Subject: [PATCH v2 u-boot-mvebu 4/4] arm: mvebu: clearfog: Update eMMC/SD/SATA instructions
Date: Thu, 13 Apr 2023 22:57:50 +0200	[thread overview]
Message-ID: <20230413205750.10641-5-pali@kernel.org> (raw)
In-Reply-To: <20230413205750.10641-1-pali@kernel.org>

BootROM and neither SPL does not use eMMC boot acknowledgement or boot
enable bits in EXT_CSD_PART_CONF eMMC register. And also fixed SATA disk
sector 0x141 is not used at all.
