[U-Boot] [PATCH] MIPS: bootm: Add fixup of '/memory' node.

[Daniel Schwierzeck]

2016-04-18 15:01 GMT+02:00 Purna Chandra Mandal <purna.mandal at microchip.com>:
> MIPS arch do not update 'reg' property of /memory node.
> As a result Linux bootup will not work unless board.dts
> file contains right /memory offset-size information or
> board implements required memory fixup.
> Fixing by renaming (unused) _arch_fixup_memory_node_ to
> _arch_fixup_fdt_ in arch/mips/lib/bootm.c inline with ARM arch.

thanks for catching. I've missed commit
e29607ed972056723e4bf0ac90767421cf0f0b78 at the time I merged this
patch set.
