should select DM_MMC. No drivers need to depend on DM_MMC being enabled
now, so remove that from dependency lists. This now means that a number

I had previously set CONFIG_64BIT for arm64. This patchset does the

if it's a 32 or 64 bit system for the CHECKER.

There is necessary to do some steps to compose boot images. These steps
were in scripts in layers for a while. That's why introduce description via
binman to simplify wiring and remove all scripting around.
This should make sure that everybody is up2date with the latest versions.
The first step is to create fit image with DTBs with descriptions in
configuration node which is written as regular expression to match all SOM
versions.
Description is there for k24 and k26 in spite of low level psu_init
configuration is different. The reason is that it goes to u-boot.itb image
which is the same for k24 and k26.
u-boot.itb is another image which is generated. It is normally generated
via arch/arm/mach-zynqmp/mkimage_fit_atf.sh but this script is supposed to
be deprecated.
FIT image by purpose is using 64bit addresses to have default option to
move images to high DDR (above 4GB). TF-A and TEE are optional components
but in the most cases TF-A is present all the time and TEE(OP-TEE) is used
by some configurations too.
3rd generated image is boot.bin with updated user field which contains
version number. This image can be used with updated Image Selector
which supports A/B update mechanisms with rollback protection.
4th image is image.bin which binary file which contains boot.bin and
u-boot.itb together and can be programmed via origin Image Selector.
This image can be also used for creating one capsule which contains both
boot images (in SPL boot flow).

When ACPI is enabled over FDT the APs cannot be brought out of reset
by the OS using the "FDT spin-table" mechanism, as no FDT is provided
to the OS. The APs must be released out of reset in u-boot and then
brought up in an ACPI compliant fashion.
When ARMV8_MULTIENTRY is specified, the APs are released from reset
and will enter U-Boot after it has been relocated as well.
By default ARMV8_MULTIENTRY is not selected, keeping existing behaviour.

Unlike other Arm based platforms the machine only provides a minimal

Due to this design a full DTB is added here as well that allows U-Boot's

Greg Malysa <greg.malysa@timesys.com> says:
This series adds support for the ADI SC5xx machine type and includes two
core drivers that are required for being able to boot any board--a UART
driver, the gptimer driver which is used as a clock reference (CNTVCNT
is not supported on the armv7 sc5xx SoCs) and the clock tree driver. Our
corresponding Linux support relies on u-boot configuring the clocks
correctly before booting, so it is not possible to boot any board
without the CGU/CDU configuration happening here. There are also no
board files, device trees, or defconfigs included here, but some common
definitions that will be used to build board files currently are. The
sc5xx SoCs themselves include many armv7 families (sc57x, sc58x, and
sc594) all using an ARM Cortex-A5, and one armv8 family (sc598) indended
to be a drop-in replacement for the SC594 in terms of peripherals, with
a Cortex-A55 instead.
Some of the configuration code in dmcinit and clkinit is quite scary and
causes a lot of checkpatch violations. It is modified from code
initially provided by ADI, but it has not been fully rewritten. There's
a question of how important it is to clean up this code--it has some
quality violations, but it has been in use (including in production) for
over two years and is known to work for performing the low level SoC
initialization, while a rewrite might introduce timing or sequence bugs
that could take a significant amount of time to detect in the future.
Add support for the SC5xx machine type from Analog Devices. This
includes support for the SC57x, SC58x, SC59x, and SC59x-64 SoCs, which
have many common features such as common ADI IP blocks, and SHARC DSP
cores. This commit introduces core functionality required for all boards
using an SC5xx SoC, such as:
- SPL configuration
- Required CPU hooks such as reset
- Boot ROM interaction to load the stage 2 bootloader in the reference
configuration. Other options are possible but not officially supported
at this time
- SoC-common configuration expected to be reused by all boards
- Early initialization for system clocks and DDR controller

Historically, Qualcomm boards have relied on heavy hardcoding in U-Boot,
in many cases to the specific SoC but also to the board itself (e.g.
memory map). This has been largely resolved by modernising the Qualcomm
drivers in U-Boot, however the board code still largely follows this
model.
This patch removes the board specific memory maps and duplicated board
init code, replacing it with generic init code.
The memory map is now built at runtime based on data read from DT, this
allows for the memory map to be provided without having to recompile
U-Boot. Support is also added for booting with appended DTBs, so that
the first-stage bootloader can populate the memory map for us.
The sdm845 specific init code is dropped entirely, it set an environment
variable depending on if a button was pressed, but this variable wasn't
used in U-Boot, and could be written to use the button command instead.
The KASLR detection is also dropped as with appended dtb, the kaslr seed
can be read directly from the DTB passed to U-Boot.
A new qcom_defconfig is added, with the aim of providing a generic
U-Boot configuration that will work on as many Qualcomm boards as
possible. It replaces the defconfig files for the Dragonboard 845c,
Galaxy S9, and QCS404 EVB. For now the db410c and 820c are excluded as
they still have some board code left.
Similarly, the config headers for db845c, starqltechn, and qcs404-evb
are replaced by a single qcom header.
The previously db410c-specific board_usb_init() function is made to be
generic and is added to mach-snapdragon. While we lack proper modelling
for USB configuration, using a well-known named pinctrl state is a
reasonably generic middleground, and works using upstream DT. This
function will do nothing unless the USB node has a pinctrl state named
"device", in which case it will be set when entering USB peripheral
mode.
