Enabled.

It is the default config, there is an extra bit of code for Linux
emulation that will change the kernel size a bit but it isn't being
called at this stage in startup.

Your board:

sdram_config = 0x30ed, memsize = 2048MB

My board:

sdram_config = 0x30e3, memsize = 512MB

If I force memsize to 0x80000000 in awin_memprobe() then it boots.

This version of u-boot boots Linux fine and uses the correct amount of
RAM.
