The patches in this series address an issue I met when trying to enable FIT signature verification by SPL on a RockPi4B board.
- The first patch avoids a buffer overflow when writing to INTMEM1 SRAM - The second one addresses reliability issues I had with back-to-back MMC reads from the microSD card. By allowing DMA operation, the issue is gone and generally speaking DMA is preferred over FIFO mode anyways.
