Daniel Schultz <d.schultz@phytec.de> says: This patch series extends PHYTEC's SOM detection by minor fixes, a generic helper function and a new valid flag. Moreover, it adds a module to provide access to the SOM detection for our TI AM6 products.
-
Add all functions to read each SOM option from the EEPROM image and detect whether it's the correct product for this image. Signed-off-by: Daniel Schultz <d.schultz@phytec.de>
-
The ptr variable is currently defined as int and sizeof returns the size of the eeprom data struct as Byte (32 in total). In case the eeprom is empty, the check, if the eeprom is empty, will most likely stop after 8 iterations because it will continue with the stack which should contain some data. Therefore, the init function will detect an empty EEPROM as API0 and return with the valid flag set to True.

-
For all of the functions that access the eeprom_data, make sure these data are valid. Use the valid member of the phytec_eeprom_data struct. This fixes a bug where only the API revision check guarded against accessing rubbish. But if API revision was e.g. 6, eeprom setup failed before, but phytec_get_imx8m_eth would still happily access the data.

Add a new nember to the eeprom_data that indicates whether the associated data is valid or not. Make use of this new member in the phytec_eeprom_data_init function by setting the valid value appropriately. Move the eeprom data to a new struct payload that holds the payload of the eeprom.

Judith Mendez <jm@ti.com> says: The following patch series includes a MMC tuning algorithm fix according to the following published paper [0]. This seris also includes fixes for OTAP/ITAP delay values in j721e_4bit_sdhci_set_ios_post and for HS400 mode. For DDR52 mode, also set ENDLL=1 and call am654_sdhci_setup_dll() instead of am654_sdhci_setup_delay_chain() according to device datasheet[1].

At HS400 mode the ITAPDLY value is that from High Speed mode which is incorrect and may cause boot failures. The ITAPDLY for HS400 speed mode should be the same as ITAPDLY as HS200 timing after tuning is executed. Add the functionality to save ITAPDLY from HS200 tuning and save as HS400 ITAPDLY.

Currently the sdhci_am654 driver only supports one tuning algorithm which should be used only when DLL is enabled. The ITAPDLY is selected from the largest passing window and the buffer is viewed as a circular buffer. The new tuning algorithm should be used when the delay chain is enabled; the ITAPDLY is selected from the largest passing window and the buffer is not viewed as a circular buffer. This implementation is based off of the following paper: [1]. Also add support for multiple failing windows.

Caleb Connolly <caleb.connolly@linaro.org> says: This is a subset of [1]. With more platform maintainers switching to OF_UPSTREAM I didn't want to get in the way (it has also proven more difficult than I hoped to remove only the fully compatible header files). This series removes only the dt-bindings headers which contain generic data like GPIO flags, input event codes, etc. It then implements support for building all DTBs for a vendor with OF_UPSTREAM_BUILD_VENDOR. This removes the need to maintain a set list of DTBs that can be built by U-Boot and opens up the possibility of new boards becoming supported "by default" just by landing their DT upstream.

This adjusts OF_UPSTREAM to behave more like the kernel by allowing for all the devicetree files for a given vendor to be compiled. This is useful for Qualcomm in particular as most boards are supported by a single U-Boot build just provided with a different DT.

MD Danish Anwar <danishanwar@ti.com> says: The series introduces device tree and config changes and AM65x to enable ICSSG driver. The series also enables SPL_LOAD_FIT_APPLY_OVERLAY for AM65x in order to load overlay over spl. The ICSSG2 node is added in device tree overlay so that it remains in sync with linux kernel. This series has been tested on AM65x SR2.0, and the ICSSG interface is able to ping / dhcp and boot kernel using tftp in uboot. The users need to set env variables fw_storage_interface, fw_dev_part, fw_ubi_mtdpart, fw_ubi_volume to indicate which storage medium and partition they want to use to load firmware files from. By default the env fw_storage_interface=mmc and fw_dev_part=1:2 but users can modify these envs as per their requirements.
-
When ICSSG driver is enabled (CONFIG_TI_ICSSG_PRUETH=y) set storage_interface and fw_dev_part env variables. These variables need be set appropriately in order to load differnet ICSSG firmwares needed for ICSSG driver. By default the storage interface is mmc and the partition is 1:2.

To workaround an issue in AM642 we reset the SoC in early boot. For that we first probed the sysreset driver by calling uclass_get_device(). The ti-sci sysreset driver is now probed during the ti-sci firmware probe. Update this call to probe the firmware driver which will then probe the sysreset driver allowing do_reset() to again function as expected.

In Linux, we allow sleep moci to be turned off when the carrier board supports it and the system is in suspend. In U-Boot, however, we want the sleep moci to be always on. So we use a gpio hog and disable the regulator. This change is necessary because we switched to upstream device tree files with commit c07bba7a ("verdin-am62: move verdin am62 to OF_UPSTREAM"). A recent upstream patch removes the gpio hog from the Linux device tree, so we need to add it to the u-boot dtsi. The following patch will remove the gpio hog from the Linux device tree: https://lore.kernel.org/linux-devicetree/20240301084901.16656-1-eichest@gmail.com/ The U-Boot patch can be applied without it and will not break the build.
