* x86/mid: Remove Intel MoorestownAlan Cox2012-01-26
| | | | | | | | | | | | All production devices operate in the Oaktrail configuration with legacy PC elements present and an ACPI BIOS. Continue stripping out the Moorestown elements from the tree leaving Medfield.

| | | | | | | | | | | | | | | Moorestown platform doesn't have a m146818 RTC device like traditional x86 PC, but a firmware emulated virtual RTC device(vrtc), which provides some basic RTC functions like get/set time. vrtc serves as the only wall clock device on Moorestown platform.

* x86/mrst: Add SFI platform device parsing codeFeng Tang2010-11-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SFI provides a series of tables. These describe the platform devices present including SPI and I²C devices, as well as various sensors, keypads and other glue as well as interfaces provided via the SCU IPC mechanism (intel_scu_ipc.c) This patch is a merge of the core elements and relevant fixes from the Intel development code by Feng, Alek, myself into a single coherent patch for upstream submission. It provides the needed infrastructure to register I2C, SPI and platform devices described by the tables, as well as handlers for some of the hardware already supported in kernel. The 0.8 firmware also provides GPIO tables. Devices are created at boot time or if they are SCU dependant at the point an SCU is discovered. The existing Linux device mechanisms will then handle the device binding. At an abstract level this is an SFI to Linux device translator. Device/platform specific setup/glue is in this file. This is done so that the drivers for the generic I²C and SPI bus devices remain cross platform as they should.

* x86, earlyprintk: Add hsu early console for Intel Medfield platformFeng Tang2010-10-08
| | | | | | | | | | | | | | | Intel Medfield platform has a high speed UART device, which could act as a early console. To enable early printk of HSU console, simply add "earlyprintk=hsu" in kernel command line. Currently we put the code in the early_printk_mrst.c as it is also for Intel MID platforms like the mrst early console Signed-off-by: Feng Tang <feng.tang@intel.com> Acked-by: Alan Cox <alan@linux.intel.com> Cc: greg@kroah.com LKML-Reference: <1284361736-23011-5-git-send-email-feng.tang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
* x86, earlyprintk: Add earlyprintk for Intel Moorestown platformFeng Tang2010-10-08
| | | | | | | | | | | | | | | | | | | | Intel Moorestown platform has a spi-uart device(Maxim3110), which connects to a Designware spi core controller. This patch will add early console function based on it. As it will be used long before Linux spi subsystem get initialised, we simply directly manipulate the spi controller's register to acheive the early console func. This is safe as it will be disabled when devices subsytem get initialised. To use it, user need enable CONFIG_X86_MRST_EARLY_PRINTK in kenrel config and add "earlyprintk=mrst" in kernel command line.

* x86, mrst: add more timer config optionsJacob Pan2010-05-19
| | | | | | | | | | | | | | | | | | | | Always-on local APIC timer (ARAT) has been introduced to Medfield, along with the platform APB timers we have more timer configuration options between Moorestown and Medfield. This patch adds run-time detection of avaiable timer features so that we can treat Medfield as a variant of Moorestown and set up the optimal timer options for each platform. i.e. Medfield: per cpu always-on local APIC timer Moorestown: per cpu APB timer Manual override is possible via cmdline option x86_mrst_timer.

| | | | | | | | | | | | Medfield is the follow-up of Moorestown, it is treated under the same HW sub-architecture. However, we do need to know the CPU type in order for some of the driver to act accordingly. We also have different optimal clock configuration for each CPU type.
