Worked on the phytec/doc-bsp-yocto repository to enhance documentation accuracy regarding TPM hardware support for phyBOARD-Segin and Nash i.MX 91/93 boards. Focused on technical writing and documentation using reStructuredText, the update removed an incorrect claim about TPM availability and clarified that these boards do not include a TPM. The documentation now explicitly advises users to verify hardware specifications, reducing the risk of misconfiguration and aligning the Yocto BSP documentation with actual hardware capabilities. This approach improved user guidance and is expected to decrease support requests by ensuring that customers and field teams have accurate, up-to-date technical information.
