Add useful default debug uart values for all Versal platforms to simplify
and speed up debug uart enabling.
The similar change has been done for Zynq/ZynqMP by commit ad55d99e3cc3
("serial: Setup serial base and freq for zynq/zynqmp").

Tom Rini <trini@konsulko.com> says: This series switches to always using $(PHASE_) in Makefiles when building rather than $(PHASE_) or $(XPL_). It also starts on documenting this part of the build, but as a follow-up we need to rename doc/develop/spl.rst and expand on explaining things a bit.

It is confusing to have both "$(PHASE_)" and "$(XPL_)" be used in our Makefiles as part of the macros to determine when to do something in our Makefiles based on what phase of the build we are in. For consistency, bring this down to a single macro and use "$(PHASE_)" only. Signed-off-by: Tom Rini <trini@konsulko.com>
Simon Glass <sjg@chromium.org> says: The membuff implementation curently has no tests. It also assumes that head and tail can never correspond unless the buffer is empty. This series provides a compile-time flag to support a 'full' flag. It also adds some tests of the main routines. The data structure is also renamed to membuf which fits better with U-Boot. There may be some cases in the code which could be optimised a little, but the implementation is functional. Link: https://lore.kernel.org/r/20250318152059.1464369-1-sjg@chromium.org
The double 'f' is not necessary and is a bit annoying as elsewhere in U-Boot we use 'buf'. Rename all the functions before it is used more widely. Signed-off-by: Simon Glass <sjg@chromium.org>
Depending on the platform, there may be multiple clock sources required to enable a UART. Use the bulk functions to get and enable the clocks when the UART probes. This can facilitate the removal of functions to manually enable the clock. This is made dependent on CLK_CCF which is used on imx6q, imx8m[mnqp], several imxrt, imx9. If/when the UART clock registration is done for older boards, this limitation could be updated. Signed-off-by: Adam Ford <aford173@gmail.com> Reviewed-by: Peng Fan <peng.fan@nxp.com>
On PowerPC platforms with TPL enabled and SPL_SYS_NS16550_SERIAL enabled, today this builds under TPL as well due to how $(XPL_) is defined. Add the TPL_SYS_NS16550_SERIAL itself for consistency and clarity. Signed-off-by: Tom Rini <trini@konsulko.com>
CI: https://source.denx.de/u-boot/custodians/u-boot-stm/-/pipelines/25112 - Add drivers for MFD STM32 TIMERS and STM32 PWM and enable them on stm32mp135f-dk - Restrict _debug_uart_init() usage in STM32 serial driver - Add support for environment in eMMC on STM32MP13xx DHCOR SoM - Introduce DH STM32MP15xx DHSOM board specific defconfigs - Fix CONFIG_BOOTCOUNT_ALTBOOTCMD update on DH STM32MP1 DHSOM - Update maintainer for board stm32f746-disco - Fix Linux cmdline for stm32f769-disco - Cleanup in stm32f***-u-boot.dtsi and in board_late_init() by removing legacy led and button management.
Since commit 948da7773e34 ("arm: Add new config option ARCH_VERY_EARLY_INIT")
debug_uart_init() is called respectively in crt0.S and crt0_64.S.
That means that _debug_uart_init() is called for all STM32MP platforms
even for those which doesn't support SPL_BUILD.
So restrict _debug_uart_init() execution for platforms which can have
SPL_BUILD enabled (STM32MP1 platform only).
It's more needed to call debug_uart_init() in stm32mp1/cpu.c.
