Sorry, no. The flash chips are 0xf800-0xf9ff (32MB). (Actually we have
twice this area reserved for 64MB flash in the future). The flash chip from
0xf800 is also mirrored at 0xfff0 at boot time. I don't know if you
consider this a hardware bug to not have all the flash at the ve

Hmmm. 2 * 16MByte, thats 32MByte == 0x200. So you should have one chip
at base address 0xff00 and one at 0xfe
Yes we do have 2 flash chips. Here's the mapping:
#define CONFIG_SYS_FLASH_BASE 0xf800 /* 2 chips*16M */
#define CONFIG_SYS_MONITOR_BASE TEXT_BASE /* start of monitor */
and in our config.mk file:
TEXT_BASE = 0xfff4
This is the same flash chip as that at 0xf800, but remap

Just to be sure
Our hardware has part of the flash mapped in two address ranges.
The CONFIG_SYS_MONITOR_BASE is in the upper 'boot' area, whereas
the CONFIG_SYS_FLASH_BANKS_LIST has the full flash available at
a lower address.
This all works fine until the code in cfi_flash.c:flash_init(), which
uses flash_get_in
