This change defines resources for OP-TEE service drivers to register
themselves for being bound to when OP-TEE firmware reports the related

driver probe sequence which mandates optee driver is always probe once

a822b9234b Merge branch '2022-09-13-add-support-for-cyclic-function-execution' into next
To quote the author:
This patchset adds the basic infrastructure to periodically execute
code, e.g. all 100ms. Examples for such functions might be LED blinking
etc. The functions that are hooked into this cyclic list should be
small timewise as otherwise the execution of the other code that relies
on a high frequent polling (e.g. UART rx char ready check) might be
delayed too much. This patch also adds the Kconfig option
CONFIG_CYCLIC_MAX_CPU_TIME_US, which configures the max allowed time
for such a cyclic function. If it's execution time exceeds this time,
this cyclic function will get removed from the cyclic list.

How is this cyclic functionality executed?
This patchset integrates the main function responsible for calling all
registered cyclic functions cyclic_run() into the common WATCHDOG_RESET
macro. This guarantees that cyclic_run() is executed very often, which
is necessary for the cyclic functions to get scheduled and executed at
their configured periods.

This cyclic infrastructure will be used by a board specific function on
the NIC23 MIPS Octeon board, which needs to check periodically, if a
PCIe FLR has occurred.

Ideas how to continue:
One idea is to rename WATCHDOG_RESET to something like SCHEDULE and
move the watchdog_reset call into this cyclic infrastructure as well.
Or to perhaps move the shell UART RX ready polling to a cyclic
function.

It's also possible to extend the "cyclic" command, to support the
creation of periodically executed shell commands (for testing etc).

c416f1c0bc bootmenu: add removable media entries
UEFI specification requires booting from removal media using
a architecture-specific default image name such as BOOTAA64.EFI.
This commit adds the removable media entries into bootmenu,
so that user can select the removable media and boot with
default image.

The bootmenu automatically enumerates the possible bootable
media devices supporting EFI_SIMPLE_FILE_SYSTEM_PROTOCOL,
add it as new UEFI boot option(BOOT####) and update BootOrder
variable. This automatically generated UEFI boot option
has the dedicated guid in the optional_data to distinguish it from
the UEFI boot option user adds manually. This optional_data is
removed when the efi bootmgr loads the selected UEFI boot option.

This commit also provides the BOOT#### variable maintenance feature.
Depending on the system hardware setup, some devices
may not exist at a later system boot, so bootmenu checks the
available device in each bootmenu invocation and automatically
removes the BOOT#### variable corrensponding to the non-existent
media device.

1f865ee0ba cyclic: Add 'cyclic list' and 'cyclic demo' commands
This patch adds the cyclic command, which currently only supports the
'list' subcommand, to list all currently registered cyclic functions.
Here an example:

=> cyclic list
function: cyclic_demo, cpu-time: 7010 us, frequency: 99.80 times/s
function: cyclic_demo2, cpu-time: 1 us, frequency: 1.13 times/s

As you can see, the cpu-time is accounted, so that cyclic functions
that take too long might be discovered. Additionally the frequency is
logged.

The 'cyclic demo' commands registers the cyclic_demo() function to
be executed all 'cycletime_ms' milliseconds. The only thing this
function does is delaying by 'delay_us' microseconds.

f7e1de4c6a spi-mem: Add dirmap API from Linux
This adds the dirmap API originally introduced in
Linux commit aa167f3fed0c
("spi: spi-mem: Add a new API to support direct mapping").
This also includes several follow-up patches and fixes.

Changes from Linux include:
* Added Kconfig option
* Changed struct device to struct udevice
* Changed struct spi_mem to struct spi_slave

This patch is obtained from the following patch
https://patchwork.ozlabs.org/project/uboot/patch/20210205043924.149504-3-seanga2@gmail.com/
The corresponding Linux kernel SHA1 is aa167f3fed0c.

d37b4f37ea arm: dts: aspeed: Update SPI flash node settings
For both AST2500 and AST2600, there are three
SPI controllers, FMC(Firmware Memory Controller),
SPI1 and SPI2. The clock source is HCLK. Following
is the basic information for ASPEED SPI controller.

AST2500:
  - FMC:
      CS number: 3
      controller reg: 0x1e620000 - 0x1e62ffff
      decoded address: 0x20000000 - 0x2fffffff

  - SPI1:
      CS number: 2
      controller reg: 0x1e630000 - 0x1e630fff
      decoded address: 0x30000000 - 0x37ffffff

  - SPI2:
      CS number: 2
      controller reg: 0x1e631000 - 0x1e631fff
      decoded address: 0x38000000 - 0x3fffffff

AST2600:
  - FMC:
      CS number: 3
      controller reg: 0x1e620000 - 0x1e62ffff
      decoded address: 0x20000000 - 0x2fffffff

  - SPI1:
      CS number: 2
      controller reg: 0x1e630000 - 0x1e630fff
      decoded address: 0x30000000 - 0x3fffffff

  - SPI2:
      CS number: 3
      controller reg: 0x1e631000 - 0x1e631fff
      decoded address: 0x50000000 - 0x5fffffff

5150e908f5 spi: aspeed: Support AST2400 platform
Although AST2400 is EOL officially, in order to achieve
sustainability and completeness, AST2400 part is added.

For AST2400,
- Five CSs are supported by FMC controller.
- SPI1 controller only supports single CS and there is
  no address segment address register. The CE control
  register of SPI1 is located at the offset 0x04 and
  the 4-byte address mode control bit is bit 13 of
  this register.

4daa6bb6f7 spi: aspeed: Add ASPEED SPI controller driver
Add ASPEED BMC FMC/SPI memory controller driver with
spi-mem interface for AST2500 and AST2600 platform.

There are three SPI memory controllers embedded in an ASPEED SoC.
- FMC: Named as Firmware Memory Controller. After AC on, MCU ROM
       fetches initial device boot image from FMC chip select(CS) 0.

- SPI1: Play the role of a SPI Master controller. Or, there is a
        dedicated path for HOST(X86) to access its BIOS flash mounted
        under BMC. spi-aspeed-smc.c implements the control sequence when
        SPI1 is a SPI master.

- SPI2: It is a pure SPI flash controller. For most scenarios, flashes
        mounted under it are for pure storage purpose.

ASPEED SPI controller supports 1-1-1, 1-1-2 and 1-1-4 SPI flash mode.
Three types of command mode are supported, normal mode, command
read/write mode and user mode.
- Normal mode: Default mode. After power on, normal read command 03h or
               13h is used to fetch boot image from SPI flash.
               - AST2500: Only 03h command can be used after power on
                          or reset.
               - AST2600: If FMC04[6:4] is set, 13h command is used,
                          otherwise, 03h command.
               The address length is decided by FMC04[2:0].

- Command mode: SPI controller can send command and address
                automatically when CPU read/write the related remapped
                or decoded address area. The command used by this mode
                can be configured by FMC10/14/18[23:16]. Also, the
                address length is decided by FMC04[2:0]. This mode will
                be implemented in the following patch series.

- User mode: It is a traditional and pure SPI operation, where
             SPI transmission is controlled by CPU. It is the main
             mode in this patch.

Each SPI controller in ASPEED SoC has its own decoded address mapping.
Within each SPI controller decoded address, driver can assign a specific
address region for each CS of a SPI controller. The decoded address
cannot overlap to each other. With normal mode and command mode, the
decoded address accessed by the CPU determines which CS is active.
When user mode is adopted, the CS decoded address is a FIFO, CPU can
send/receive any SPI transmission by accessing the related decoded
address for the target CS.

This patch only implements user mode initially. Command read/write
mode will be implemented in the following patches.
