For dra7xx platform the SPL size has been increased to 256KB and hence the existing QSPI SPL partition in kernel (64K size) will break when latest mainline u-boot is used. > Here only SPL partition has been changed and other partition & size is NOT changed and kept intact. I feel it will not break the existing partitions for dra7xx platform. What about the renumbering of partitions in your patch? Probably just best to make the partition information empty in the kernel as discussed.
