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].

scmi: translate the resource only when livetree is not activated

2021-04-12T21:45:40+00:00

Call the translation function on the ofnode_read_resource result only
when the livetree is not activated.

Today of_address_to_resource() calls ofnode_read_resource() for livetree
support and fdt_get_resource() when livetree is not supported.

The fdt_get_resource() doesn't do the address translation
so when it is required when livetree is activated but this address
translation is already done by ofnode_read_resource().

scmi: correctly configure MMU for SCMI buffer

2021-04-12T21:44:55+00:00

Align the MMU area for SCMI shared buffer on section size;
use the ALIGN macro in mmu_set_region_dcache_behaviour call.

Since commit d877f8fd0f09 ("arm: provide a function for boards init
code to modify MMU virtual-physical map") the parameter of
mmu_set_region_dcache_behaviour need to be MMU_SECTION_SIZE
aligned.

Fix inline comments and empty line in scmi driver and test files.
