11 * The GENIETV is using the following physical memorymap (copied from
12 * the FADS configuration):
13 *
14 * ff020000 -> ff02ffff : pcmcia
15 * ff010000 -> ff01ffff : BCSR connected to CS1, setup by 8xxROM
16 * ff000000 -> ff00ffff : IMAP internal in the cpu
17 * 30000000 -> 300fffff : flash connected to CS0
18 * 00000000 -> nnnnnnnn : sdram setup by U-Boot
19 *
20 * CS pins are connected as follows:
21 *
22 * CS0 -512Kb boot flash
23 * CS1 - SDRAM #1
24 * CS2 - SDRAM #2
25 * CS3 - Flash #1
26 * CS4 - Flash #2
27 * CS5 - Lon (if present)
28 * CS6 - PCMCIA #1
29 * CS7 - PCMCIA #2
