x86: acpi: Use an API to get the ACPI RSDP table address

2018-01-30T14:34:37Z

At present the acpi_rsdp_addr variable is directly referenced in setup_zimage(). This changes to use an API for better encapsulation and extension. Signed-off-by: Bin Meng Reviewed-by: Andy Shevchenko

x86: zImage: Propagate acpi_rsdp_addr to kernel via boot parameters

2018-01-30T06:29:07Z

New field acpi_rsdp_addr, which has been introduced in boot protocol v2.14 [1], in boot parameters tells kernel the exact address of RDSP ACPI table. Knowing it increases robustness of the kernel by avoiding in some cases traversal through a part of physical memory. It will slightly reduce boot time by the same reason. [1] See Linux kernel commit 2f74cbf ("x86/boot: Add the ACPI RSDP address to struct setup_header::acpi_rdsp_addr") @ https://git.kernel.org/pub/scm/linux/kernel/git/tip/tip.git/commit/?id=2f74cbf for the details.

x86: tangier: Add Bluetooth to ACPI table

2018-01-08T08:52:25Z

As defined on reference board followed by Intel Edison a Bluetooth device is attached to HSU0, i.e. PCI 0000:04.1. Describe it in ACPI accordingly. Note, we use BCM2E95 ID here as one most suitable for such device based on the description in commit message of commit 89ab37b489d1 ("Bluetooth: hci_bcm: Add support for BCM2E95 and BCM2E96") in the Linux kernel source tree.

x86: tangier: Use actual GPIO hardware numbers

2018-01-08T08:52:25Z

The recent commit 03c4749dd6c7 ("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux GPIO translation") in the Linux kernel reveals the issue we have in ACPI tables here, i.e. we must use hardware numbers for GPIO resources and, taking into consideration that GPIO and pin control are *different* IPs on Intel Tangier, we need to supply numbers properly. Besides that, it improves user experience since the official documentation for Intel Edison board is referring to GPIO hardware numbering scheme.

x86: tangier: Use official ACPI HID for FLIS IP

x86: baytrail: fsp: Use a function to update the Azalia config pointer

At present we directly pass the Azalia config pointer to the FSP UPD. This updates to use a function to do the stuff, like Braswell does. Signed-off-by: Bin Meng Reviewed-by: Stefan Roese

x86: fsp: Consolidate Azalia header file

2017-10-19T03:37:51Z

So far there are two copies of Azalia struct defines with one in baytrail and the other one in braswell. This consolidates these two into one, put it in the common place, and remove the prefix pch_ to these structs to make their names more generic. This also corrects reset_wait_timer from us to ms.

Intel Tangier SoC is a part of Intel Merrifield platform which doesn't utilize ACPI by default. Here is an attempt to unleash ACPI flexibility power on Intel Merrifield based platforms. The change brings minimum support of the devices that found on Intel Merrifield based end user device. Signed-off-by: Andy Shevchenko Reviewed-by: Bin Meng
