Boot configuration stored in EXT_CSD[179] register is completely ignored by BootROM:

Instead eMMC partition use for booting has to be extracted from Partition access bits:
https://lore.kernel.org/u-boot/CAOAjy5SNrLJ=JAKf96Nf7HkFBXWbZLmWAhEs6nEEHS6UEhQbJw@mail.gmail.com/

Reflect this eMMC booting in documentation and in the code.

This patch series does not address 5 minutes timeout as nobody reacted to the email:
