Commit f8c95fe (ARM: imx: support DEBUG_LL uart port selection for all
i.MX SoCs) had a typo that DEBUG_IMX50_IMX53_UART should be
DEBUG_IMX53_UART.

If this option is disabled, you allow userspace (root) access to all

of memory, including kernel and userspace memory. Accidental

access to this is obviously disastrous, but specific access can

be used by people debugging the kernel.

If this option is switched on, the /dev/mem file only allows

userspace access to memory mapped peripherals.

help

When a user program crashes due to an exception, the kernel can
|
|
print a brief message explaining what the problem was. This is
|
|
sometimes helpful for debugging but serves no purpose on a
|
|
production system. Most people should say N here.
|
|
|
|
In addition, you need to pass user_debug=N on the kernel command
|
|
line to enable this feature. N consists of the sum of:
|
|
|
|
1 - undefined instruction events
|
|
2 - system calls
|
|
4 - invalid data aborts
|
|
8 - SIGSEGV faults
|
|
16 - SIGBUS faults
