Unfortunately, it does not seem to work in my tests: ldp-board-no-battery uses upstream u-boot in a chainloaded configuration + does not have battery plugged in, instead, just J58 (charger) is connected - this is plugged on a remote farm setup for developers to work with. ldp-board-with-battery uses legacy bootloader with a battery simulator. omap2plus_defconfig + CONFIG_CHARGER_TWL4030 enabled.
