board: phytec: phycore-imx91-93: Add phyCORE-i.MX91 support

2026-04-02T12:05:23+00:00

As the PHYTEC phyCORE-i.MX91 [1] is just another variant of the existing
PHYTEC phyCORE-i.MX93 SoM but with i.MX91 SoC populated instead, add it
to the existing board-code "phycore_imx93", and rename that board to
"phycore_imx91_93" to reflect the dual SoCs support. While at it, also
rename and change common files accordingly. This way i.MX91 and i.MX93
SoC variants of the phyCORE SoM share most of the code and documentation
without duplication, while maintaining own device-tree and defconfigs
for each CPU variant.

Supported features:
 - 1GB LPDDR4 RAM
 - Debug UART
 - EEPROM
 - eMMC
 - Ethernet
 - SD-card
 - USB

board: phytec: phycore-imx93: Enter fastboot on USB boot by default

2026-02-28T18:31:49+00:00

In case board is booted from USB, enter fastboot by default to enable
the UUU flashing. In case of abort continue with the regular bootstd
scan. User also has possibility to override the default bootcmd from
the environment. Last but not least, this syncs behavior with other
PHYTEC boards from the i.MX family.

board: Correct usage of fdtfile=CONFIG_DEFAULT_FDT_FILE

2026-02-23T21:30:34+00:00

As explained in commit 03d2d5fc003f ("board: sifive: unmatched: set
fdtfile with unquoted variable.") using the syntax of
'fdtfile=CONFIG_DEFAULT_FDT_FILE' in the plain text environment files
will lead to extraneous and problematic "s in the output. This is fixed
by using fdtfile=DEFAULT_FDT_FILE which was introduced recently.

treewide: Clean up DECLARE_GLOBAL_DATA_PTR usage

2026-02-17T19:50:22+00:00

Remove DECLARE_GLOBAL_DATA_PTR from files where gd is not used, and
drop the unnecessary inclusion of asm/global_data.h.

Headers should be included directly by the files that need them,
rather than indirectly via global_data.h.

board: phytec: Add PHYTEC mailing list to MAINTAINERS entries

PHYTEC maintains an actively monitored mailing list for upstream
activities: upstream@lists.phytec.de. Add it to the MAINTAINERS
entries for PHYTEC boards we actively develop and contribute to.

board: phytec: phycore-imx93: Set boot_targets dynamically

2025-12-06T18:26:07+00:00

Set boot_targets environment variable dynamically, so that when booting
from SD-card, boot binaries are also preferably fetched from the SD-card
by default. If the user decides to set their own boot_targets, we should
not overwrite them.

board: phytec: phycore-imx93: Switch to standard boot

2025-12-06T18:26:07+00:00

Enable standard boot for the phyCORE-i.MX93 board and use it as a new
default. Add required standard boot variables to the environment, while
removing old boot scripts and now unnecessary environment variables.
Adjust variables according to the requirements of PHYTEC ampliphy-boot
distro-boot. Last but not least, order environment vars by alphabet and
run 'make savedefconfig' to resync defconfig.

board: phytec: phycore-imx93: Fix i.MX93 voltage modes

2025-09-21T12:09:13+00:00

Fix support for i.MX93 voltage modes on phyCORE-i.MX93 SoM boards.

First of all, Kconfig option CONFIG_IMX9_LOW_DRIVE_MODE is gone since
commit c9efcad23741 ("imx93_evk: Remove CONFIG_IMX9_LOW_DRIVE_MODE and
ld defconfig") and was replaced by runtime detection mechanism. Thus
lets use is_voltage_mode() instead of Kconfig to detect CPU type and
select proper voltage mode.

Secondly, 1400MHz ND mode (Nominal Drive) requiring 0.85V BUCK voltage
was not supported with current power_init_board() PMIC settings. Add
check also for this CPU type and set BUCK voltage accordingly.

Last but not least, add printf() printouts about PMIC voltage mode to
the console. This makes it more apparent and verbose about voltage mode
in use. Also our internal tests depend on this printout to catch issues
with i.MX93 CPU types and set PMIC voltage modes.
