When constraining the highest DDR address that U-Boot will use for its data & relocated self, we need to handle the common case in which a 32 bit system with 2GB DDR will have a zero gd->ram_top, due to the addition of 2GB (0x80000000) to the base address of kseg0 (also 0x80000000) which overflows & wraps to 0.
We originally had a check for this case, but it was lost in commit 78edb25729ce ("boston: Provide physical CONFIG_SYS_SDRAM_BASE") causing problems for the affected 32 bit systems.
I think I did a wrong conflict resolution because the patch didn't apply anymore. I folded this patch into "boston: Provide physical CONFIG_SYS_SDRAM_BASE" to fix this. Actually I wanted to resend the updated patches. But if you are okay with the current state in u-boot-mips/next branch, I'll take them as they are.
BTW: could you resend your series "boston: Ethernet support for MIPS Boston board"? I still have no Acks or Reviews on the generic DM parts. Thanks.
