Could you do something similar for the fastboot case, so we can have a DTS
property (e.g. under /config or /chosen) to map back to the devnum on a
per-board basis?

I'm not sure if there two are similar the same case, for boot device, we
want to support more then one devices in an order, but for fastboot,
we usually do not support device other than eMMC.

Sorry for being a bit unspecific (but had hoped that the reference to the 
function
resolving a single of_node back to a devnum would have clarified what I intended
to say)…

I didn’t mean for you to use an ordered list, but rather a single referenced 
node.
E.g.
u-boot,fastboot-flash-device = <>;

I try to under stand what you want to do here, but again, I think this is 
different
with the boot order. The boot order have much choice, different sequence, so 
it's
reasonable for what you have done. But the FLASH_MMC_DEV is only one number,
not a list, not a node, just like CONFIG_SYS_MMC_ENV_DEV, it's quite easy to do 
it,
we do not need to write it in dts and decode the dts, what we need is give the 
correct
number to fastboot driver, and that's all.

While eMMC will be the default for most deployments, people may want to
use a different setting for their devices or during testing. In fact the way 
this
is used in the applications we see can be grouped along the following use
cases:
(a) production deployment
(1) sometimes fixed to the internal storage (i.e. eMMC)
(2) sometimes fixed to external storage (e.g. a eMMC on the baseboard)
(3) sometimes set to ‘same device the bootloader was loaded from'
(b) device development:
(4) often fixed to a specific storage device (can bei either ‘internal’ 
or
‘external’ storage)
(5) sometimes set to ‘same devices as the bootloader'

In other words, there’s a lot of variability in what is right for a specific 
application
and device, but this should not require a new board-configuration in U-Boot (or
a U-Boot rebuild).


Make the fastboot dev number select into dts instead of MACRO in header 
file can not
resolve the issue without bootloader update, but need to update fastboot 
cmd driver,

like the ums driver works good for the issue with the correct parameter:
'ums 0 mmc 0' vs 'fastboot usb0'

Thanks,

Philipp.
