2008-02-29[new uImage] rework error handling so common functions don't resetKumar Gala
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.

2008-02-29[new uImage] ppc: Re-order ramdisk/fdt handling sequenceKumar Gala
Doing the fdt before the ramdisk allows us to grow the fdt w/o concern however it does mean we have to go in and fixup the initrd info since we don't know where it will be. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-02-29[new uImage] ppc: Determine if we are booting an OF styleKumar Gala
If we are bootin OF style than we can skip setting up some things that are used for the old boot method. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Marian Balakowicz <m8@semihalf.com>
2008-02-29[new uImage] Don't pass kdb to ramdisk_high since we may not have oneKumar Gala
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. Also, if we boot via OF we might not actually fill out a kdb. Signed-off-by: Kumar Gala <galak@kernel.crashing.org> Acked-by: Marian Balakowicz <m8@semihalf.com>
2008-02-27[new uImage] Correct raw FDT blob handlig when CONFIG_FIT is disabledMarian Balakowicz
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). Signed-off-by: Marian Balakowicz <m8@semihalf.com>
2008-02-27[new uImage] POWERPC: Add image_get_fdt() routineMarian Balakowicz
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. Signed-off-by: Marian Balakowicz <m8@semihalf.com> Acked-by: Kumar Gala <galak@kernel.crashing.org>
2008-02-27[new uImage] Move image verify flag to bootm_headers structureMarian Balakowicz
Do not pass image verification flag directly to related routines. Simplify argument passing and move it to the bootm_header structure which contains curently processed image specific data and is already being passed on the argument list.

2008-02-27[new uImage] POWERPC: Split get_fdt() into get and relocate routinesMarian Balakowicz
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>
2008-02-25[new uImage] Add dual format uImage support frameworkMarian Balakowicz
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>

2008-02-07[new uImage] Rename architecture specific bootm code filesMarian Balakowicz
