[PATCH v2 0/1] Add Kindle generation 6/7 support

[Alexander Kurz]

Changes in v2:
- Link to v1: https://lore.barebox.org/barebox/aRMOO3jH4a16GBI6@pengutronix.de/
- Remove explicit RAM size settings from lowlevel.c and dts since this can be
  autodetected. As consequence, both DP75SDI variants (Paperwhite 2 and 3) now
  share the same dts.
- Rebase to current
- Attempts to use barebox,deep-probe did unfortunately not work yet.
  Brief description of the problem:
  Device specific data is stored in /dev/mmc1.boot0.userdata, this data
  is read by barebox and passed as ATAGs to the vendor kernel, without this
  data, the device won't work properly.
  An attempt has been made to use barebox,deep-probe (see patch below), however,
  mmc1 will not be available later, resulting e.g. in an error
  > Could not read board info from /dev/mmc1.boot0.userdata
  during startup.
