Keep track of the re-entries with help of the lr register.
This binary can be re-used and called from various BROM functions.
Only when it's called from the part that handles SPI, NAND or EMMC
hardware it needs to early return to BROM ones.
In download mode when it handles data on USB OTG and UART0
this section must be skipped.
Unlike newer Rockchip SoC models the rk3066 BROM code does not have built-in
support to enter download mode on return to BROM. This binary must check
the boot mode register for the BOOT_BROM_DOWNLOAD flag and reset if it's set.
It then returns to BROM to the end of the function that reads boot blocks.
From there the BROM code goes into a download mode and waits for data
on USB OTG and UART0.

It's happened that glitches on the STM32_RST and STM32_BOOT lines have
put the STM32 companion microcontroller into DFU mode making it not boot
its FW, rendering it useless for the user.
Considering that the STM32 companion microcontroller is always reset on
a reboot or power cycle, resetting it once again in U-Boot SPL isn't
going to hurt it any more.
For ATtiny companion microcontroller, the situation is a bit different
because a reboot or power cycle doesn't reset it. Additionally, since it
can only be reset with a UPDI reset on the STM32_RST line, and that is
virtually impossible to mistakenly trigger, the ATtiny is unlikely to be
in unwanted reset or enter reset because U-Boot toggles STM32_RST line.

RV1126 fails to boot on 2024.01-rc1.
Commit 9e644284ab ("dm: core: Report bootph-pre-ram/sram node as
pre-reloc after relocation") changed the behaviour of bootph-pre-ram, to
limit nodes to spl phase. This caused rv1126 boards to fail to boot with
the current dts.
This patch updates the pmu/grf nodes to bootph-all tags as they are
needed in all phases. This fixes the boot issue on rv1126 boards.

Xilinx is using standard mtd partition layout for quite a long time. It is
used for testing purpose on evaluation boards.
Also #address/size-cells shouldn't be present without nodes which should
use them that's why move them from zynq-7000.dtsi to nand/nor nodes
directly.
The patch was tested on zc706 and zedboard(with also increasing max
frequency and rx bus width).

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 c4df0f6f31 ("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.
Also add test to cover this new function.
