| * ARM: i.MX: bbu: support partitions starting at i.MX headerSascha Hauer2018-07-022-2/+13
| | | | | | | | | | | | | | | | The i.MX header is at an offset in the boot device, usually 0x400 bytes. This patch adds a flag to support the case that the partition the image is written to starts at that offset rather than 0x0. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * ARM: i.MX: bbu: reimplement IMX_INTERNAL_FLAG_KEEP_DOSPART flagSascha Hauer2018-07-022-45/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch reimplements the IMX_INTERNAL_FLAG_KEEP_DOSPART flag and makes it more generic. Until now we only kept a dos partition table over the update. Beginning with i.MX8 we may also want to preserve a GPT, so we have to extend the preserved area. It might also be the case that not (only) a partition table is stored in the initial area of a device, but also other unrelated data, so it's better to just keep the initial area that is unused by the i.MX ROM. It's also good to export the flag to allow boards to specify the initial area shall be preserved. When a board wants to set the flag for a mtd like device then it has to check for suitable erase sizes beforehand. We do not check this (yet). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | It is not always desired to get the devicetree from image data and load it to a SDRAM region at the same time. Sometimes it's enough to just load it to an allocated address (in case the user has no constraints where the devicetree should be placed. This patch splits bootm_load_devicetree into bootm_get_devicetree which returns a pointer to the allocated devicetree and bootm_load_devicetree which loads the devicetree to a specified region.
