* ARM: Introduce erratum workaround for 801819Nishanth Menon2015-08-121-0/+21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add workaround for Cortex-A15 ARM erratum 801819 which says in summary that "A livelock can occur in the L2 cache arbitration that might prevent a snoop from completing. Under certain conditions this can cause the system to deadlock. " Recommended workaround is as follows: Do both of the following: 1) Do not use the write-back no-allocate memory type. 2) Do not issue write-back cacheable stores at any time when the cache is disabled (SCTLR.C=0) and the MMU is enabled (SCTLR.M=1). Because it is implementation defined whether cacheable stores update the cache when the cache is disabled it is not expected that any portable code will execute cacheable stores when the cache is disabled. For implementations of Cortex-A15 configured without the “L2 arbitration register slice” option (typically one or two core systems), you must also do the following: 3) Disable write-streaming in each CPU by setting ACTLR[28:25] = 0b1111 So, we provide an option to disable write streaming on OMAP5 and DRA7. It is a rare condition to occur and may be enabled selectively based on platform acceptance of risk. Applies to: A15 revisions r2p0, r2p1, r2p2, r2p3 or r2p4 and REVIDR[3] is set to 0. Note: certain unicore SoCs *might* not have REVIDR[3] not set, but might not meet the condition for the erratum to occur when they donot have ACP (Accelerator Coherency Port) hooked to ACE (AXI Coherency Extensions). Such SoCs will need the work around handled in the SoC specific manner, since there is no ARM generic manner to detect such configurations.

* ARM: cache: implement a default weak flush_cache() functionWu, Josh2015-08-125-60/+5
| | | | | | | | | | | | | | | | | Current many cpu use the same flush_cache() function, which just call the flush_dcache_range(). So implement a weak flush_cache() for all the cpus to use. In original weak flush_cache() in arch/arm/lib/cache.c, there has some code for ARM1136 & ARM926ejs. But in the arch/arm/cpu/arm1136/cpu.c and arch/arm/cpu/arm926ejs/cache.c, there implements a real flush_cache() function as well. That means the original code for ARM1136 & ARM926ejs in weak flush_cache() of arch/arm/lib/cache.c is totally useless. So in this patch remove such code in flush_cache() and only call flush_dcache_range(). Signed-off-by: Josh Wu <josh.wu@atmel.com>

* LG Optimus Black (P970) codename sniper supportPaul Kocialkowski2015-08-121-0/+8
| | | | | | | | | | | | | | | | | | | | The LG Optimus Black (P970) codename sniper is a smartphone that was designed and manufactured by LG Electronics (LGE) and released back in 2011. It is using an OMAP3630 SoC GP version, which allows running U-Boot and the U-Boot SPL from the ground up. This port is aimed at running an Android version such as Replicant, the fully free Android distribution. However, support for upstream Linux with device-tree and common GNU/Linux distros boot commands could be added in the future.

| | | | | | | | | | | | | | | | | | | | | The change adds support of LPC32xx SLC NAND controller. LPC32xx SoC has two different mutually exclusive NAND controllers to communicate with single and multiple layer chips. This simple driver allows to specify NAND chip timings and defines custom read_buf()/write_buf() operations, because access to 8-bit data register must be 32-bit aligned. Support of hardware ECC calculation is not implemented (data correction is always done by software), since it requires a working DMA engine. The driver can be included to an SPL image.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | USB devices are not really designed to get the power bounced off and on at them. Esp. USB powered harddisks do not like this. Currently we power off the USB ports both on a "usb reset" and when booting the kernel, causing the usb-power to bounce off and then back on again. This patch removes the powering off calls, fixing the undesirable power bouncing. Note this requires some special handling for the OTG port: 1) We must skip the external vbus check if we've already enabled our own vbus to avoid false positives 2) If on an usb reset we no longer detect that the id-pin is grounded, turn off vbus as that means an external vbus may be present now Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>
