bootflow: bootmeth_efi: Set bootp_arch as hex
bootmeth_efi sets up bootp_arch which is read later in bootp.c

bootstd: Avoid freeing a non-allocated buffer
EFI applications can be very large and thus used to cause boot failures
when malloc() space was exhausted.
A recent changed fixed this by using the kernel_addr_r environment var
as the address of the buffer. However, it still frees the buffer when
the bootflow is discarded.
Fix this by introducing a flag to indicate whether the buffer was
allocated, or not.
Note that kernel_addr_r is not the last word here. It might be better
to use lmb to place images. But there is a lot of refactoring to do
before we can remove the environment variables. The distro scripts rely
on them so it is safe for bootstd to do so too.

To quote Andre:
The first few patches are some easy refactorings and fixes, most of them
actually don't change the generated binaries at all. Then there is a
defconfig for a new board, for which we just gained the .dts file from
the last kernel DT sync.
On top there is support for a new PMIC (AXP313), and LPDDR4 support for
the Allwinner H616 SoC, both of which are needed to support new devices
that appeared lately, especially cheap TV boxes.
While those are technically new features, they don't affect existing
boards, for instance the LPDDR4 support code is guarded by a new DRAM
type Kconfig variable. So the risk for regressions is very slim.
Gitlab CI passed, and I booted that briefly on some boards, including an
H616 and an H618 one (with LPDDR4).
The H616 SoC family has support for several types of DRAM: DDR3,
LPDDR3, DDR4 and LPDDR4.
At the moment, the driver only supports DDR3 and LPDDR3 memory.
Let's extend the driver to support the LPDDR4 memory. This type
of memory widely used in device with T507(-H) SoC and new orangepi
zero3 with H618.
The compatibility with T507 is not yet complete, because there
is difference in the phy_init array.

The original H616 DDR3 ODT configuration code wrote board specific values
into a sequence of paired registers.
For LPDDR3 support we needed to special-case one group of registers,
because for that DRAM type we need to write 0 into the lower register of
each pair. That already made the code less readable.
LPDDR4 support will make things even messier, so let's refactor that
code now: We allow to write different values into the lower and upper
half of each pair. The masking is moved into a macro, and use in each
write statement.
The effect is not as obvious yet, as we don't need the full flexibility at
the moment, but the motivation will become clearer with LPDDR4 support.

sunxi: board: simplify early PMIC setup conditions
So far we have a convoluted #ifdef mesh that guards the early AXP PMIC
setup in board.c. That combination of &&, || and negations is very hard
to read, maintain and especially to extend.
Fortunately we have those same conditions already modelled in the
Kconfig file, so they are actually redundant. On top of that the real
reason we have those preprocessor guards in the first place is about the
symbols that are *conditionally* defined: without #ifdefs the build
would break because of them being undefined for many boards.
To simplify this, just change the guards to actually look at the symbols
needed, so CONFIG_AXP_xxx_VOLT instead of CONFIG_AXPyyy_POWER.
This drastically improves the readability of this code, and makes adding
PMIC support a pure Kconfig matter.
Doing this revealed one bug in Kconfig: there is no axp_set_dcdc4() for
the AXP818, even though CONFIG_AXP_DCDC4_VOLT includes that PMIC.
Since the AXP818 wasn't included when calling axp_set_dcdc4() in board.c,
this wasn't an issue, but becomes one now, so also remove the AXP818 from
the DCDC4 Kconfig symbol.

The Standard Host Controller Interface (SDHCI) specification version
3.00 adds support for Advanced DMA (ADMA) for both 64 and 32 bit
widths of DMA. This significantly improves read and write throughput.

arm64: zynqmp: Disable Tri-state for MIO38 Pin
gpio38 is used in SOM's kv260 to reset the Ethernet PHY.
At present, HW reset is not working properly as Tri-state
is enabled for MIO38, causing inappropriate PHY register reads.
Disabled Tri-state for MIO38 to make HW reset work.
arm64: dts: zynqmp: make hw-ecc as the default ecc mode
Except for Linux no other component (i.e., u-boot, fsbl or BootRom) of the
software stack supports software ecc engine. So, make hw-ecc as the default
ecc mode.
This power domain shouldn't be enabled by default. Power domain behavior
should be handled on case by case basis. Adding this property to
zynqmp.dtsi is breaking some suspend/resume cases that's why remove it
from this file.

arm64: zynqmp: Remove fclk driver
fclk will never go upstream that's why removing this node from DT.
All PL (programmable logic) based IPs should handle clocks self without
using this workaround.
spi: cadence_ospi_versal: Add support for 64-bit address
When 64-bit address is passed only lower 32-bit address
is getting updated. Program the upper 32-bit address in the
DMA destination memory address MSBs register.
drivers: firmware: Handle error case in the zynqmp_pm_feature
Unhandled error coming from xilinx_pm_request() but return
value is not read back that's why getting sparse warning
as below:
warning: variable 'ret' set but not used [-Wunused-but-set-variable].
In case of error return the "ret" value.
Provide an explicit configuration option to disable default "lock"
of any flash chip which supports locking. By disabling the lock
config will save some amount of memory and also don't expose the
lock functionality to the users i.e., via sf protect command.
serial: zynqmp: Fetch baudrate from dtb and update
The baudrate configured in .config is taken by default by serial. If
change of baudrate is required then the .config needs to changed and
u-boot recompilation is required or the u-boot environment needs to be
updated.
To avoid this, support is added to fetch the baudrate directly from the
device tree file and update.
The serial, prints the log with the configured baudrate in the dtb.
The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for
$fdtfile env variable") is taken as reference for changing the default
environment variable.
The default environment stores the default baudrate value, When default
baudrate and dtb baudrate are not same glitches are seen on the serial.
So, the environment also needs to be updated with the dtb baudrate to
avoid the glitches on the serial.
