Hello all

There's a 0x40 byte u-boot header preceeding the kernel image. Loading it at
0x79C0 will thus place the kernel entry point at 0x8000.
You can load the kernel elsewhere, but then u-boot will have to memcpy the
kernel image to 0x8000 before booting it. This increases the boot time.
On the zynq, the effect isn't quite as noticable, but on weaker CPUs with
slower memory, loading the kernel at the right spot can gain about a hundred
milliseconds or more.
That may not sound like much, but on a total boot time of less than 5 seconds,
100 ms is 2%...
Mike.
I was having same problem
Also see meta-topic meta-topic/recipes-bsp/bootscripts/
Hope this helps.
