* MX31: Add NAND SPL for i.MX31.Magnus Lilja2009-06-21-2/+7
| | | | | | | | | | | | | | | | | | 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>
* ARM1136: Introduce CONFIG_PRELOADER macro.Magnus Lilja2009-06-21-12/+12
| | | | | | | | | Currently CONFIG_ONENAND_IPL is used in a number of #ifdef's in start.S. In preparation for adding support for NAND SPL the macro CONFIG_PRELOADER is introducted and replaces the CONFIG_ONENAND_IPL in start.S. Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>

* arm: unify linker scriptJean-Christophe PLAGNIOL-VILLARD2009-06-12-0/+64
| | | | | | | | | | | | all arm boards except a few use the same cpu linker script so move it to cpu/$(CPU) that could be overwrite in following order SOC BOARD via the corresponding config.mk Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
* arm: timer and interrupt init reworkJean-Christophe PLAGNIOL-VILLARD2009-06-12-6/+6
| | | | | | | | | | | | | | actually the timer init use the interrupt_init as init callback which make the interrupt and timer implementation difficult to follow so now rename it as int timer_init(void) and use interrupt_init for interrupt btw also remane the corresponding file to the functionnality implemented as ixp arch implement two timer - one based on interrupt - so all the timer related code is moved to timer.c Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>

| | | | | | | | | | Switch to the standard CFG_HZ=1000 value, while at it, minor white-space cleanup, remove CFG_CLKS_IN_HZ from config-headers. Tested on mx31ads, provides 2% or 0.4% precision depending on the CONFIG_MX31_TIMER_HIGH_PRECISION flag. Measured with stop-watch on 100s boot-delay. Signed-off-by: Guennadi Liakhovetski <lg@denx.de>

| | | | | | | | | | Correct the mx31_gpio_mux() function to allow changing all i.MX31 IOMUX contacts instead of only the first 256 ones as is the case prior to this patch. Add missing MUX_* macros and update board files to use the new macros. Signed-off-by: Magnus Lilja <lilja.magnus@gmail.com>
* i.MX31: fixed CTRL-C detectionJuergen Kilb2008-07-01-1/+2
| | | | | | | | | | The Register URXD contains status information in bits [15..8]. With status bit 15 set, CTRL-C was reported as 0x8003 instead of 0x03. Therefore CTRL-C was not detected. To solve this, bits [15..8] were masked out now. Signed-off-by: Juergen Kilb <J.Kilb@gmx.de> Acked-by: Felix Radensky <felix@embedded-sol.com>
* Big white-space cleanup.Wolfgang Denk2008-05-21-36/+36
| | | | | | | | | | | This commit gets rid of a huge amount of silly white-space issues. Especially, all sequences of SPACEs followed by TAB characters get removed (unless they appear in print statements). Also remove all embedded "vim:" and "vi:" statements which hide indentation problems. Signed-off-by: Wolfgang Denk <wd@denx.de>
* mx31ads: fix 32kHz clock handlingGuennadi Liakhovetski2008-05-10-2/+2
| | | | | | | | | According to schematics and to RedBoot sources, the MX31ADS uses a 32768Hz oscillator as a SKIL source. Fix previously wrongly assumed 32000Hz value. Also fix a typo when verifying a jumper configuration. While at it, make two needlessly global functions static. Signed-off-by: Guennadi Liakhovetski <lg@denx.de>

| | | | | | | | | | | | | | | | | | | | | | Reverting became necessary after it turned out that the patches in the u-boot-arm repo were modified, and in some cases corrupted.

* | OneNAND Initial Program Loader (IPL) supportKyungmin Park2008-02-14-0/+42
|/ | | | | | | | | | | | | | | | | | 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>

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-7/+11
| | | | | | | | | | | | | | | | | | | | | 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.
