You say that, but the ARM925 in OMAP1510 is known not to exhibit the bug in OMAP1610, which causes severe slowdown to DRAM writes when the first address of an STM instruction is not aligned to a d-cache line boundary.  This means that at least last time I looked, the Linux ARM memcpy() implementation is often faster on 1510 than 1610.
