From 137d105d50f6e6c373c1aa759f59045e6239cf66 Mon Sep 17 00:00:00 2001 From: Santosh Shilimkar Date: Sat, 25 Jun 2011 18:04:31 -0700 Subject: ARM: OMAP4: Fix errata i688 with MPU interconnect barriers. On OMAP4 SOC, intecronnects has many write buffers in the async bridges and they need to be drained before CPU enters into standby state. Patch 'OMAP4: PM: Add CPUX OFF mode support' added CPU PM support but OMAP errata i688 (Async Bridge Corruption) needs to be taken care to avoid issues like system freeze, CPU deadlocks, random crashes with register accesses, synchronisation loss on initiators operating on both interconnect port simultaneously. As per the errata, if a data is stalled inside asynchronous bridge because of back pressure, it may be accepted multiple times, creating pointer misalignment that will corrupt next transfers on that data path until next reset of the system (No recovery procedure once the issue is hit, the path remains consistently broken). Async bridge can be found on path between MPU to EMIF and MPU to L3 interconnect. This situation can happen only when the idle is initiated by a Master Request Disconnection (which is trigged by software when executing WFI on CPU). The work-around for this errata needs all the initiators connected through async bridge must ensure that data path is properly drained before issuing WFI. This condition will be met if one Strongly ordered access is performed to the target right before executing the WFI. In MPU case, L3 T2ASYNC FIFO and DDR T2ASYNC FIFO needs to be drained. IO barrier ensure that there is no synchronisation loss on initiators operating on both interconnect port simultaneously. Thanks to Russell for a tip to conver assembly function to C fuction there by reducing 40 odd lines of code from the patch.

The approach taken in this patch is, AM33XX device will be considered as OMAP3 variant, and a separate SoC class created for AM33XX family of devices with a subclass type for AM335X device, which is newly added device in the family. This means, cpu_is_omap34xx(), cpu_is_am33xx() and cpu_is_am335x() checks will return success on AM335X device. A kernel config option CONFIG_SOC_OMAPAM33XX is added under OMAP3 to include support for AM33XX build. Also, cpu_mask and RATE_IN_XXX flags have crossed 8 bit hence struct clksel_rate.flags, struct prcm_config.flags and cpu_mask are changed to u16 from u8.

This patch moves the knowledge of which platforms have a L2x0 or PL310 cache controller to the individual machines. To enable this, a new MIGHT_HAVE_CACHE_L2X0 config option is introduced to allow machines to indicate that they may have such a cache controller independently of each other. Boards/SoCs which cannot reliably operate without the L2 cache controller support will need to select CACHE_L2X0 directly from their own Kconfigs instead. This applies to some TrustZone-enabled boards where Linux runs in the Normal World, for example.

Most platforms do this (correctly) in the ->reserve callback. However, OMAP has started to call these functions outside of this callback, and this is extremely unsafe - memory will not be unmapped, and could well be given out after memblock is no longer responsible for its management. So, provide arm_memblock_steal() to perform this function, and ensure that it panic()s if it is used inappropriately. Convert everyone over, including OMAP. As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot with this change. Mark this option as BROKEN and make it depend on BROKEN. OMAP needs to be fixed, or 137d105d50 (ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.) reverted until such time it can be fixed correctly.

Since Cortex-A8 and Cortex-A15 have 64-byte cachelines (and it is likely that there will be future ARMv7 implementations with the same line size) then it makes sense to assume that CPU_V7 implies a 64-byte L1 cacheline size. For CPUs with smaller caches, this will result in some harmless padding but will help with single zImage work and avoid hitting subtle bugs with misaligned data structures.
