Subject: [U-Boot-Users] PPC440EPx/sequoia TLB question...
Date: Tue, 22 Apr 2008 22:11:29 -0500	[thread overview]
Message-ID: <480EA8E1.4060207@verizon.net> (raw)

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
