The Compal E88 has the following physical memory map:

    /* 2 MBytes of external flash memory */
    FLASH (rx) : ORIGIN = 0x00000000, LENGTH = 0x200000
    /* 256 kBytes of internal zero-waitstate sram */
    IRAM  (rw) : ORIGIN = 0x00800000, LENGTH = 0x040000
    /* 256 kBytes of external slow sram */
    ERAM  (rw) : ORIGIN = 0x01000000, LENGTH = 0x040000

The flash layout, as distributed, is:

    0x00000000 0x2000 Compal loader
    0x00002000 >>>>>> Compal application and storage

Our flash layout is:

    0x00000000 0x2000 Compal loader
    0x00002000 0xE000 OSMOCOM loader (see LINKAGE.txt for reasoning)
    0x00010000 >>>>>> OSMOCOM application and storage

(XXX: determine storage location / storage descriptor location)
