The k3-am62a7-sk.dts describes an I2C PMIC TPS659312 which features a
number of regulators. One of them, ldo1, is used as power supply for the
SD card host controller regulator. When the rootfs is on the SD
card (like with this configuration), we need support for these three
components (Regulator driver, I2C PMIC glue and PMIC MFD driver) to be
built-in in order to avoid boot failures.
Tested on an AM62A LP SK.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC.
