4、 中断部分修改
2410的datasheet上，INTSUBMSK有11位可用，而2440的INTSUBMSK有15位可用
# ifdefined(CONFIG_S3C2410)
ldr r1, =0x3ff
ldr r0, =INTSUBMSK
str r1, [r0]
# endif
修改为
# ifdefined(CONFIG_S3C2410)
ldr r1, =0x7ff
ldr r0, =INTSUBMSK
str r1, [r0]
# endif
# ifdefined(CONFIG_S3C2440)
ldr r1, =0x7fff
ldr r0, =INTSUBMSK
str r1, [r0]
# endif
5、 时钟部分修改
/* FCLK:HCLK:PCLK = 1:2:4 */
/* default FCLK is 120 MHz ! */
ldr r0, =CLKDIVN
mov r1, #3
str r1, [r0]
#endif /* CONFIG_S3C2400 || CONFIG_S3C2410 ||CONFIG_S3C2440*/
修改为
#ifdefined(CONFIG_S3C2440)
/* FCLK:HCLK:PCLK = 1:4:8 */
ldr r0, =CLKDIVN
mov r1, #5
str r1, [r0]
mrc p15, 0, r1, c1, c0, 0
orr r1, r1, #0xc0000000
mrc p15, 0, r1, c1, c0, 0
mov r1, #CLK_CTL_BASE
mov r2, #MDIV_405
add r2, r2, #PSDIV_405
str r2, [r1, #0x04]
#else
/* FCLK:HCLK:PCLK = 1:2:4 */
/* default FCLK is 120 MHz ! */
ldr r0, =CLKDIVN
mov r1, #3
str r1, [r0]
mrc p15, 0, r1, c1, c0, 0
orr r1, r1, #0xc0000000
mrc p15, 0, r1, c1, c0, 0
mov r1, #CLK_CTL_BASE
mov r2, #MDIV_200
add r2, r2, #PSDIV_200
str r2, [r1, #0x04]
#endif
#endif /* CONFIG_S3C2400 || CONFIG_S3C2410 ||CONFIG_S3C2440*/
