[U-Boot] [PATCH] omap-common: SYS_BOOT fallback logic correction

[Paul Kocialkowski <contact@paulk.fr>]

By the way, would you like to add am33xx support to the SYS_BOOT-based
fallback interface?

There is already get_sysboot_value on am33xx code (that is unused), I
suggest that you use that function to write a proper
omap_sys_boot_device in boot.c, as is done on omap platforms (and get
rid of get_sysboot_value afterwards).

Most of the work is to fill up a boot_devices array to match up each
first *memory* booting devices based on the SYS_BOOT value, for each
supported platform. Currently, am33xx supports:
* AM33xx
* AM43xx
* TI81xx: TI816x (DM816x/AM389x), TI814x (DM814x/AM387x)

That's 4 platforms and 4 TRMs to get the data from. The list of proper
CONFIG defines to each for each platform can be found in
arch/arm/includes/asm/arch-am33xx/spl.h

Let me know if you're interested, I didn't do it at first because I have
no device to test this with.
