When copying the name of a stdio device we must ensure that it is NUL
terminated before passing it to strcmp() to avoid a buffer overrun.
Truncating the name field leads to failure to deregister a stdio device.
When copying we must ensure that the name field sizes match.

Use uintptr_t instead of phys_addr_t where appropriate, so passing the
addresses to writel() doesn't result in compile warnings when PHYS_64BIT
is set for 32bit builds (which is actually a useful configuration, as
the K3 SoC family boots from an R5 SPL, which may pass bank information
based on gd->bd->bi_dram to fdt_fixup_memory_banks() etc., so PHYS_64BIT
is needed for fixing up the upper bank).

In case of new memory range to be added is coalesced

And there is possibility that, then region in which new memory
range added is not adjacent to next region. But have some
sections are overlapping.
So along with adjacency check with next lmb region,
check for overlap should be done.
In case overlap is found, adjust and merge these two lmb

Allow for a proper configuration of CFI flash banks avaialble on the vexpress_ca9x4
board. Without this option, the CFI flash incorrectly detects that the board has two
banks of 32MB flash devices, while in reality, the board provides
two flash banks, each with 64MB size. As a result, it becomes impossible to e.g. to
save u-boot env in flash. According to device tree for this board and
its implementation in QEMU, the CFI width should be set to 32 bits.
After applying this fix, CFI flash will correctly detect both flash
banks each with a size of 64MB. As as result the functionality of e.g. saving u-boot
env will work correctly.
Tested on QEMU 6.2.0.

If the source .env file changes to one that is also older than the
generated env.txt file then the .env file is not regenerated. This
means when switching board configs we do not regenerate the env.
This can be tested with:
$ make j721e_evm_a72_defconfig
$ make # this may fail to complete but that is okay for this test
$ make am64x_evm_a53_defconfig
$ make
$ vim include/generated/env.txt
Note this is still the J721e env not the AM64 config as expected.
As ENV_FILE is set based on configuration, regenerate anytime

The board is sharing a lot of components with zcu208 but it contains
differet silicon and also several components are done differently.
The board has 4GB memory connected to PS and additional 4GB connected to
PL. Compare to zcu208 sata support has been dropped and only USB3.0 is
using GTR (lane2). Others GTRs are routed to connectors.
MIO configuration is also shared with zcu111.
The board is using si5381 chip compare to si5341 which is normally used.
And as of now there is no Linux driver for this chip. PS reference clock is
generated out of si570 chip which is also new approach compare to zcu208.

VPXA2785(vp-x-a2785-00) is evaluation board which contains two PCIe-Edge
fingers, one for PCIe-B(gen5x8) and one for CPM(dual gen5x8, gen5x16).
Each of the ports can operate in endpoint or root port mode. This allows
the single card to be used for both root port, endpoint, and switch modes.
The board is designed in the similar manner as others Versal boards. It
means board also have ZynqMP Zu4 System Controller which is described in a

System controllers are pretty much the same on the all boards that's why
use autodetection based on i2c eeprom. This should end up with having only
one BSP for all SCs with only DT overlays to cover different i2c
structures.
All MIOs are fixed by the spec that's why not a problem to description
pinctrl setting.
Apart from eth phy reset, it also set proper phy delays.
The TI DP83867 PHY datasheet says:
T1: Post RESET stabilization time == 195us
T3: Hardware configuration pins transition to output drivers == 64us
T4: RESET pulse width == 1us
So with a little overhead set 'reset-assert-us' to 100us (T4) and
'reset-deassert-us' to 280us (T1+T3).
NOTE: The tuning of TI DP83867 phy reset delay is derived from linux
upstream commit: 5dbadc848259(arm64: dts: fsl: add support for Kontron
pitx-imx8m board).
i2c structure on Xilinx Versal evaluation platforms contain a lot of
devices but also connection to connectors like SFP. Because of this
complicated structure with also all level shifters, i2c muxes, etc. not all
devices are able to reliably work on 400kHz even if they are compatible
with this speed. That's why set i2c frequency to 100KHz to increase
reliability of the i2c bus.
