Subject: [PATCH 0/4] ppc: memory layout and memtest
Date: Thu, 27 Feb 2014 13:46:55 +0000 [thread overview]
Message-ID: <1393508819-3693-1-git-send-email-renaud.barbier@ge.com> (raw)
This patchset updates the PPC memory layout and memtest:
- Memory regions on PPC are redefined to prevent corruption of critical memory
areas while running the memtest.
- To support the memory test framework with cache disabled, a TLB remapping
function is added for the memtest to enable/disable caching on a mapped
memory region.
- To prevent memtest failure, the memory test is updated to exclude memory
region at the bank start.
Finally, the configuration files are updated for the DA923RC and P2020RDB.
Renaud Barbier (4):
ppc: fix memory layout to prevent corruption during memtest
ppc: add support for memtest with cache disabled
memtest: exclude page starting at address 0.
