2015-12-22acpi: aml: add helper for Opcode Arg2 Arg2 [Dst] AML patternIgor Mammedov
Currently AML API doesn't compose terms in form of following pattern: Opcode Arg2 Arg2 [Dst] but ASL used in piix4/q35 DSDT ACPI tables uses that form, so for clean conversion of it, AML API should be able to handle an optional 'Dst' argumet used there. Since above pattern is used by arithmetic/bit ops, introduce helper that they could reuse. It reduces code duplication in existing 5 aml_foo() functions and also will prevent more duplication when exiting functions are extended to support optional 'Dst' argument.

NFIT is defined in ACPI 6.0: 5.2.25 NVDIMM Firmware Interface Table (NFIT) Currently, we only support PMEM mode. Each device has 3 structures: - SPA structure, defines the PMEM region info - MEM DEV structure, it has the @handle which is used to associate specified ACPI NVDIMM device we will introduce in later patch. Also we can happily ignored the memory device's interleave, the real nvdimm hardware access is hidden behind host - DCR structure, it defines vendor ID used to associate specified vendor nvdimm driver. Since we only implement PMEM mode this time, Command window and Data window are not needed The NVDIMM functionality is controlled by the parameter, 'nvdimm', which is introduced for the machine, there is a example to enable it: -machine pc,nvdimm -m 8G,maxmem=100G,slots=100 -object \ memory-backend-file,id=mem1,share,mem-path=/tmp/nvdimm1,size=10G -device \ nvdimm,memdev=mem1,id=nv1 It is disabled on default Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Signed-off-by: Xiao Guangrong <guangrong.xiao@linux.intel.com> Reviewed-by: Michael S.

This deletes a block of code that raised a command index error if a command returned response data, but the guest did not set the appropriate bits in the response register to handle such a response. I cannot find any documentation that suggests the controller should behave in this way, the error code doesn't make sense (command index error is defined for the case where the index in a response does not match that of the issued command), and in at least one case (CMD23 issued by UEFI on Raspberry Pi 2), actual hardware does not do this.

2015-12-22sd: sdhci: Delete over-zealous power checkPeter Crosthwaite
This check was conditionalising SD card operation on the card being powered by the SDHCI host controller. It is however possible (particularly in embedded systems) for the power control of the SD card to be managed outside of SDHCI. This can be as trivial as hard-wiring the SD slot VCC to a constant power-rail. This means the guest SDHCI can validly opt-out of the SDHCI power control feature while still using the card. So delete this check to allow operation of the card with SDHCI power control. This is needed for at least Xilinx Zynq and Raspberry Pi, and also makes Freescale i.MX25 work for me. The digilent Zybo board has a public schematic which shows SD VCC hardwiring: http://digilentinc.com/Data/Products/ZYBO/ZYBO_sch_VB.3.pdf bottom of page 3.
