Memtest failed. Error: -22
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.
Renaud.

Thanks for noting, this is worth fixing. I think though that we can wait until you are back.
