Commit 83d26d1113d8 ("ARM: 7824/1: update advice on kernel, initramfs and FDT load address.") changed the offset requirement for loading a raw kernel image into RAM from 32KiB (0x8000) to TEXT_OFFSET - PAGE_OFFSET, which results in a negative value. Change the offset to be TEXT_OFFSET, which has an arch dependent value between 0x8000 and 0x308000.
