Hi
I looked into the documentation but I can't find a command which copies an image from one address to another. This would be extremly useful for me as reading from (uncached) flash is way slower then reading from cached SDRAM. Currently booting is done by a simple bootm. This requires that the image is read from flash twice (once for checksum and once for decompression) If the image is copied to DRAM first it has to be read from flash only once. Checksum calculation and decompression is done in SDRAM which saves me about 500ms on my system. A further optimization would be to do the checksum calculation while copying the image to SDRAM which would save some more ms.
So, if there is no such command I am willing to implemt 'imcpy'.
