LCD-driver: head.S:582: Error: Illegal operands



 
Hi everybody, 
 
I followed instructions in the document "How to write Device Driver for
Linux", but 
I cannot compile kernel correctly. I would appreciate any idea what should I 
check out? Well, at least connecting the lcd-display should be not too
difficult 
task according to circuit diagrams found in literature and internet. 
 
In axis/devboard_lx/os/linux I have made menuconfig and enabled "LCD 
(HD44780) Support". 
Parallel port support is deactivated. 
 
in /axis/devboard_lx/ directory I have made 
 
make tools 
make kernel 
 
after that I get error messages: 
 
-mlinux -nostdlib  -r -o kernel.o process.o signal.o entry.o traps.o
irq.o ptrace.o 
setup.o time.o sys_cris.o shadows.o debugport.o semaphore.o 
/usr/local/cris/lib/gcc-lib/cris/2.96/gcc -D__ASSEMBLY__ -D__KERNEL__ 
-I/home/jarmova/axis/devboard_lx/os/linux/include -mlinux -c head.S -o head.o 
head.S: Assembler messages: 
head.S:582: Error: Illegal operands

Here is the part head.S file : 
 
#if defined(CONFIG_ETRAX_PARALLEL_PORT0) || \ 
     defined(CONFIG_ETRAX_ETHERNET_LPSLAVE) || \ 
     defined(CONFIG_ETRAX_LCD_HD44780) 
        or.w    0x4,r0  ; parport 0 enabled using DMA 2/3 
#endif 
#if defined(CONFIG_ETRAX_PARALLEL_PORT1) || 
defined(CONFIG_ETRAX_ETHERNET_LPSLAVE) 
	; parport 1 enabled using DMA 4/5 
	or.w	IO_STATE (R_GEN_CONFIG, par1, select),$r0 
#endif 
 
#ifdef CONFIG_ETRAX_IDE  /*** THE LINE 582  ***/ 
	; DMA channels 2 and 3 to ATA, ATA enabled 
	or.d	  IO_STATE (R_GEN_CONFIG, dma3, ata)	\ 
		| IO_STATE (R_GEN_CONFIG, dma2, ata)	\

#endif 
 
What I am missing?
