linux-postmarketos-omap fails to mount vfat boot

Describe your issue

if /boot is fat32, initfs fails to mount it

What's the expected behaviour?

/boot gets mounted

What's the current behaviour?

mount fails because of iocharset=ascii is not there: CONFIG_NLS_ASCII is not set

FAT-fs (mmcblk0p1): IO charset ascii not found

btw: mounting without any options works (so without iocharset=ascii)!

have /boot as fat32 (deviceinfo_boot_filesystem="fat32") with linux-postmarketos-omap kernel
