With OMAP3530 on BeagleBoard we like to read OMAP3's CONTROL_RAND_KEY_0 (0x4800 2318) register with something like printf ("attempting cpu_uid read\n"); u32 cpu_uid = *((u32 *) 0x48002318); /* u32 cpu_uid = readl(&ctrl_base->randkey_0); */ printf ("cpu_uid read done\n");This address is not accessible out side of secure mode along with some other qualifiers. Trying to access is futile and will result in an abort. The control register range is full of readable and aborting addresses.
Is there any hint in TRM (spruf98b.pdf) identifying/marking which registers are readable in normal and which are only accessible in secure mode?
