* ARM: OMAP4+: Initialize SAR RAM base early for proper CPU1 reset for kexecTony Lindgren2016-06-221-8/+6
| | | | | | | | | | | | | Prepare things for making kexec work on SMP omap variants by initializing SARM RAM base early. This allows us to configure CPU1 for kexec in case the previous kernel has put CPU1 in low power mode. Note that this should not prevent moving other SAR RAM code to live under drivers. However for kexec, we will need this very early. Acked-by: Santosh Shilimkar <ssantosh@kernel.org> Tested-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

| | | | | | | | | | | | | This reverts commit 606da4826b89b044b51e3a84958b802204cfe4c7. We actually need this code for proper behaviour of OMAP4, and it needs fixing a different way other than just removing the code. Disabling code which is necessary in the hopes of persuing multiplatform kernels is a stupid approach.

| * ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688Stefan Hengelein2015-03-161-69/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Kconfig-Option OMAP4_ERRATA_I688 is never visible due to a contradiction in it's dependencies. The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be enabled. These options inherit a dependency from an enclosing menu, that requires ARCH_MULTIPLATFORM to be 'enabled'. This is a contradiction and made this option also unavailable for non-multiplatform configurations. Since there are no selects on OMAP4_ERRATA_I688, which would ignore dependencies, the code related to that option is dead and can be removed. This (logical) defect has been found with the undertaker tool.

This patch does just this, updating the DT files to actually reflect what the HW provides. BIG FAT WARNING: because the DTs were so far lying by not exposing the WUGEN HW block, kernels with this patch applied won't have any suspend-resume facility when booted with old DTs, and old kernels with updated DTs won't even boot.

* | ARM: OMAP: Work around hardcoded interruptsMarc Zyngier2015-01-171-0/+32
|/ | | | | | | | | | | | | | | | | | | | | | | | Commit 9a1091ef0017 ("irqchip: gic: Support hierarchy irq domain") changed the GIC driver to use a non-legacy IRQ domain on DT platforms. This patch assumes that DT-driven systems are getting all of their interrupts from device tree. Turns out that OMAP has quite a few hidden gems, and still uses hardcoded interrupts despite having fairly complete DTs. This patch attempts to work around these by offering a translation method that can be called directly from the hwmod code, if present. The same hack is sprinkled over PRCM and TWL. It isn't pretty, but it seems to do the job without having to add more hacks to the interrupt controller code. Tested on OMAP4 (Panda-ES) and OMAP5 (UEVM5432).

* ARM: OMAP2+: l2c: squelch warning dump on power control settingSekhar Nori2014-07-141-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | On OMAP SOCs using PL310 controllers, power_ctrl register is not accessible from non-secure software even on PL310 versions which support it. The secure code takes care of setting it up correctly and power transitions are proven on these devices. For example, AM437x has L2C-310 version r3p3 and ROM code on that device does not support writing to L2C-310 power control register. The L2C driver, however, tries writing to this register for all revisions >= r3p0. This leads to a warning dump on boot which leads most users to believe that L2 cache is non-functional. Since the problem is understood, and cannot be addressed through software, replace the warning with a pr_info() while maintaining the WARN_ON() for other truly unexpected scenarios.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Kexec disables outer cache before jumping to reboot code, but it doesn't flush it explicitly. Flush is done implicitly inside of l2x0_disable(). But some SoC's override default .disable handler and don't flush cache. This may lead to a corrupted memory during Kexec reboot on these platforms. This patch adds cache flush inside of OMAP4 and Highbank outer_cache.disable() handlers to make it consistent with default l2x0_disable().
