Just to clarify: this file has the RAM settings for two versions of
the board. Earlier mx35pdk came with mDDR and the more recent boards
have DDR2. Most likely your mx35pdk has DDR2 populated, do the values
you need to use are:

//DDR2 init
DCDGEN(2, 4, 0xB8001010, 0x00000304)
DCDGEN(3, 4, 0xB8001010, 0x0000030C)
DCDGEN(4, 4, 0xB8001004, 0x007ffc3f)
DCDGEN(5, 4, 0xB8001000, 0x92220000)
DCDGEN(6, 4, 0x80000400, 0x12345678)
DCDGEN(7, 4, 0xB8001000, 0xA2220000)
DCDGEN(8, 4, 0x80000000, 0x87654321)
DCDGEN(9, 4, 0x80000000, 0x87654321)
DCDGEN(10, 4, 0xB8001000, 0xB2220000)
DCDGEN(11, 1, 0x80000233, 0xda)
DCDGEN(12, 1, 0x82000780, 0xda)
DCDGEN(13, 1, 0x82000400, 0xda)
DCDGEN(14, 4, 0xB8001000, 0x82226080)
DCDGEN(15, 4, 0xB8001004, 0x007ffc3f)
DCDGEN(16, 4, 0xB800100C, 0x007ffc3f)
DCDGEN(17, 4, 0xB8001010, 0x00000304)
DCDGEN(18, 4, 0xB8001008, 0x00002000)

You just need to convert these values into the proper syntax for imximage.cfg.
