psci: Do not define do_poweroff() if CONFIG_SYSRESET_CMD_POWEROFF is enabled

2021-07-26T07:18:45+00:00

CONFIG_SYSRESET_CMD_POWEROFF defines do_poweroff() in sysreset-uclass.c
that's why don't define it twice when both CONFIG_SYSRESET_CMD_POWEROFF and
CONFIG_CMD_POWEROFF are enabled. CONFIG_SYSRESET_CMD_POWEROFF depends on
CONFIG_CMD_POWEROFF.

firmware: ti_sci: Add support for Resoure Management at R5 SPL stage.

2021-06-11T13:48:52+00:00

On J721e and J7200, MCU R5 core (boot master) itself would run Device
Manager (DM) Firmware and interact with TI Foundational Security (TIFS)
firmware to enable DMA and such other Resource Management (RM) services.
So, during R5 SPL stage there is no such RM service available and ti_sci
driver will have to directly interact with TIFS using DM to DMSC
channels to request RM resources.

Therefore add DT binding and driver for the same. This driver will
handle Resource Management services at R5 SPL stage.

firmware: ti_sci: Implement GET_RANGE with static data

2021-06-11T13:48:52+00:00

In case of R5 SPL, GET_RANGE API service is not available (as DM
services are not yet up), therefore service such calls locally using
per SoC static data.

firmware: ti_sci: Update ti_sci_msg_req_reboot to include domain

2021-05-27T09:23:14+00:00

The ti_sci_msg_req_reboot message payload has been extended to include a
domain field, but for the purposes of u-boot this should be zero to
reset the entire SoC as it did before. Include domain for completeness
and set to zero to ensure proper operation.

treewide: Convert macro and uses of section(foo) to section("foo")

2021-05-24T18:21:30+00:00

This commit does the same thing as Linux commit 33def8498fdd.

Use a more generic form for __section that requires quotes to avoid
complications with clang and gcc differences.

Remove the quote operator # from compiler_attributes.h __section macro.

Convert all unquoted __section(foo) uses to quoted __section("foo").
Also convert __attribute__((section("foo"))) uses to __section("foo")
even if the __attribute__ has multiple list entry forms.

dm: core: Add address translation in fdt_get_resource

2021-04-29T10:23:39+00:00

Today of_address_to_resource() is called only in
ofnode_read_resource() for livetree support and
fdt_get_resource() is called when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required, but the address translation is done
by ofnode_read_resource() caller, for example in
drivers/firmware/scmi/smt.c::scmi_dt_get_smt_buffer() {
...
	ret = ofnode_read_resource(args.node, 0, &resource);
	if (ret)
		return ret;

	faddr = cpu_to_fdt32(resource.start);
	paddr = ofnode_translate_address(args.node, &faddr);
...

The both behavior should be aligned and the address translation
must be called in fdt_get_resource() and removed for each caller.

psci: add features/reset2 support

2021-04-20T11:31:12+00:00

Adds support for:
* PSCI_FEATURES, which was introduced in PSCI 1.0. This provides API
that allows discovering whether a specific PSCI function is implemented
and its features.
* SYSTEM_RESET2, which was introduced in PSCI 1.1, which extends existing
SYSTEM_RESET. It provides support for vendor-specific resets, providing
reset_type as an additional param.

For additional details visit [1].

Implementations of some functions were borrowed from Linux PSCI driver
code [2].
