If no CONFIG_OPTEE_LOAD_ADDR is provided i.e. you are not loading OPTEE
into memory in u-boot, then just set the non-existent CONFIG option to
zero, elsewise stringify(CONFIG_OPTEE_LOAD_ADDR) will return
"CONFIG_OPTEE_LOAD_ADDR" - which looks weird in the u-boot environment.

In the Mbed Linux OS bootflow OP-TEE runs before u-boot and provides a DTB
overlay at 0x83100000.
This overlay should subsequently be merged into the main DTB before handing

This patch defines fdtovaddr at 0x83100000.

Reusing the loadaddr to load the boot script breaks some of the logic we
want to have around the bootscript/FIT load addresses. Making a dedicated
bootscript address allows us to differentiate the bootscript load address
from the Linux Kernel or OPTEE load address, thus ensuring that no matter
what the load sequence the bootscript and Kernel/OPTEE binary load
addresses do not conflict.

When obtaining the bootscript from a FIT image we need to specify the name
of the bootscript as defined inside of the FIT.
This patch makes a define that appends a "bootscr" parameter to the source

BD71837 and BD71847 is PMIC intended for powering single-core,
dual-core, and quad-core SoC’s such as NXP-i.MX 8M. BD71847
is used for example on NXP imx8mm EVK.
Add regulator driver for ROHM BD71837 and BD71847 PMICs.
BD71837 contains 8 bucks and 7 LDOS. BD71847 is reduced
version containing 6 bucks and 6 LDOs. Voltages for DVS
bucks (1-4 on BD71837, 1 and 2 on BD71847) can be adjusted
when regulators are enabled. For other bucks and LDOs we may
have over- or undershooting if voltage is adjusted when
regulator is enabled. Thus this is prevented by default.
BD718x7 has a quirk which may leave power output disabled
after reset if enable/disable state was controlled by SW.
Thus the SW control is only allowed for BD71837 bucks
3 and 4 by default. The impact of this limitation must be
evaluated board-by board and restrictions may need to be
modified. (Linux driver get's these limitations from DT and we
may want to implement same on u-Boot driver).

Writing/updating boot image in nand device is not
straight forward in i.MX6 platform and it requires
boot control block(BCB) to be configured.
It becomes difficult to use uboot 'nand' command to
write BCB since it requires platform specific attributes
need to be taken care of.
It is even difficult to use existing msx-nand.c driver by
incorporating BCB attributes like mxs_dma_desc does
because it requires change in mtd and nand command.
So, cmd_nandbcb implemented in arch/arm/mach-imx
BCB contains two data structures, Firmware Configuration Block(FCB)
and Discovered Bad Block Table(DBBT). FCB has nand timings,
DBBT search area, page address of firmware.
On summary, nandbcb update will
- erase the entire partition
- create BCB by creating 2 FCB/DBBT block followed by
1 FW block based on partition size and erasesize.
- fill FCB/DBBT structures
- write FW/SPL on FW1
- write FCB/DBBT in first 2 blocks
for nand boot, up on reset bootrom look for FCB structure in
first block's if FCB found the nand timings are loaded for
further reads. once FCB read done, DTTB will load and finally
firmware will be loaded which is boot image.
Refer section "NAND Boot" from doc/imx/common/imx6.txt for more usage
information.

This patch provides code to implement the CCF clock tree in sandbox. It
uses all the introduced primitives; some generic ones are reused, some
sandbox specific were developed.
In that way (after introducing the real CCF tree in sandbox) the recently
added to clk-uclass.c: clk_get_by_id() and clk_get_parent_rate() are tested
in their natural work environment.
Usage (sandbox_defconfig and sandbox_flattree_defconfig):
./u-boot --fdt arch/sandbox/dts/test.dtb --command "ut dm clk_ccf"

The generic mux clock code for CCF requires reading the clock multiplexer

This patch brings the files from Linux kernel (linux-stable/linux-5.1.y
SHA1: 5752b50477da)to provide clocks support as it is used on the Linux
kernel with Common Clock Framework [CCF] setup.
The directory structure has been preserved. The ported code only supports
reading information from PLL, MUX, Divider, etc and enabling/disabling
the clocks USDHCx/ECSPIx depending on used bus. Moreover, it is agnostic
to the alias numbering as the information about the clock is read from the
device tree.
One needs to pay attention to the comments indicating necessary for U-Boot's
driver model changes.
If needed, the code can be extended to support the "set" part of the clock
management.

This commit adds the clk_get_by_id() function, which is responsible
for getting the udevice with matching clk->id. Such approach allows
re-usage of inherit DM list relationship for the same class (UCLASS_CLK).

to look for UCLASS_CLK related udevices.

If U-Boot is loaded and started from TF-A (you need to change
SYS_TEXT_BASE to 0x60000000), it will hang up at flash initialization.
If secure mode is off (default, or -machine virt,secure=off) at qemu,
it will provide dtb with two flash memory banks:
flash@0 {
bank-width = <0x4>;
reg = <0x0 0x0 0x0 0x4000000 0x0 0x4000000 0x0 0x4000000>;
compatible = "cfi-flash";
};
If secure mode is on, on the other hand, qemu provides dtb with 1 bank:
flash@0 {
bank-width = <0x4>;
reg = <0x0 0x4000000 0x0 0x4000000>;
compatible = "cfi-flash";
};
As a result, flash_init()/flash_get_size() will eventually fail.
With this patch applied, relevant CONFIG values are modified.

The block count entry in the EXT4 filesystem disk structures uses
standard 512-bytes units for most of the typical files. The only
exception are HUGE files, which use the filesystem block size, but those
are not supported by uboot's EXT4 implementation anyway. This patch fixes
the EXT4 code to use proper unit count for inode block count. This fixes
errors reported by fsck.ext4 on disks with non-standard (i.e. 4KiB, in
case of new flash drives) PHYSICAL block size after using 'ext4write'
uboot's command.

The TI AM654x EVM base board and the associated daughtercards have on-
board I2C-based EEPROMs containing board configuration data. Use the
board detection infrastructure introduced earlier to do the following:
1) Parse the AM654x EVM base board EEPROM and populate items like board
name and MAC addresses into the TI common EEPROM data structure
residing in SRAM scratch space
2) Check for presence of daughter card(s) by probing the associated
presence signals via an I2C-based GPIO expander. Then, if such a
card is found, parse the data such as additional Ethernet MAC
addresses from its on-board EEPROM and populate into U-Boot
accordingly
3) Dynamically create an U-Boot ENV variable called overlay_files
containing a list of daugherboard-specific DTB overlays based on
daughercards found.
This patch adds support for the AM654x base board ("AM6-COMPROCEVM")
as well as for the IDK ("AM6-IDKAPPEVM"), OLDI LCD ("OLDI-LCD1EVM")
PCIe/USB3.0 ("SER-PCIEUSBEVM"), 2 Lane PCIe/USB2.0 ("SER-PCIE2LEVM"),

In order to be able to use more advanced driver functionality which often
relies on having BSS initialized during early boot prior to relocation
several things need to be in place:
1) Memory needs to be available for BSS to use. For this, we locate BSS
at the top of the MCU SRAM area, with the stack starting right below
it,
2) We need to move the initialization of BSS prior to entering
board_init_f(). We will do this with a separate commit by turning on
the respective CONFIG option.
In this commit we also clean up the assignment of the initial SP address
as part of the refactoring, taking into account the pre-decrement post-
increment nature in which the SP is used on ARM.

The current U-Boot SPL image loader infrastructure is very powerful,
able to initialize and load from a variety of boot media however it
is strongly geared towards loading specific types of images in a very
specific way. To address the need being able to use this infrastructure
to load arbitrary image files go ahead and refactor it as follows:
- Refactor existing spl_mmc_load_image function into superset function,
accepting additional arguments such as filenames and media load offset
(same concept can also be applied toother spl_XXX_load_image functions)
- Extend the loader function to "remember" their peripheral initialization
status so that the init is only done once during the boot process,
- Extend the FIT image loading function to allow skipping the parsing/
processing of the FIT contents (so that this can be done separately
in a more customized fashion)
- Populate the SPL_LOAD_IMAGE_METHOD() list with a trampoline function,
invoking the newly refactored superset functions in a way to maintain
compatibility with the existing behavior
This refactoring initially covers MMC/SD card loading (RAW and FS-based).
