[PATCH 00/10] Generic powerpc fixes and NXP board cleanup

While working on an ancient P2041 based board, I've encountered
several issues.

cpu_init_r wasn't called anymore, but u-boot was still somehow
working. CAAM was reading/writing on address 0 because pamu_init()
is never called if secure boot isn't enabled.

Since legacy ethernet was removed, board_eth_init() and
fdt_fixup_board_enet() won't be called anymore, but the functions
are still defined. I've just removed the ones for the NXP boards,
though I think the code there did something useful. But given that
it wasn't called for two years now and nobody complained, it can't
be that important.

Lastly, because I have a p2041rdb, move that to a upstream DTS.
Keep in mind, that the uboot dts doesn't define an UART, so any
output was broken since the move to DM provided serial support.

Michael Walle (10):
  powerpc: fix call to cpu_init_r
  caam: don't write memory at 0 on PPC
  spi: fsl_espi: fix read transactions
  boards: remove dead fman code
  boards/nxp: remove board_eth_init()
  boards/nxp: remove empty fdt_fixup_board_enet()
  p2041rdb: use the upstream device tree
  p2041rdb: support SDcard boot
  p2041rdb: update README and fix typos
  p2041rdb: remove NAND defconfig
