* mailbox: apple: Add driver for Apple IOP mailboxMark Kettenis2022-02-103-0/+104
| | | | | | | | | | | | | | | | | This mailbox driver provides a communication channel with the Apple IOP controllers found on Apple SoCs. These IOP controllers are used to implement various functions such as the System Manegement Controller (SMC) and NVMe storage. It allows sending and receiving a 96-bit message over a single channel. The header file with the struct used for mailbox messages is taken straight from Linux.

* mailbox: k3-sec-proxy: Extend valid thread IDsDave Gerlach2021-05-121-9/+1
| | | | | | | | | | | | AM64x uses a different thread mapping that existing K3 SoCs, so update the valid thread ID list to include those used for AM64x. Also remove the comment identifying the purpose of each thread ID. The purpose of the thread ID is specified when describing the threads in the device tree and the same ID can mean different things on different SoCs, so the comment is not useful.

* common: Drop asm/global_data.h from common headerWIP/2021-02-02-drop-asm_global_data-when-unusedSimon Glass2021-02-021-0/+1
| | | | | | | | | | | | Move this out of the common header and include it only where needed. In a number of cases this requires adding "struct udevice;" to avoid adding another large header or in other cases replacing / adding missing header files that had been pulled in, very indirectly. Finally, we have a few cases where we did not need to include <asm/global_data.h> at all, so remove that include.

* dm: treewide: Rename auto_alloc_size members to be shorterSimon Glass2020-12-136-6/+6
| | | | | | | | | | | | This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass <sjg@chromium.org>

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-074-8/+4
| | | | | | | | | | | | | | | | | | | | 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 <trini@konsulko.com>

* dm: Rename dev_addr..() functionsSimon Glass2017-06-011-1/+1
| | | | | | | | | | | | | | | | | | | These support the flat device tree. We want to use the dev_read_..() prefix for functions that support both flat tree and live tree. So rename the existing functions to avoid confusion. In the end we will have: 1. dev_read_addr...() - works on devices, supports flat/live tree 2. devfdt_get_addr...() - current functions, flat tree only 3. of_get_address() etc. - new functions, live tree only All drivers will be written to use 1. That function will in turn call either 2 or 3 depending on whether the flat or live tree is in use. Note this involves changing some dead code - the imx_lpi2c.c file.

A mailbox is a hardware mechanism for transferring small message and/or notifications between the CPU on which U-Boot runs and some other device such as an auxilliary CPU running firmware or a hardware module. This patch defines a standard API that connects mailbox clients to mailbox providers (drivers). Initially, DT is the only supported method for connecting the two. The DT binding specification (mailbox.txt) was taken from Linux kernel v4.5's Documentation/devicetree/bindings/mailbox/mailbox.txt.
