AM6526: Is ECC Data Bit Swapping allowed as well ?

Hi,

My customer is now designing their board based on AM6526 with DDR3L. According to the SPRACI2A “AM65x/DRA80xM DDR Board Design and Layout Guidelines”, they understood that Data bit swapping is allowed, provided the bits swapped are within the same byte group. However, the prime bit, the lowest numbered bit in each byte, must be connected to the corresponding bit on the SDRAM without swapping.

Is it possible to swap ECC bit DDR_ECC_D[6:0] as well ?
