The F54 Report Data is apparently read through a fifo and for the smbus protocol that means that between reading a block of 32 bytes the rmiaddr shouldn't be incremented. However, changing that causes other non-fifo reads to fail and so that change was reverted. This patch changes just the F54 function and it now reads 32 bytes at a time from the fifo, using the F54_FIFO_OFFSET to update the start address that is used when reading from the fifo. This has only been tested with smbus, not with i2c or spi. But I suspect that the same is needed there since I think similar problems will occur there when reading more than 256 bytes.
