Subject: [PATCH v2 0/5] ARM: Manage the pl310 erratas in a dynamic way
Date: Tue, 29 Jan 2013 15:40:38 +0530 [thread overview]
Message-ID: <20130129101026.GA1063@bnru10> (raw)
This series of patches attempts to manage the pl310 erratas dynamically rather
allowing platforms to choose them during build time.
A bit of information which triggered the cause for this series is here:
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-December/138066.html
v2:
- The commit 74ddcdb868a84f4a9f65e33c1ca0d24e1134e53a
(l2x0: Only set .set_debug on PL310 r3p0 and earlier) which makes the
assumption that non-secure platforms will implement .set_debug interface.
An attempt is made to set .set_debug only if 'smc' is passed either
through DT or through legacy interface (l2x0_init).
With this background, this series adds 'smc' identifier to differentiate
the paltforms which implements SMC interface.
- Use the stashed value instead of reading RTL revision all over the place(Will)
- Added l2x0_quirks to manage the errata in cpu_idle path. Tried to address
Russell's comment on this, but could not completely. Because, neither I can
keep the #ifdef CONFIG_PL310_ERRATA_769419 nor remove it entirely since
the platform A suffers from this bug, whereas B do not but shares the same
defconfig.
srinidhi kasagar (5):
ARM: cache-l2x0: add 'smc' identifier
ARM: cache-l2x0: Manage the errata at run time
ARM: make the platforms not to select the l2x0 erratas
ARM: Handle l2x0 quirks in cpu_idle path
ARM: mach-omap2: apply the errata at run time rather
