This is for 2.5.1.0 of DS1000E.

It seems each "module" is separate in the firmware upgrade file, with one ZEROFILL after each code one (if BSS data is needed.)
The only INIT block contains the same bytes as the one preceding it.
- It initializes settings for SDRAM.
  - EBIU_SDRRC = 0x0FFF
  - EBIU_SDBCTL = 0x11 (EBE | EBSZ_16MB | EBCAW_9BITS)
  - EBIU_SDGCTL = 0x0091998D
  - EBIU_AMGCTL = 4 (AMBEN_0_1)
Things up to 0x0800 0000 are in SDRAM.
0xFF80 6000 – 0xFF80 8000 are in Data bank A SRAM
0xFFA0 8000 and up is Instruction SRAM
