For some time there have been repeated reports about build problems with some ARM (cross) tool chains. Especially issues about (in)compatibility with the tool chain provided runtime support library libgcc.a caused to add and support a private implementation of such runtime support code in U-Boot. A closer look at the code indicated that some of these issues are actually home-made. This patch attempts to clean up some of the most obvious problems and make building of U-Boot with different tool chains easier: - Even though all ARM systems basicy used the same compiler options to select a specific ABI from the tool chain, the code for this was distributed over all cpu/*/config.mk files. We move this one level up into lib_arm/config.mk instead. - So far, we only checked if "-mapcs-32" was supported by the tool chain; if yes, this was used, if not, "-mabi=apcs-gnu" was selected, no matter if the tool chain actually understood this option. There was no support for EABI conformant tool chains. This patch implements the following logic: 1) If the tool chain supports "-mabi=aapcs-linux -mno-thumb-interwork" we use these options (EABI conformant tool chain). 2) Otherwise, we check first if "-mapcs-32" is supported, and then check for "-mabi=apcs-gnu" If one test succeeds, we use the first found option. 3) In case 2), we also test if "-mno-thumb-interwork", and use this if the test succeeds. [For "-mabi=aapcs-linux" we set "-mno-thumb-interwork" mandatorily.] This way we use a similar logic for the compile options as the Linux kernel does. - Some EABI conformant tool chains cause external references to utility functions like raise(); such functions are provided in the new file lib_arm/eabi_compat.c Note that lib_arm/config.mk gets parsed several times, so we must make sure to add eabi_compat.o only once to the linker list.

2009-06-21MX31: Add NAND SPL for i.MX31.Magnus Lilja
This patch adds the NAND SPL framework needed to boot i.MX31 boards from NAND. It has been tested on a i.MX31 PDK board with large page NAND. Small page NANDs should work as well, but this has not been tested. Note: The i.MX31 NFC uses a non-standard layout for large page NANDs, whether this is compatible with a particular setup depends on how the NAND device is programmed by the flash programmer (e.g. JTAG debugger). The patch is based on the work by Maxim Artamonov. Signed-off-by: Maxim Artamonov <scn1874@yandex.ru> Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>

2008-02-14OneNAND Initial Program Loader (IPL) supportKyungmin Park
This patch enables the OneNAND boot within U-Boot. Before this work, we used another OneNAND IPL called X-Loader based on open source. With this work, we can build the oneboot.bin image without other program. The build sequence is simple. First, it compiles the u-boot.bin Second, it compiles OneNAND IPL Finally, it becomes the oneboot.bin from OneNAND IPL and u-boot.bin The mechanism is similar with NAND boot except it boots from itself. Another thing is that you can only use the OneNAND IPL only to work other bootloader such as RedBoot and so on. Signed-off-by: Kyungmin Park <kyungmin.park@samsung.com>

2006-09-01Add support for a saving build objects in a separate directory.Marian Balakowicz
Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
