I just used memtest on a couple of PPC board (freescale mpc8544 and P1014) and it failed with: barebox>/ memtest Memtest failed. Error: -22 This error happens when the space between two regions is smaller than a page size: 0x0bf75000 - 0x0ff74fff (size 0x04000000) malloc space 0x0ff756e8 - 0x0ff7d6e7 (size 0x00008000) stack In this case, the size - when doing the calculation "size = PAGE_ALIGN_DOWN(end - start + 1);" - is zero. The function call ret = alloc_memtest_region(list, start, size); then fails. I will not be able to offer a patch until second week of June as I am away.
