How to enable LS1046a ITS bit in u-boot environment ?

[Jeffrey_Lai]

Hi,

We try to enable LS1046 secure boot.

According to LSDK user manual, program SRKH and OPTMK in u-boot CLI environment is OK but program ITS bit is failed.

The command as below.

#program SRKH and OPTMK

mw.l 0x1e80234 0x...
mw.l 0x1e80238 0x...

...

mw.l 0x1e80250 0x...

mw.l 0x1e80254 0x...
mw.l 0x1e80258 0x...
...
mw.l 0x1e80270 0x...

#program ITS

mw.l 0x1e80200 0x4

mw.l 0x1e80020 0x02000000

Is it correct and how to set ITS bit in u-boot CLI environment ?
