FB_PIN_CTL
RW
1
Determines toggling a GPIO pin at the start and end of
Flash boot
2 = Enable toggling a GPIO pin at the start and end of
Flash boot
Others = Disable toggling a GPIO pin at the start and
end of Flash boot
Default value = 1.
2:3
FB_RSA3K_CTL
RW
1
Determines if RSA-3K is supported.
2 = RSA-3K is supported. RSA public key modulo
length should be in range 512 to 3072 bit. The field
FB_RSA4K_CTL must be set to 0.
Others = RSA-3K is not supported. RSA public key
modulo length should be in range 512 to 2048 bit.
Default value = 1.
4:5
FB_RSA4K_CTL
RW
1
Determines if RSA-4K is supported.
2 = RSA-4K is supported. RSA public key modulo
length should be in range 512 to 4096 bit. RSA4K
already includes RSA3K option. The field
FB_RSA3K_CTL must be set to 0.
Others = RSA-4K is not supported.
Default value = 1.
