vsprintf.c: correct printing of a NULL device path
When printing '%pD' with a value of NULL we want to output
'<NULL>'. But this requires copying to buf. Leave this
to string16.
A unit test is supplied which relies on EFI support in the sandbox.
The development for EFI support in the sandbox is currently in branch
u-boot-dm/efi-working. The branch lacks commit 6ea8b580f06b ("efi_loader:
correct DeviceNodeToText for media types"). Ater rebasing the aforementioned

efi_loader: Call Exit() on return from payload in StartImage()
When a UEFI payload just returns instead of calling the Exit() callback,
we handle that in efi_do_enter() and call Exit on its behalf, so that

We were missing that logic in StartImage(). Call it there too.

efi_loader: Always use EFIAPI instead of asmlinkage
EFI calls are usually defined as asmlinkage. That means we pass all parameters
to functions via the stack x86_32.
On x86_64 however, we need to also stick to the MS ABI calling conventions,
which the EFIAPI define conveniently handles for us. Most EFI functions were
also marked with EFIAPI, except for the entry call.
So this patch adjusts all entry calls to use EFIAPI instead of the manual
asmlinkage attribute.
While at it, we also change the prototype of the entry point to return
efi_status_t instead of ulong, as this is the correct prototype definition.

efi: Conflict efi_loader with different stub bitness
We have 2 users of the EFI headers: efi_loader and the EFI stub. Efi_loader
always expects that the bitness of the definitions it uses is identical to
the execution.
The EFI stub however allows to run x86_64 U-Boot on 32bit EFI and the other
way around, so it allows for different bitness of EFI definitions and U-Boot
environment.
This patch explicitly requests via Kconfig that efi_loader can only be enabled
if the bitness is identical. Because we can run efi_loader on x86_64 without
EFI stub enabled, it also ensures that this case propagates the correct ABI
constraints.

clk: support assigned-clock, assigned-clock-parents, assigned-clock-rates
For various peripherals on Rockchip SoCs (e.g. for the Ethernet GMAC),
the parent-clock needs to be set via the DTS. This adds the required
plumbing and implements the GMAC case for the RK3399.
END
This implements the (newly added) set_parent() operation for the
RK3399 with a focus on allowing the RGMII clock parent to be
configured via the assigned-clock-parents property of the GMAC node.
This implementation supports only the GMAC (in fact only the RGMII
clock parent) and allows to set this clock's parent either to the
internal SCLK_GMAC or to an external clock input (identifiable by it
providing a 'clock-output-name' of "gmac_clkin").

clk: refactor clk_get_by_index() into clk_get_by_indexed_prop()
The logic in clk_get_by_index() may be useful for other properties
than 'clocks': e.g. 'assigned-clocks' and 'assigned-clock-parents'
follows the same model.
This commit refactors clk_get_by_index() by introducing an internal
function clk_get_by_indexed_prop() that allows to specify the name
of the property to process. The original clk_get_by_index() call
is simply directed through this helper function with the property
name fixed to "clocks".

ARM: AM43XX: Call hw_data_init() again after relocation to update *ctrl
hw_data_init() is called before relocation to initialise hardware data.
Since ctrl is initialized to OMAP_SRAM_SCRATCH_SYS_CTRL in
arch/arm/mach-omap2/am33xx/hw_data.c, the pointer *ctrl will not be
updated during relocation and will hold a stale value.
Therefore call hw_data_init() again after relocation to
reinitialize *ctrl.

configs: Replace CONFIG_ISW_ENTRY_ADDR with CONFIG_SYS_TEXT_BASE
Since 7e0ed13 ("Convert ARCH_OMAP2PLUS boards' CONFIG_SYS_TEXT_BASE to
Kconfig"), a default SYS_TEXT_BASE was set for all ARCH_OMAP2PLUS devices.
CONFIG_ISW_ENTRY_ADDR is used to set SYS_TEXT_BASE in qspi boot.
Simplify this by directly assigning SYS_TEXT_BASE in the defconfig.

clk: clk_stm32f: Move SYSCFG clock setup into configure_clocks()
Move SYSCFG clock setup into configure_clocks() instead of calling
clock_setup() from board file.
As this clock is only needed in case of ethernet enabled and as
both stm32f4 and stm32f7 are using the Designware ethernet IP,
we use CONFIG_ETH_DESIGNWARE to only enable this clock if needed.
Move the RMII setup from board_early_init_f() to board_init()
to insure that RMII bit is set only when clock driver is initialized.

atomic-long: Fix warnings on arm64
Several inline functions in this file reference undefined functions in

clk: stm32: retrieve external oscillator frequency from DT
All current STM32F4 supported boards uses a 8MHz external oscillator.
All current STM32F7 supported boards uses a 25MHz external oscillator.
In order to introduce the new stm32f429-evaluation board which uses a
25MHz external oscillator without creating a dedicated struct
stm32_clk_info for this board, retrieve the external oscillator
frequency from DT and set pll_m accordingly to obtain 1MHz for the VCO.

arm: mach-omap2: Pass args to secure ROM in SRAM in SPL
When in early SPL we make some secure ROM calls that can effect
DRAM, due to this it is more stable to store the args for these
calls in SRAM, but uninitialized and zero'd globals are placed
in BSS, located in DRAM. Force our args into the data section
which is in SRAM during SPL.
