Hello,

#if defined(CONFIG_XIP_ROM_SIZE)
         /* enable write through caching so we can do execute in place
          * on the flash rom.
          */
         #if defined(CONFIG_TINY_BOOTBLOCK) && CONFIG_TINY_BOOTBLOCK
           #define REAL_XIP_ROM_BASE AUTO_XIP_ROM_BASE
         #else
           #define REAL_XIP_ROM_BASE CONFIG_XIP_ROM_BASE
         #endif
         set_var_mtrr(1, REAL_XIP_ROM_BASE,
CONFIG_XIP_ROM_SIZE,MTRR_TYPE_WRBACK);

#endif

It still hangs at

"Stage: loading
fallback/coreboot_ram @ 0x200000 (360448 bytes), entry @ 0x200000"

for exactly 2min 28sec so I think it speed up a little :).

Thanks I really appreciate your help.

Knut Kujat.
