0ebf9842e5 fastboot: Add default fastboot_set_reboot_flag implementation
Default implementation of fastboot_set_reboot_flag function that depends
on "bcb" commands could be used in general case if there are no need to
make any platform-specific implementation, otherwise it could be
disabled via Kconfig option FASTBOOT_USE_BCB_SET_REBOOT_FLAG.

Please note that FASTBOOT_USE_BCB_SET_REBOOT_FLAG is mutually exclusive
with some platforms which already have their own implementation of this
function.

2b2a771b40 fastboot: Add support for 'reboot fastboot' command
Android 10 adds support for dynamic partitions and in order to support
this userspace fastboot must be used[1]. New tool fastbootd is
included into recovery.

Userspace fastboot works from recovery and is launched if:
1) - Dynamic partitioning is enabled
2) - Boot control block has 'boot-fastboot' value into command field
The bootloader is expected to load and boot into the recovery image
upon seeing boot-fastboot in the BCB command. Recovery then parses the
BCB message and switches to fastbootd mode[2].

Please note that boot script is expected to handle 'boot-fastboot'
command in BCB and load into recovery mode.

Bootloader must support 'reboot fastboot' command which should reboot
device into userspace fastboot to accomodate those changes[3].

Another command that bootloader must support[3] is 'reboot recovery'. This
command should simply reboot device into recovery mode.

73f4ebb659 dfu: fix dfu tftp on sandbox
The environment variable loadaddr is in the virtual address space of the
sandbox. To get the actual memory address where the FIT image has been
loaded we have to convert this address according to the memory mapping of
the sandbox.

Equally the addresses in the *.its file have to be converted when used in
the dfu_ram driver.

SCxSR_RDxF flag is cleared in sh_serial_getc_generic(), while the
FIFO still contains data. If that happens, the serial_getc_check()

cf9f38064d x86: mtrr: Fix parsing of "mtrr list" command
The command 'mtrr' does not recognize the 'list' subcommand any more
since the code restructuring in commit b2a76b3fe7 ("x86: mtrr:
Restructure so command execution is in one place").

The if-else parsing the command arguments does not take 'list' into
account: the if-branch is intended for no subcommands, the else-branch
is intended for the non-list subcommands (which all expect additional
arguments). Calling the 'mtrr list' subcommand leads to a "return
CMD_RET_USAGE" in the else-branch.

Fix this by changing the else-branch to explicitly checking for
if (cmd != 'l').

a65e65939e arm: mvebu: Espressobin: Setup MTD partitions when booting kernel
Due to different partition layouts in different U-Boot versions, DTS for
Espressobin in Linux does not contain any definition of MTD partitions.
See commit https://git.kernel.org/stable/c/00954566464a4 for more details.

This patch via ft_board_setup() hook fills current partition layout used by
U-Boot, so booted kernel would see correct MTD partitions layout.

U-Boot env partition is calculated from CONFIG_ENV_OFFSET option.

First partition contains secure firmware, ARM trusted firmware and U-Boot
with checksums. So it is not possible to replace just one image (e.g.
U-Boot) without updating other parts where is stored checksum of U-Boot.
Therefore there is no extra partition defined for U-Boot and first
partition is called just 'firmware'.

828d326216 arm64: a37xx: pci: Assert PERST# signal when unloading driver
This change ensures that PCIe card is put into reset state when U-Boot
stops using it.

DM_FLAG_OS_PREPARE ensures that U-Boot executes driver's remove callback
prior booting Linux kernel.

Linux kernel pci-aardvark driver needs to reset PCIe card via PERST# signal
prior initializing it. If it does not issue reset then some PCIe cards
(specially Compex WiFi cards) are not detected at all.

Putting PCIe card into reset state prior booting Linux kernel would ensure
that card would be properly reset at time when Linux kernel starts
initializing pci-aardvark driver.

563b85bd88 arm64: a37xx: pci: Make PCIe Reset GPIO DT compatible with Linux kernel DT
Change active-high to active-low and change DT property name from
reset-gpio to reset-gpios. This format of gpio reset is used by
pci-aardvark driver in Linux kernel.
