On certain places it is required to flush output print buffers to ensure
that text strings were sent to console or serial devices. For example when
printing message that U-Boot is going to boot kernel or when U-Boot is
going to change baudrate of terminal device.
Therefore introduce a new flush() and fflush() functions into console code.
These functions will call .flush callback of associated stdio_dev device.
As this function may increase U-Boot side, allow to compile U-Boot without
this function. For this purpose there is a new config CONSOLE_FLUSH_SUPPORT
which is enabled by default and can be disabled. It is a good idea to have
this option enabled for all boards which have enough space for it.
When option is disabled when U-Boot defines just empty static inline
function fflush() to avoid ifdefs in other code.

Merge branch '2022-09-23-4gb-ddr-in-32bit-ppc' into next
To quote the author, for the first 9 patches:
This patch series fixes U-Boot code to correctly handle RAM size larger
than 2 GB and then fixes fsl ddr driver to do not crash U-Boot when 4 GB
DDR module is detected when U-Boot operates in 32-bit mode (as opposite
of the 36-bit mode).
With this patch series it is possible to boot 32-bit U-Boot with 4 GB
SODIMM DDR3 module without crashes. U-Boot will still use just
CONFIG_MAX_MEM_MAPPED amount of RAM, but it is better than crashing due
to the truncating of 4GB value to 32-bit number (which is zero).
I tested this patch series on powerpc P2020 based board but only with
U-Boot v2022.04 because U-Boot master branch is still broken on P2020.
And then the final two patches here are (in my mind at least) related
clean-ups.
board_f: show_dram_config: Print also real DRAM size
32-bit U-Boot builds cannot use more than around 2 GB of DDR memory. But on
some platforms/boards it is possible to connect also 4 GB SODIMM DDR memory.
U-Boot currently prints only effective size of RAM which can use, which may
be misleading as somebody would expect that this line prints total size of
connected DDR modules. So change show_dram_config code to prints both real
and effective DRAM size if they are different. If they are same then print
just one number like before. It is possible that effective size is just few
bytes smaller than the real size, so print both numbers only in case
function print_size() prints formats them differently.
powerpc/mpc85xx: Fix re-align of unmapped DDR memory message for non-SPL builds
During init_dram() is called also setup_ddr_tlbs_phys() function which may
print message about unmapped DDR memory. So in this case print also
re-aligning filler after unmapped DDR memory message.
Currently U-Boot SPL prints just generic message "2 GiB left unmapped".
Change it to more detailed "2 GiB of DDR memory left unmapped in U-Boot".
This is just U-Boot configuration and operating system may map more (or
also less) memory.
ddr: fsl: Fix re-align of verbose DRAM information for non-SPL builds
During init_dram() is called also compute_lowest_common_dimm_parameters()
function which prints multi-line detailed output. So print also re-aligning
filler after "Detected ?DIMM" line to have "DRAM: " output aligned.
ddr: fsl: Allow to detect 4 GB DDR modules in 32-bit mode
U-Boot core code already handles the case when RAM size is bigger than
CONFIG_MAX_MEM_MAPPED. So there is no need to do duplicate check in fsl ddr
driver for CONFIG_MAX_MEM_MAPPED. Instead simplify code to just check if
RAM size can be representable in phys_size_t type. And avoid printing
warning if phys_size_t is just 1 byte smaller than RAM size, which is the
typical situation with 4 GB DDR module.
ddr: fsl: Fix fsl_ddr_sdram_size() for 4GB modules with 32-bit phys_size_t
Function fsl_ddr_compute() always return size in unsigned long long type,
but function fsl_ddr_sdram_size() returns size in phys_size_t type.
When 36-bit addressing mode is not enabled then phys_size_t type is only
32-bit and thus it cannot store value 4GB (0x100000000). Function
fsl_ddr_sdram_size() in this case returns truncated value 0x0.
Fix this issue by returning the highest representable value, which is
0xffffffff (4GB - 1 byte).
This change fixes crashing of proper U-Boot because it detected 4 GB module
as RAM with zero size.
ddr: fsl: Fix checking for maximal mappable memory
Check needs to be done against CONFIG_MAX_MEM_MAPPED macro and not fixed
size 4GB (as CONFIG_MAX_MEM_MAPPED can be lower and for example for e500
cores it is just 2GB). Also fix printf re-align, which should be applied
only for non-SPL builds, during init_dram() call.

changed type of ram_top member from ulong to phys_addr_t but did not

clk: mediatek: add CLK_BYPASS_XTAL flag to allow bypassing searching clock parent of xtal clock
The mtk clock framework in u-boot uses array index for searching clock
parent (kernel uses strings for search), so we need to specify a special
clock with ID=0 for CLK_XTAL in u-boot.
In the mt7622/mt7629 clock tree, the clocks with ID=0 never call
mtk_topckgen_get_mux_rate, adn return xtal clock directly. This what we
expected.
However for newer chips, they may have some clocks with ID=0 not
representing the xtal clock and still needs mtk_topckgen_get_mux_rate be
called. Current logic will make entire clock driver not working.
This patch adds a flag to indicate that whether a clock driver needs clocks
with ID=0 to call mtk_topckgen_get_mux_rate.

pinctrl: at91-pio4: Add support for pinctrl config subnodes
Previously, in order for the `pinctrl-*` DT node properties
to be properly processed, the pinctrl's subnodes were limited
to only having the `pinmux` property as well as other additional
properties (slew-rate, bias-disable, etc.). Now, with this patch
the pinctrl driver is made to work similarly to the one from Linux.
It can now distinguish between one subnode and a subnode with multiple
subnodes.
pinctrl: at91-pio4: Bind GPIO driver to the pinctrl DT node
This has been done in order to align the DT of U-Boot with the DT
of Linux. In Linux, a phandle from a '-gpio' DT property is linked
to the pinctrl driver, a single driver that handles both pinctrl
settings and offers GPIO API to callers. On the other hand,
U-Boot redirects such phandle to a corresponding UCLASS_GPIO
driver, because U-Boot offers two different types of drivers
in this case: UCLASS_PINCTRL which handles pin functions and
UCLASS_GPIO which handles gpio requests as a gpio provider.
Due to this, we have two drivers in Uboot, but the Devicetree
has a single node. Thus, just one of the drivers can be probed
for the DT node during platform initialization, before relocation.
Our previous solution in U-Boot was to have a different devicetree:
the gpio node has a subnode for the pinctrl driver, which
is not compliant with Linux ABI. Furthermore, our documentation
for this type of nodes mentions no such gpio compatible.
After this patch, we can no longer add nodes with a gpio
compatible in the DT. Thus, in order to link the pinctrl driver to
the gpio one, a hook to the bind method of the former in U-Boot has
been added and the GPIO related compatibles have been removed to
avoid conflict when compatibles are enumerated and bound to drivers
during platform start before relocation. The bind method will attach
the GPIO driver to the pinctrl DT node so that every phandle coming
from '-gpio' DT properties will be redirected to a valid driver
attached to the pinctrl DT node.

This patch makes sure that the Devicetree for the sama7
