Subject: [PATCH v2 u-boot-mvebu 0/4] arm: mvebu: Fix eMMC boot
Date: Thu, 13 Apr 2023 22:57:46 +0200 [thread overview]
Message-ID: <20230413205750.10641-1-pali@kernel.org> (raw)
Boot configuration stored in EXT_CSD[179] register is completely ignored by BootROM:
https://lore.kernel.org/u-boot/CAOAjy5SYPPzWKok-BSGYwZwcKOQt_aZPgh6FTbrFd3F=8DM5ZQ@mail.gmail.com/
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:
