Boot freezing

[AlesRuda]

Hi,

I use Zedboard and I need reserve 32MB of physical memory for FPGA. I set kernel boot param mem=480M. ArchLinux booting process freeze.

Can anybody help me?

I found solution. Problem is in u-boot and implementation of bootm command.
Bootm place fdt outside of memory available for kernel (mem=480M).

Flattened Device Tree blob at 02a00000
Booting using the fdt blob at 0x2a00000
Loading Kernel Image ... OK
Loading Device Tree to 1fb4e000, end 1fb52fcd ... OK

Simple solution is change CONFIG_SYS_SDRAM_SIZE to (480 * 1024 * 1024) in zynq_zed.h and recompile u-boot.
