One more thing ... eMMC hardware partition 0 and 7 are both referring to
USER HW partition. Have a look at the git log, there have been patches
which handled this case in the MMC subsystem from about a year ago.
Hi Marek,
I can't find what you are referring to. I assume you are talking about
calling the first name something other than 'user' as technically it's
not (but it gets treated as user).
Can you find the commit or discussion you are thinking about?
It seems this whole thing is much older:
7dbe63bc950b ("SPL: Add CONFIG_SUPPORT_EMMC_BOOT support to
CONFIG_SPL_FRAMEWORK")
+ * We need to check what the partition is configured to.
+ * 1 and 2 match up to boot0 / boot1 and 7 is user data
+ * which is the first physical partition (0).
+ */
+ int part = (mmc->part_config >> 3) & PART_ACCESS_MASK;
+
+ if (part == 7)
+ part = 0;
