x86: acpi: Not every platform has serial console a first device

2019-03-10T00:17:00Z

We may not do an assumption that current console device is always a first of UCLASS_SERIAL one. For example, on properly described Intel Edison board the console UART is a third one. Use current serial device as described in global data.

x86: acpi: Don't touch ACPI hardware in write_acpi_tables()

2018-07-20T01:33:22Z

write_acpi_tables() currently touches ACPI hardware to switch to ACPI mode at the end. Move such operation out of this function, so that it only does what the function name tells us. Signed-off-by: Bin Meng Reviewed-by: Simon Glass Tested-by: Andy Shevchenko

x86: acpi: Move APIs unrelated to ACPI tables generation to a separate library

2018-07-20T01:33:22Z

acpi_find_fadt(), acpi_find_wakeup_vector() and enter_acpi_mode() are something unrelated to ACPI tables generation. Move these to a separate library. This also fixes several style issues reported by checkpatch in the original codes. Signed-off-by: Bin Meng Reviewed-by: Simon Glass Tested-by: Andy Shevchenko

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini

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.
