SA1100 flash: CFI device at 0x00000000, 32MiB, 32-bit
Creating 3 MTD partitions on "sa1100":

0x0000001c0000-0x000000fe0000 : "rootfs"
Is the upperword chip D-16-31 not responding ? Why this strange answer?
Finally, the iomap of this device based on sa1100: seems originally
intended for 32MB but there are only 16 onboard and that seems causing
the alias at 0x1000000
372 static struct map_desc collie_io_desc[] __initdata = {
373 { /* 32M main flash (cs0) */
374 .virtual = 0xe8000000,
375 .pfn = __phys_to_pfn(0x00000000),
376 .length = 0x02000000,
377 .type = MT_DEVICE
378 }, { /* 32M boot flash (cs1) */
379 .virtual = 0xea000000,
380 .pfn = __phys_to_pfn(0x08000000),
381 .length = 0x02000000,
382 .type = MT_DEVICE
383 }
384 };
Worth to resize it?
Thanks in advance for your attention
Cheers
Andrea
