SDRAM change from 64MB to 128MB

1. Nboot change
change
1.1 MEMC_TYPE to 32x16 ,mobil dram
1.2 PWR_DELAY_CTRL0 and PWR_DELAY_CTRL1
in D:\WINCE500\PLATFORM\MGPS\Nboot\sdram32.s
2. CE change
To change SDRAM size to 128M, we need to change the following files:
2.1. ATLASII_HH.BAT : SET DRAM_128M=1
2.2.\WINCE500\PLATFORM\ARAGORN\FILES\CONFIGCE.BIB
Change the Dram Size to fit the 128M usage - 0x073B0000(128M) = 0x033B0000(64M) + 0x4000000
IF DRAM_128M=1

#define FREE_RAMSIZE 073B0000
ELSE
#define FREE_RAMSIZE 033B0000

ENDIF
2.3.\WINCE500\PLATFORM\ARAGORN\INC\ARMMAP.INC
Change the DRAM_SIZE to 128M
DCD 0x8C000000, 0xC0000000, 128 ; 128 MB SDRAM
