serial: zynqmp: Fetch baudrate from dtb and update

2023-11-07T12:47:08Z

The baudrate configured in .config is taken by default by serial. If change of baudrate is required then the .config needs to changed and u-boot recompilation is required or the u-boot environment needs to be updated. To avoid this, support is added to fetch the baudrate directly from the device tree file and update. The serial, prints the log with the configured baudrate in the dtb. The commit c4df0f6f315c ("arm: mvebu: Espressobin: Set default value for $fdtfile env variable") is taken as reference for changing the default environment variable. The default environment stores the default baudrate value, When default baudrate and dtb baudrate are not same glitches are seen on the serial. So, the environment also needs to be updated with the dtb baudrate to avoid the glitches on the serial. Also add test to cover this new function.

configs: Add support in Kconfig and convert for armada boards

2023-11-07T12:47:08Z

Move the DEFAULT_ENV_IS_RW to Kconfig for easier configuration. Hence, add the CONFIG_DEFAULT_ENV_IS_RW config to the defconfig files to allow enabling them for armada boards.

serial: Drop mention of SPL/TPL_SYS_MALLOC_F

2023-10-06T18:38:12Z

These symbols do not (yet) exist, so drop the usage of them in the serial Kconfig file. It has no effect. Signed-off-by: Simon Glass

spl: Use CONFIG_SPL... instead of CONFIG_..._SPL_...

2023-10-06T18:38:11Z

We like to put the SPL first so it is clear that it relates to SPL. Rename various malloc-related options which have crept in, to stick to this convention. Signed-off-by: Simon Glass Reviewed-by: Marcel Ziswiler Reviewed-by: Martyn Welch Reviewed-by: Svyatoslav Ryhel

x86: coreboot: Look for DBG2 UART in SPL too

2023-09-21T22:03:46Z

If coreboot does not set up sysinfo for the UART, SPL currently hangs. Use the DBG2 technique there as well. This allows coreboot64 to boot from coreboot even if the console info is missing from sysinfo Signed-off-by: Simon Glass Reviewed-by: Bin Meng

Kconfigs: Correct default of "0" on hex type entries

2023-08-09T13:21:42Z

It is not a parse error to have a default value of "0" for a "hex" type entry, instead of "0x0". However, "0" and "0x0" are not treated the same even by the tools themselves. Correct this by changing the default value from "0" to "0x0" for all hex type questions that had the incorrect default. Fix one instance (in two configs) of a default of "0" being used on a hex question to be "0x0". Remove the cases where a defconfig had set a value of "0x0" to be used as the default had been "0".

x86: Allow locating the UART from ACPI tables

2023-05-11T02:25:29Z

When coreboot does not pass a UART in its sysinfo struct, there is no easy way to find it out. Since coreboot does not actually init the serial device when serial is disabled, it is not possible to make it add this information to the sysinfo table. Add a way to obtain this information from the DBG2 ACPI table, which is normally set up by coreboot. For now this only supports a memory-mapped 16550-style UART.
