[U-Boot] [PATCH 1/2][v2] powerpc/mpc85xx: SECURE BOOT- add version info for ISBC

[Aneesh Bansal]

T4/B4 SoC's have a different version of ISBC. The secure boot
functionality is different with the new version of ISBC
compared to the earlier SoC's. So the version information is added
in file config_mpc85xx.h

[U-Boot] [PATCH 1/2][v2] powerpc/mpc85xx: SECURE BOOT- add version info for ISBC

[Wolfgang Denk]

Dear Aneesh Bansal,

In message <1390203451-8561-1-git-send-email-aneesh.bansal@freescale.com> you wrote:

Same comment as V1:  please do not define new CONFIG options without
need.

Best regards,

Wolfgang Denk
