* Added arch_lmb_reserve to allow arch specific memory regions protectionKumar Gala2008-10-18-22/+28
| | | | | | | | | Each architecture has different ways of determine what regions of memory might not be valid to get overwritten when we boot. This provides a hook to allow them to reserve any regions they care about. Currently only ppc, m68k and sparc need/use this. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

* fdt: Overwrite /chosen node in bootm if it already exists in the dtbStefan Roese2008-10-01-1/+1
| | | | | | | | Set force parameter in fdt_chosen() call in do_bootm_linux() call. Without this, the chosen node is not overwritten if it already exists. Signed-off-by: Stefan Roese <sr@denx.de>
* powerpc: Fix bootm to boot up again with a RamdiskHeiko Schocher2008-09-13-2/+3
| | | | | | | | | | | | | | | Commit 2a1a2cb6 didnt remove the dummy mem reservation in fdt_chosen, and this stopped Linux from booting with a Ramdisk. This patch fixes this, by deleting the useless dummy mem reservation. When booting with a Ramdisk, a fix offset FDT_RAMDISK_OVERHEAD is now added to of_size, so we dont need anymore a dummy mem reservation. I measured the value of FDT_RAMDISK_OVERHEAD on a MPC8270 based system (=0x44 bytes) and rounded it up to 0x80).

* bootm: refactor do_reset and os boot function argsKumar Gala2008-08-26-7/+4
| | | | | | | | | | | | 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.

* fdt: refactor initrd related codeKumar Gala2008-08-26-26/+2
| | | | | | | | | Created a new fdt_initrd() to deal with setting the initrd properties in the device tree and fixing up the mem reserve. We can use this both in the choosen node handling and lets us remove some duplicated code when we fixup the initrd info in bootm on PPC. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* fdt: refactor fdt resize codeKumar Gala2008-08-26-28/+4
| | | | | | | Move the fdt resizing code out of ppc specific boot code and into common fdt support code. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: move lmb into the bootm_headers_t structureKumar Gala2008-08-26-1/+1
| | | | | | | | To allow for persistent state between future bootm subcommands we need the lmb to exist in a global state. Moving it into the bootm_headers_t allows us to do that. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor fdt locating and relocation codeKumar Gala2008-08-26-484/+8
| | | | | | | Move the code that handles finding a device tree blob and relocating it (if needed) into common code so all arch's have access to it. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor ramdisk locating codeKumar Gala2008-08-26-11/+5
| | | | | | | | Move determing if we have a ramdisk and where its located into the common code. Keep track of the ramdisk start and end in the bootm_headers_t image struct. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* bootm: refactor entry point codeKumar Gala2008-08-26-19/+3

* Update linux bootm to support ePAPR client interfaceKumar Gala2008-08-19-10/+23
| | | | | | | | The ePAPR spec has some subtle differences from the current device tree based boot interface to the powerpc linux kernel. The powerpc linux kernel currently ignores the differences that ePAPR specifies. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Fix fallout from autostart revertKumar Gala2008-08-12-4/+1
| | | | | | | | The autostart revert caused a bit of duplicated code as well as code that was using images->autostart that needs to get removed so we can build again. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* Fix LMB type issuesAndy Fleming2008-07-10-1/+2
| | | | | | | The LMB code now uses phys_addr_t and phys_size_t. Also, there were a couple of casting problems in the bootm code that called the LMB functions. Signed-off-by: Andy Fleming <afleming@freescale.com>
* Fix compiler warningsKumar Gala2008-07-10-2/+2

* Fix printf errors.Andrew Klossner2008-07-09-4/+4
| | | | | | | | | | | | The compiler will help find mismatches between printf formats and arguments if you let it. This patch adds the necessary attributes to declarations in include/common.h, then begins to correct the resulting compiler warnings. Some of these were bugs, e.g., "$d" instead of "%d" and incorrect arguments. Others were just annoying, like int-long mismatches on a system where both are 32 bits. It's worth fixing the annoying errors to catch the real ones. Signed-off-by: Andrew Klossner <andrew@cesa.opbu.xerox.com>

* Resize device tree to allow space for board changes and the chosen nodeAndy Fleming2008-06-28-8/+58
| | | | | | | | | | | | | Current code requires that a compiled device tree have space added to the end to leave room for extra nodes added by board code (and the chosen node). This requires that device tree creators anticipate how much space U-Boot will add to the tree, which is absurd. Ideally, the code would resize and/or relocate the tree when it needed more space, but this would require a systemic change to the fdt code, which is non-trivial. Instead, we resize the tree inside boot_relocate_fdt, reserving either the remainder of the bootmap (in the case where the fdt is inside the bootmap), or adding CFG_FDT_PAD bytes to the size. Signed-off-by: Andy Fleming <afleming@freescale.com>
* Change lmb to use phys_size_t/phys_addr_tBecky Bruce2008-06-12-7/+9
| | | | | | | | | | | This updates the lmb code to use phys_size_t and phys_addr_t instead of unsigned long. Other code which interacts with this code, like getenv_bootm_size() is also updated. Booted on MPC8641HPCN, build-tested ppc, arm, mips. Signed-off-by: Becky Bruce <becky.bruce@freescale.com>

* Support legacy multi-type images without FDT section.Nick Spence2008-05-10-3/+2
| | | | | | | | | | | | This patch enables legacy multi-type images containing only a Linux kernel and root file system to be loaded, maintaining compatibility with previous versions of u-boot. This is required when using old image files such as a Linux 2.4 kernel / filesystem. Signed-off-by: Nick Spence <nick.spence@freescale.com> Acked-by: Bartlomiej Sieka <tur@semihalf.com>
* Restore the ability to continue booting after legacy image overwriteMarian Balakowicz2008-04-17-2/+2
| | | | | | | | | | | Before new uImage code was merged, bootm code allowed for the kernel image to get overwritten during decompresion. new uImage introduced a check for image overwrites and refused to boot the image that got overwritten. This patch restores the old behavior. It also adds a warning when the image overwriten is a multi-image file, because in such case accessing componentes other than the first one will fail.

* [new uImage] Use lmb for bootm allocationsKumar Gala2008-02-29-25/+40
| | | | | | | | | | | | | | | | | | | Convert generic ramdisk_high(), get_boot_cmdline(), get_boot_kbd() functions over to using lmb for allocation of the ramdisk, command line and kernel bd info. Convert PPC specific fdt_relocate() to use lmb for allocation of the device tree. Provided a weak function that board code can call to do additional lmb reserves if needed. Also introduce the concept of bootmap_base to specify the offset in physical memory that the bootmap is located at. This is used for allocations of the cmdline, kernel bd, and device tree as they should be contained within bootmap_base and bootmap_base + CFG_BOOTMAPSZ. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* [new uImage] rework error handling so common functions don't resetKumar Gala2008-02-29-20/+41
| | | | | | | | | | | | | Changed image_get_ramdisk() to just return NULL on error and have get_ramdisk() propogate that error to the caller. It's left to the caller to call do_reset() if it wants to. Also moved calling do_reset() in get_fdt() and fdt_relocate() on ppc to a common location. In the future we will change get_fdt() and fdt_relocate() to return success/failure and not call do_reset() at all.

| | | | | | | | | We don't actually need the kdb param as we are just using it to get bd->bi_memsize which we can get from gd->bd->bi_memsize.

* [new uImage] Correct raw FDT blob handlig when CONFIG_FIT is disabledMarian Balakowicz2008-02-27-6/+12
| | | | | | | | | | | | | | Dual format image code must properly handle all three FDT passing methods: - raw FDT blob passed - FDT blob embedded in the legacy uImage - FDT blob embedded in the new uImage This patch enables proper raw FDT handling when no FIT imaeg support is compiled in. This is a bit tricky as we must dected FIT format even when FIT uImage handling is not enabled as both FIT uImages and raw FDT blobs use tha same low level format (libfdt).

* [new uImage] POWERPC: Add image_get_fdt() routineMarian Balakowicz2008-02-27-32/+44
| | | | | | | | | | FDT blob may be passed either: (1) raw (2) or embedded in the legacy uImage (3) or embedded in the new uImage. For the (2) case embedding image must be verified before we get FDT from it. This patch factors out legacy image specific verification routine to the separate helper routine.

* [new uImage] Move image verify flag to bootm_headers structureMarian Balakowicz2008-02-27-5/+3
| | | | | | | | | | Do not pass image verification flag directly to related routines.

* [new uImage] POWERPC: Split get_fdt() into get and relocate routinesMarian Balakowicz2008-02-27-18/+43
| | | | | | | | | | PPC specific FDT blob handling code is divided into two separate routines: get_fdt() - find and verify a FDT blob (either raw or image embedded) fdt_relocate() - move FDT blob to within BOOTMAP if needed Signed-off-by: Marian Balakowicz <m8@semihalf.com> Acked-by: Kumar Gala <galak@kernel.crashing.org>
* [new uImage] Add dual format uImage support frameworkMarian Balakowicz2008-02-25-47/+131
| | | | | | | | | | | | | | 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>
