17fa032671 serial, ns16550: bugfix: ns16550 fifo not enabled
commit: 65f83802b7 "serial: 16550: Add getfcr accessor"
breaks u-boot commandline working with long commands
sending to the board.

Since the above patch, you have to setup the fcr register.

For board/archs which enable OF_PLATDATA, the new field
fcr in struct ns16550_platdata is not filled with a
default value ...

This leads in not setting up the uarts fifo, which ends
in problems, when you send long commands to u-boots
commandline.

Detected this issue with automated tbot tests on am335x
based shc board.

The error does not popup, if you type commands. You need
to copy&paste a long command to u-boots commandshell
(or send a long command with tbot)

Possible boards/plattforms with problems:
./arch/arm/cpu/arm926ejs/lpc32xx/devices.c
./arch/arm/mach-tegra/board.c
./board/overo/overo.c
./board/quipos/cairo/cairo.c

5e4a6db8f4 armv8: ls1012a: define esdhc_status_fixup for RDB board
On LS1012ARDB board, three dual 1:4 mux/demux devices drive the SDHC2
signals to eMMC, SDIO wifi, SPI and Ardiuno shield. Only when we select
eMMC and SDIO wifi, the SDHC2 could be used. Otherwise, the command
inhibit bits of eSDHC2_PRSSTAT register will never release. This would
cause below continious error messages in linux since it uses polling
mode to detect card.
"mmc1: Controller never released inhibit bit(s)."
"mmc1: Controller never released inhibit bit(s)."
"mmc1: Controller never released inhibit bit(s)."
This patch is to define esdhc_status_fixup function for RDB to disable
SDHC2 status if no SDIO wifi or eMMC is selected.

For now we keep the boot0 header in the U-Boot proper, as this allows
to still use boot0 as an SPL replacement without hurting the SPL use
case.
We disable FEL support for now by making its compilation conditional
and disabling it for ARM64, as the code isn't ready yet.

52e3182b82 sunxi: provide default DRAM config for sun50i in Kconfig
To avoid enumerating the very same DRAM values in defconfig files
for each and every Allwinner A64 board out there, let's put some sane
default values in the Kconfig file.
Boards with different needs can override them at any time.

83843c9b3a sunxi: A64: do an RMR switch if started in AArch32 mode
The Allwinner A64 SoC starts execution in AArch32 mode, and both
the boot ROM and Allwinner's boot0 keep running in this mode.
So U-Boot gets entered in 32-bit, although we want it to run in AArch64.

By using a "magic" instruction, which happens to be an almost-NOP in
AArch64 and a branch in AArch32, we differentiate between being
entered in 64-bit or 32-bit mode.
If in 64-bit mode, we proceed with the branch to reset, but in 32-bit
mode we trigger an RMR write to bring the core into AArch64/EL3 and
re-enter U-Boot at CONFIG_SYS_TEXT_BASE.
This allows a 64-bit U-Boot to be both entered in 32 and 64-bit mode,
so we can use the same start code for the SPL and the U-Boot proper.

We use the existing custom header (boot0.h) functionality, but restrict
the existing boot0 header reservation to the non-SPL build now. A SPL
wouldn't need such header anyway. This allows to have both options
defined and lets us use one for the SPL and the other for U-Boot proper.

Also add arch/arm/mach-sunxi/rmr_switch.S, which contains the original
ARM assembly code and instructions how to re-generate the encoded
version.

b5402d13d4 sunxi: introduce extra config option for boot0 header
The ENABLE_ARM_SOC_BOOT0_HOOK option is a generic option shared with
other boards. To allow alternative code to be inserted, we create
another, now function specific config symbol on top of it to simplify
later additions. No functional change at this time.
