[U-Boot-Users] PPC440EPx/sequoia TLB question...

[Dave Littell]

Hi all,

>From …/board/amcc/sequoia/init.S:

/* TLB-entry for Internal Registers & OCM */
tlbentry( 0xe0000000, SZ_16M, 0xe0000000, 0, AC_R|AC_W|AC_X|SA_I )

Why is this memory region not marked Guarded?  It would seem to meet the
definition of “non-well-behaved”.

Also the TLB entry for SDRAM marks it Guarded, but that’s one area I
would think wouldn't need to be Guarded.


Thanks,
Dave
