Adrian Freihofer <adrian.freihofer@siemens.com>\n\ni.MX8QXP rev C.0 requires boot container stored at offset 0KB\nfor eMMC, while i.MX8QXP pre C.0 requires boot container stored\nat offset 32KB for eMMC.\n\nTo use one U-Boot binary to support different chip revisions,\nintroduce fb_mmc_get_boot_offset() to allow override the default\noffset when writing to eMMC boot partitions.\n\nThis enables support for devices with non-standard boot partition\nlayouts, such as those requiring an offset for correct bootloader\nplacement.\n\nSigned-off-by: Adrian Freihofer
