U-Boot SPL loads the device-tree directly behind main U-Boot overlapping
the .bss section. reserve_fdt() is called in board_init_f() to relocate the
device-tree to a safe location.
Debug UARTs are enabled before board_init_f(). With sbi_dbcn_available in
the .bss section the device-tree is corrupted when _debug_uart_init() is
called in the SBI serial driver. Move the variable to the .data section.

It appears that there is some timing marginality either in the
board layout or the SoC that results in occasional data corruption
on some boards.
We observed this issue on some of the new HiFive Unmatched RevB
boards during volume production as well as some of the original
HiFive Unmatched boards from 2021 in our possession. This means
that there are other boards out there that might have the issue
too.
We have done some limited testing with DDR4 at 1600MT/s and
faulty boards (failing at 1866MT/s) passed.
We plan further testing after we procure a temperature chamber.

When the board was originally added, it enabled some features which
allowed it to bypass Trusted Firmware, but as the feature set of
Linux grew and more features became available, the U-Boot config
options which bypassed TF-A caused issues, so it needs to return

H618 SoC, shipping with up to 4GB of LPDDR4 DRAM, a mini-HDMI connector,
two USB Type-C sockets and a 16MB SPI NOR flash.
There is an FPC connector to connect an expansion board, which sports
two more USB Type-A sockets and a 100MBit Ethernet port. Support for
the expansion board is not in the DT yet, probably a DT overlay would
cover this in the future.

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

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.
