[U-Boot] BeagleBone u-boot bug in arch/arm/include/asm/arch-am33xx/ddr_defs.h

[Matt Thomas]

In arch/arm/include/asm/arch-am33xx/ddr_defs.h:

For the 256MB BeagleBone u-boot initializes the EMIF SDRAM_CONFIG register
with #define MT47H128M16RT25E_EMIF_SDCFG             0x41805332

This is incorrect since it programs a row size of 6 (15 real) where the
MT47H128M16RT25E only had 14 rows [13:0].

It should be using a value of 0x418052B2 (0x41805332 - 0x80) to correctly
address 256MB of RAM instead of the current 512MB.
