* OMAP2/3: Add omap_type() for determining GP/EMU/HSKevin Hilman2009-06-23
| | | | | | | | | | | | | | | The omap_type() function is added and returns the DEVICETYPE field of the CONTROL_STATUS register. The result can be used for conditional code based on whether device is GP (general purpose), EMU or HS (high security). Also move the type defines so omap1 code compile does not require ifdefs for sections using these defines. This code is needed for the following fix to set the SRAM size correctly for HS omaps. Also at least PM and watchdog code will need this function. Signed-off-by: Kevin Hilman <khilman@ti.deeprootsystems.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

* OMAP1: Fix N770 MMC supportAndrew de Quincey2009-06-23
| | | | | | | | | | | | | | | | Some of the N770's MMC configuration options seem to have been dropped. This patch adds them back in again. Note that only the .ocr_mask change was /critical/, but I've added the .max_freq setting back as well, as the original sources had it. Can anyone confirm if this is unnecessary? Secondly, there is support in the original code for a 4wire/higher speed mode. As I don't have the requisite N770 hardware (I think it was a rev2 N770?) to test this, I can't really add it back.

| * Blackfin: fix dma-mapping build errorsFUJITA Tomonori2009-06-22
| | | | | | | | | | | | | | | | | | | | The recent deprecation of dma_sync_{sg,single} ironically broke Blackfin systems. This is because we don't define dma_sync_sg_for_cpu at all, so until the DMA asm-generic conversion/cleanup is done after the next release, simply stub out the dma_sync_sg_for_{cpu,device} functions.

| | | | | | | | | | | | | | | | | | | | Make sure we process the kernel command line before poking the hardware, so that we can process early printk.

| * Blackfin: unify memory map headersMike Frysinger2009-06-22
| | | | | | | | | | | | | | | | | | | | Many aspects of the Blackfin memory map is exactly the same across all variants. Rather than copy and paste all of these duplicated values in each header, unify all of these into the common Blackfin memory map header file. In the process, push down BF561 SMP specific stuff to the BF561 specific header to keep the noise down. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
| * Blackfin: stick the CPU name into boot image nameRobin Getz2009-06-22
| | | | | | | | | | | | | | | | | | | | | | Rather than use "Linux" in the boot image name (as this is redundant -- the image type is already set to "linux"), use the CPU name. This makes it fairly obvious when a wrong image is accidentally booted. Otherwise there is no kernel output and you waste time scratching your head wondering wtf just happened.

| * Blackfin: decouple unrelated cache settings to get exact behaviorJie Zhang2009-06-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current cache options don't really represent the hardware features. They end up setting different aspects of the hardware so that the end result is to turn on/off the cache. Unfortunately, when we hit cache problems with the hardware, it's difficult to test different settings to root cause the problem. The current settings also don't cleanly allow for different caching behaviors with different regions of memory. So split the configure options such that they properly reflect the settings that are applied to the hardware.

| * Blackfin: fix accidental reset in some boot modesSonic Zhang2009-06-22
| | | | | | | | | | | | | | | | | | | | | | | | We read the SWRST (Software Reset) register to get at the last reset state, and then we may configure the DOUBLE_FAULT bit to control behavior when a double fault occurs. But if the lower bits of the register is already set (like UART boot mode on a BF54x), we inadvertently make the system reset by writing to the SYSTEM_RESET field at the same time. So make sure the lower 4 bits are always cleared. Signed-off-by: Sonic Zhang <sonic.zhang@analog.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

| * Blackfin: redo handling of bad irqsMike Frysinger2009-06-22
| | | | | | | | | | | | | | | | | | | | With the common IRQ code initializing much more of the irq_desc state, we can't blindly initialize it ourselves to the local bad_irq state. If we do, we end up wrongly clobbering many fields. So punt most of the bad irq code as the common layers will handle the default state, and simply call handle_bad_irq() directly when the IRQ we are processing is invalid.

| | | | | | | | | | | | | | | | | | The kgdb (in multiple places) and traps code developed pretty much identical checks for how to access different regions of the Blackfin memory map, but each wasn't 100%, so unify them to avoid duplication, bitrot, and bugs with edge cases.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The patch adds kernel parameter intel_iommu=pt to set up pass through mode in context mapping entry. This disables DMAR in linux kernel; but KVM still runs on VT-d and interrupt remapping still works. In this mode, kernel uses swiotlb for DMA API functions but other VT-d functionalities are enabled for KVM. KVM always uses multi level translation page table in VT-d. By default, pass though mode is disabled in kernel. This is useful when people don't want to enable VT-d DMAR in kernel but still want to use KVM and interrupt remapping for reasons like DMAR performance concern or debug purpose.
