XIP kernel(2.6.11 with MTD) fail in compiling

[Chen,Xi]

Hello,

I'm working on a PXA-272 based development board and trying to enable a 
XIP kernel for it.
The root file system needs to be JFFS2, so MTD support should be 
included. When I tried to
boot the kernel, it stalled at that message:
===============================================
......
eth0: cs8900 rev K found at 0xf0000300 no EEPROM
cs89x0: No EEPROM, relying on command line....
cs89x0 media RJ-45, IRQ 41, programmed I/O, MAC 00:0b:f4:2f:9b:e5
Probing flash0 at physical address 0x00000000 (32-bit bankwidth)
===============================================

I found an option in kernel configuration, named "MTD_XIP" and it seemed 
a solution.
I also added a "-mlong-calls" option to CFLAGS when XIP enabled, in case 
some function
calls exceeded the PC24 limitation in ARM.
Compilation errors occured like that:

===============================================

Anyone knows why the linker still complains, even with "-mlong-calls" used?

My cross compile toolchain versions:
arm-linux-gcc 3.4.3
binutils 2.16
And some basic info about my memory layout:
flash memory start from 0x00000000, 64MB
SDRAM start from 0xa0000000, 64MB

Thanks a lot for your time.
