[U-Boot] [PATCH 00/10] rockchip: Tidy up SPL operation on jerry

[U-Boot] [PATCH 00/10] rockchip: Tidy up SPL operation on jerry

[Simon Glass]

At present chromebook_jerry does not boot due to a configuration error and
a missing Makefile piece. This series fixes that and also adds a few more
adjustments mostly related to SPL and pinctrl.

The first three patches could perhaps be applied for this release - the
rest are for later.

for building a SPI image are no-longer correct. Fix these so that Jerry can
boot to a prompt again.

[U-Boot] [PATCH 07/10] dm: mmc: Try to honour the sequence order

[Simon Glass]

At present we add driver-model MMC devices in the order we find them. The
'alias' order is not honoured.

It is difficult to fix this for the case where we have holes in the
sequence. But for the common case where the devices are numbered from 0
without any gaps, we can add the devices to the internal data structures
in this order.
