From: Simon Glass <simon.glass@canonical.com> Add folio_next_pos() and fgf_set_order() macros to ext4_uboot.h to match the Linux kernel API. folio_next_pos() returns the byte position following a folio, useful for checking if a folio extends past a given position. fgf_set_order() is a stub that returns 0 since U-Boot doesn't support large folios. In Linux, this is used to request a specific folio size when allocating.
