This patch makes possible to choose custom byte which should be used to enable non-permanent readout protection (RDP1). Actually, any byte except 0xAA and 0xCC (which are used by RDP0 and RDP2 respectively) can be used to enable RDP1 but in multi-image environment, some other image could check if RDP1 is enabled by comparing it to some hardcoded value. If property is not defined, 0x55 will be used to enable RDP1. The default value comes from STM32 HAL. Signed-off-by: Patryk Duda <pdk@semihalf.com>

This property provides a byte which should used to enable non-permanent
|
|
readout protection (RDP1). Actually, any byte except 0xAA and 0xCC
|
|
(which are used by RDP0 and RDP2 respectively) can be used to enable
|
|
RDP1 but in multi-image environment, some other image could check if
|
|
RDP1 is enabled by comparing it to some hardcoded value. The byte has to
|
|
be different than 0xAA and 0xCC.
