4225f830c5 common: Fix autocompletion with CONFIG_CMDLINE_PS_SUPPORT
The autocompletion did not work if CONFIG_CMDLINE_PS_SUPPORT was enabled
because U-Boot was comparing the prompt string with CONFIG_SYS_PROMPT .
While this works if CONFIG_CMDLINE_PS_SUPPORT is disabled, this no longer
works if it's enabled because user can override the PS1 . Fix this by
checking prompt string against the current PS1 value.

aa2067a869 regulator: Allow enabling GPIO regulator
Drivers need to be able to enable regulators that may be implemented as
GPIO regulators. Example: fsl_esdhc enables the vqmmc supply which is
commonly implemented as a GPIO regulator in order to switch between I/O
voltage levels.

0c1456d571 ARM: correct detection of thumb mode
When a crash occurs in thumb mode the crash dump is incorrect. This is due
to the usage of a non-existing configuration variable CONFIG_ARM_THUMB in
the definition of macro thumb_mode(regs).

Use CONFIG_IS_ENABLED(SYS_THUMB_BUILD) to detect that the code has been
compiled for thumb mode. Remove ARM_THUMB from config_whitelist.txt.

With the patch crash dumps indicate thumb mode correctly.

On a system with thumb mode:

1c9f8f6412 ext4: fix calculating inode blkcount for non-512 blocksize filesystems
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.

03facc7271 board: ti: am654: Use EEPROM-based board detection
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"),
and general purpuse ("AM6-GPAPPEVM") daughtercards.

0c45dfadec armV7R: K3: am654: Allow using SPL BSS pre-relocation
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.

6df8706dc2 arm: K3: Introduce System Firmware loader framework
Introduce a framework that allows loading the System Firmware (SYSFW)
binary as well as the associated configuration data from an image tree
blob named "sysfw.itb" from an FS-based MMC boot media or from an MMC
RAW mode partition or sector.

To simplify the handling of and loading from the different boot media
we tap into the existing U-Boot SPL framework usually used for loading
U-Boot by building on an earlier commit that exposes some of that
functionality.

Note that this initial implementation only supports FS and RAW-based
eMMC/SD card boot.

e1eb6ada4e spl: Make image loader infrastructure more universal
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).

a5a5d997b4 spl: Allow performing BSS init early before board_init_f()
On some platform we have sufficient memory available early on to allow
setting up and using a basic BSS prior to entering board_init_f(). Doing
so can for example be used to carry state over to board_init_r() without
having to resort to extending U-Boot's global data structure.

To support such scenarios add a Kconfig option called CONFIG_SPL_EARLY_BSS
to allow moving the initialization of BSS prior to entering board_init_f(),
if enabled. Note that using this option usually should go along with using
CONFIG_SPL_SEPARATE_BSS and configuring BSS to be located in memory
actually available prior to board_init_f().

70942db4dd mmc: am654_sdhci: Allow driver to probe without PDs specified
We would like to use the driver even without power domains being
specified for cases such as during early boot when the required power
domains have already gotten enabled by the SoC's boot ROM and such
explicit initialization is not needed and possible.
