Some IPs have their accessible address space restricted by the

the 4G address boundary (which is 3GiB big), even when the effective
available memory is bigger.

On arm64, board info is not applicable and kernel command line patched into
the DT, so the LMB reservation here makes no sense anymore. On legacy arm32,
this might still be necessary on systems which do not use DT or use legacy
ATAGS. Disable this LMB reservation on arm64.

This also permits Linux DT to specify reserved memory node at address close
to the end of DRAM bank, i.e. overlaping with U-Boot location. Since after
boot, U-Boot will be no more, this is OK.

On implementations that support VHE, the layout of the CPTR_EL2
register depends on whether HCR_EL2.E2H is set.  If the bit is
set, CPTR_EL2 uses the same layout as CPACR_EL1 and can in fact
be accessed through that register.  In that case, jump to the
EL1 code to enable access to the FP/SIMD registers.  This allows
U-Boot to run on systems that pass control to U-Boot in EL2 with
EL2 Host mode enabled such as machines using Apple's M1 SoC.

Extend CONFIG_SYS_BAUDRATE_TABLE and include all standard baudrates and
also nonstandard up to the 6 MBaud. U-Boot's A3720 UART driver can use
baudrates from 300 Baud to 6 MBaud.

This changes all A3720 boards, since all of them include either
mvebu_armada-37xx.h or turris_mox.h config file.

Unfortunately the UART driver in current Linux for Armada 3700 expects
UART's parent clock to be XTAL and calculats baudrate divisor according
to XTAL clock. Therefore we must switch back to XTAL clock before
booting kernel.

Implement .remove method for this driver with DM_FLAG_OS_PREPARE flag
set.

If current baudrate is unsuitable for XTAL clock then we do not change
anything. This can only happen if the user either configured unsupported
settings or knows what they are doing and has kernel patches which allow
usage of non-XTAL parent clock.

Using TBG clock as parent clock for UART allows us using higher
baudrates than 230400.

Turris MOX with external FT232RL USB-UART works fine up to 3 MBaud
(which is maximum for this USB-UART controller), while EspressoBIN with
integrated pl2303 USB-UART also works fine up to 6 MBaud.

Slower baudrates with TBG as a parent clock can be achieved by
increasing TBG dividers and oversampling divider. When using the slowest
TBG clock, minimal working baudrate is 300.

UART parent clock is by default the platform's xtal clock, which is
25 MHz.

The value defined in the driver, though, is 25.8048 MHz. This is a hack
for the suboptimal divisor calculation
  Divisor = UART clock / (16 * baudrate)
which does not use rounding division, resulting in a suboptimal value
for divisor if the correct parent clock rate was used.

Change the code for divisor calculation to round to closest value, i.e.
  Divisor = Round(UART clock / (16 * baudrate))
and change the parent clock rate value to that returned by
get_ref_clk().

This makes A3720 UART stable at standard UART baudrates between 1800 and
230400.
