[PATCH 0/2 V2] RGXX3: Set boot order for mmc0 first

[PATCH 0/2 V2] RGXX3: Set boot order for mmc0 first

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Set the rgxx3 device to boot from mmc0 first. This serves as a fallback
to allow us to recover from a bad U-Boot (or later) stage in a worst
case scenario. The code for an ADC button appears to have broke some
board revisions; this solution is much simpler and allows users to
continue to program the adc button as they see fit.

Changes from V1:
 - Removed sdmmc1, as long as we have sdmmc0 we should be safe.
 - Clarified that the expectation is that we can prevent a bad
   U-Boot stage with a valid FIT signature by looking at removable
   storage first.

[PATCH 1/2 V2] Revert "board: rockchip: Add early ADC button detect for RGxx3"

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

This reverts commit 41a60d0e5cef54a59596a58940fa7c9cf071034b.

On some of the supported devices the adc detect code always returns
that the button has been pushed, and as a result the device will
not boot normally.

Have you check the key input voltage with voltameter which can identify 
is hardware issue or software issue.

It's a software issue. I confirmed I actually could have fixed it by
using the ADC driver (which sets up the interrupt registers correctly).
However, there is something to be said of keeping things simple. I
should have taken your advice from the get-go and just done that.

Thank you.

[PATCH 2/2 V2] board: rockchip: rgxx3: Use sdmmc0 as first device

[Chris Morgan]

From: Chris Morgan <macromorgan@hotmail.com>

Some of the rgxx3 devices do not have a way to recover from a poor
flash of a bootloader to eMMC. Set the device to always attempt to boot
from sdmmc0 first which ensures that we can override the boot from
emmc if we have a card present with a valid fit signature. The
expectation is that this will protect from the very unlikely chance
we have a valid FIT signature on the eMMC but the U-Boot stage fails
for some other reason.
