* Move lib_$ARCH directories to arch/$ARCH/libPeter Tyser2010-04-13-3607/+0
| | | | | | | | | Also move lib_$ARCH/config.mk to arch/$ARCH/config.mk This change is intended to clean up the top-level directory structure and more closely mimic Linux's directory organization. Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* Generic udelay() with watchdog supportIngo van Lil2009-12-05-1/+1
| | | | | | | | | | | | | 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>

* push LOAD_ADDR out to arch mk filesMike Frysinger2009-09-04-0/+2
| | | | | | | | | | Rather than maintain/extend the current ifeq($(ARCH)) mess that exists in the standalone Makefile, push the setting up of LOAD_ADDR out to the arch config.mk (and rename to STANDALONE_LOAD_ADDR in the process). This keeps the common code clean and lets the arch do whatever crazy crap it wants in its own area. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

* i386: Misc PCI fixupsGraeme Russ2009-09-04-10/+10
| | | | | | | | | | | | | | | | | | | | Change PCI_REGION_MEMORY to PCI_REGION_SYS_MEMORY (Originally done in commit ff4e66e93c1a, regressed by commit 6d7f610b09f8) Cast PCI_ROM_ADDRESS_MASK to u32 Wrap probe_pci_video() call inside #ifdef CONFIG_VIDEO Change call to pci_find_class() to pci_find_devices(). This is based on a patch submitted on 1st March 2007 (Patch that fixes the compilation errors for sc520_cdp board) by mushtaq_k This patch requires that PCI_VIDEO_VENDOR_ID and PCI_VIDEO_DEVICE_ID be specified in the board config file. Dummy values have been added for the SC520 CDP board to enable compilation, but since I do not have one of these, I do know what the values should be Signed-off-by: Graeme Russ <graeme.russ@gmail.com>

* Move architecture specific config.mk files into subdirsPeter Tyser2009-07-21-0/+26
| | | | | | | | This cleans up U-Boot's toplevel directory a bit and makes the architecture 'config.mk' file naming and location similar to board and cpu 'config.mk' files Signed-off-by: Peter Tyser <ptyser@xes-inc.com>
* stdio/device: rework function naming conventionJean-Christophe PLAGNIOL-VILLARD2009-07-18-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Rewrite i386 interrupt handlingGraeme Russ2009-03-20-0/+326
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rewrite interrupt handling functionality for the i386 port. Separated functionality into separate CPU and Architecture components. It appears as if the i386 interrupt handler functionality was intended to allow multiple handlers to be installed for a given interrupt. Unfortunately, this functionality was not fully implemented and also had the problem that irq_free_handler() does not allow the passing of the handler function pointer and therefore could never be used to free specific handlers that had been installed for a given IRQ. There were also various issues with array bounds not being fully tested. I had two objectives in mind for the new implementation: 1) Keep the implementation as similar as possible to existing implementations. To that end, I have used the leon2/3 implementations as the reference 2) Seperate CPU and Architecture specific elements. All specific i386 interrupt functionality is now in cpu/i386/ with the high level API and architecture specific code in lib_i386. Functionality specific to the PC/AT architecture (i.e. cascaded i8259 PICs) has been further split out into an individual file to allow for the implementation of the PIC architecture of the SC520 CPU (supports more IRQs) Signed-off-by: Graeme Russ <graeme.russ at gmail.com>

* bootm: Add subcommandsKumar Gala2008-10-29-0/+3
| | | | | | | | | | | | | | Add the ability to break the steps of the bootm command into several subcommands: start, loados, ramdisk, fdt, bdt, cmdline, prep, go. This allows us to do things like manipulate device trees before they are passed to a booting kernel or setup memory for a secondary core in multicore situations. Not all OS types support all subcommands (currently only start, loados, ramdisk, fdt, and go are supported). Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* bootm: refactor do_reset and os boot function argsKumar Gala2008-08-26-7/+2
| | | | | | | | | | | | There is no need for each OS specific function to call do_reset() we can just do it once in bootm. This means its feasible on an error for the OS boot function to return. Also, remove passing in cmd_tbl_t as its not needed by the OS boot functions. flag isn't currently used but might be in the future so we left it alone.

* Consolidate strmhz() implementationHaavard Skinnemoen2008-08-21-13/+0
| | | | | | | | | | ARM, i386, m68k and ppc all have identical implementations of strmhz(). Other architectures don't provide this function at all.

* Fix fallout from autostart revertKumar Gala2008-08-12-5/+1

* Big white-space cleanup.Wolfgang Denk2008-05-21-75/+75

* allow ports to override go behaviorMike Frysinger2008-04-18-0/+8
| | | | | | Split the arch-specific logic out of the common go code and into a dedicated weak function called do_go_exec() that lives in cpu directories. This will need review from i386/nios people to make sure I didn't break them.

* [new uImage] Add dual format uImage support frameworkMarian Balakowicz2008-02-25-11/+24
| | | | | | | | | | | | | | This patch adds framework for dual format images. Format detection is added and the bootm controll flow is updated to include cases for new FIT format uImages. When the legacy (image_header based) format is detected appropriate legacy specific handling is invoked. For the new (FIT based) format uImages dual boot framework has a minial support, that will only print out a corresponding debug messages. Implementation of the FIT specific handling will be added in following patches. Signed-off-by: Marian Balakowicz <m8@semihalf.com>

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-01-8/+9
| | | | | | | | | | | | | | | | | | | | | 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.
