Re: [U-Boot] [PATCH 3/4] [v3] nand_util: drop trailing all-0xff pages if requested

Hi Ben,

Add a flag to nand_read_skip_bad() such that if true, any trailing pages in an eraseblock whose contents are entirely 0xff will be dropped.

The implementation is via a new drop_ffs() function which is based on the function of the same name from the ubiformat utility by Artem Bityutskiy.

This is as-per the reccomendations of the UBI FAQ [1]
