[PATCH rza_u-boot-2017.05 0/2] rza2mevb: Allow using Ethernet when SDRAM is enabled

[Geert Uytterhoeven <geert+renesas@glider.be>]

	Hi Chris,

To use the 64 MiB of SDRAM on the RZA2MEVB development board, SW6-4 must
be switched off, making the first Ethernet port unavailable.
Fortunately RZA2MEVB has two Ethernet ports, so this patch series makes
U-Boot fall back to using the second port instead.

Note that this does not apply to upstream U-Boot, as the sh_eth driver
has been reworked in upstream, and as upstream does not support RZA2MEVB
yet.

While this allows me to use TFTP, I still cannot boot my own non-XIP
Linux kernel (uImage with LOADADDR=0x0c008000), as it seems to crash in
the "blcs cache_on" in linux/arch/arm/boot/compressed/head.S.  A similar
kernel boots fine on RSK+RZA1.

Thanks for your comments!
