Agree with you. 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.
