Subject: [U-Boot] NOR sectors are not all protected as they should be.

Hello,
I'm using U-Boot with a NOR and a NAND Flash.
U-Boot is stored into the NOR flash.
The NOR flash is setup as :
0xA0000000 -> 0xA0080000 -> 512k -> 8 sectors -> reserved for U-Boot.bin
0xA0080000 -> 0xA00A0000 -> 128k -> 2 sectors -> reserved for U-Boot
environment
If I use the command `flinfo` to see which sectors are protected I see
this...

The first sectors #0,1,2,3 are protected and sectors #8,9 (U-Boot
environment) are protected.
It should be sectors #0,1,2,3,4,5,6,7 and sectors #8,9.
I had a looked into U-Boot source to find a constant that defines how
many sectors should be protected for the monitor but I didn't find it.
I guess U-Boot protect these sectors during the boot sequence.
What constant must be defined to protect all of the sectors
(#0,1,2,3,4,5,6,7) ?
thanks in advance.
Alex
