This change fix reboot, both configurations
were tested on my Olimex A20 Micro Rev E with debian-12.
This issue was also present and fixed on A20 Lime2 (in 8311e84b18),
quoting Olliver Schinagl:
The lime2 features a too large capacitor on the LDO3 output, which
causes the PMIC to shutdown when enabling power. To be able to still
boot up however, we must gradually enable power on LDO3 for this board.
We do this by enabling both the inrush quirk and the maximum slope the
AXP209 supports.

These SoCs have two SPI controllers that are quite similar to the SPI
on previous Allwinner SoCs. The main difference is that new SoCs
don't have a clock divider (SPI_CCR register) inside SPI IP.
Instead SPI sample mode should be configured depending on the input clock.
For now SPI input clock source selection is not supported by this driver,
and only HOSC@24MHz can be used as input clock. Therefore, according to
the, manual we could change the SPI sample mode from delay half
cycle(default) to normal.
This patch adds a quirk for this kind of SPI controllers

Refactor common QoS code into a new common header file, and the soc

Rename $(soc)_qos_count and $(soc)_qos_data variables to qos_count and
qos_data. When QoS settings of more SoCs are added, only one pair will
be defined at a time, based on the config SOC_K3_$(soc).
This refactoring has been done for 2 major purposes.
- The auto-generated $(soc)_qos_data.c and $(soc)_qos.h files cannot
have any code that is specific to any bootloader. Those files have to
remain agnostic of different bootloader implementations and their
header files.
- The existing implementation was less than ideal and would have enabled
multiple $(soc)_qos_count and $(soc)_qos_data variables for all SoC

The same U-Boot binary is compatible with multiple Verdin AM62 board
variants. However, some of the SoC models can only operate at a maximum
speed of 1 GHz.
Previously, the boards with lower-speed grades were running at
overclocked speeds, leading to kernel complaints about unsupported
configurations.
To resolve this issue, the operating speed has been decreased to the
maximum allowable value across all Verdin AM62 board variants. As a
result, there is a regression in overall boot time, increasing by around
200 milliseconds for the faster SoC variant.
