Starting libvirt v5.3.0 with QEMU 4.0.0 use of PCI is automatic
and thus storage is connected via PCI, which is not visible to
U-Boot out-of-the-box.Refactor to do "pci enum" followed by "virtio scan" to see PCI
connected storage, and allow bootloader to load kernel and
initramfs images.Tested with Fedora/RISCV using releases: libvirt 5.4.0 & 5.5.0,
QEMU 4.0.0 and U-Boot 2019.07 RC4.Signed-off-by: David Abdurachmanov

The rproc uclass driver can either be built with SPL_REMOTEPROC
or REMOTEPROC, but the function prototypes in remoteproc.h are
defined only when CONFIG_REMOTEPROC is defined. This can cause
build issues in SPL if CONFIG_REMOTEPROC is not selected.Fix this by replacing the existing precompiler macro usage with
CONFIG_IS_ENABLED.Fixes: ddf56bc7e3ef ("drivers: Introduce a simplified remoteproc framework")

Add support for A/B boot process on AM57xx based boards:
1. Define 'slot_suffix' variable (using 'ab_select' command)
2. Extend 'emmc_android_boot' boot command (add commands for A/B boot
process)'ab_select' command is used to decide which slot should be used for
booting up. A/B metadata resides in 'misc' partition.To activate the A/B boot process, the following config options must be
set:CONFIG_ANDROID_AB=y
CONFIG_CMD_AB_SELECT=yFor successful A/B boot, the corresponding A/B infrastructure must be
involved on Android side [1] (including mounting system as root), and
disk must be partitioned accordingly.When A/B boot is enabled, there are some known limitations currently
exist (not related to A/B patches, need to be implemented later):1. The 'Verified Boot' sequence is not supported
2. dev path to system partition (system_a or system_b) is passed via
'bootargs' as 'root=' argument like 'root=/dev/mmcblk1p12', but
further we'll need to rework it with respect to dm-verity
requirements [2]In case when A/B partitions are not present in system (and A/B boot is
enabled), boot up process will be terminated and next message will be
shown:"boot_a(b) partition not found"

This patch determines the A/B-specific bootloader message structure
that is the basis for implementation of recovery and A/B update
functions. A/B metadata is stored in this structure and used to decide
which slot should we use to boot the device. Also some basic functions
for A/B metadata manipulation are implemented (like slot selection).The patch was extracted from commits [1], [2] with some coding style
fixes.[1] https://android-review.googlesource.com/c/platform/external/u-boot/+/729878/2

The current implementation supports only binary file load.
Add helpers to support ELF32 format (sanity check, and load).
Note that since an ELF32 image is built for the remote processor, the
load function uses the device_to_virt ops to translate the addresses.
Implement a basic translation for sandbox_testproc.Add related tests. Test result:

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 = ;
reg = ;
compatible = "cfi-flash";
};
If secure mode is on, on the other hand, qemu provides dtb with 1 bank:
flash@0 {
bank-width = ;
reg = ;
compatible = "cfi-flash";
};As a result, flash_init()/flash_get_size() will eventually fail.

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'

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")

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.Signed-off-by: Andreas Dannenberg

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 behaviorThis refactoring initially covers MMC/SD card loading (RAW and FS-based).
