I tried with macros, but the assembler failed. Can't remember why. But I tried
again a few minutes ago .... and now it works (????).
Do you mean something like this instead?
[...]
#ifdef CONFIG_S3C24XX_NAND_BOOT
# define FORCED_CLOCKS (CLK_RTC | CLK_GPIO | CLK_NAND)
#else
# define FORCED_CLOCKS (CLK_RTC | CLK_GPIO)
#endif
/*
* Disable the clocks for most devices on this chip.
* They will be enabled again on demand
*/
ldr r1, =FORCED_CLOCKS
[...]
