This patchset is used to fix a host version register bug in the T4240-R1.0-R2.0
eSDHC controller. To match the SoC version and revision, 10 previous version

Update Freescale DCFG compatible with 'fsl,-dcfg' instead
of 'fsl,ls1021a-dcfg' to include more chips such as ls1021a,

Hi Paul!
I'm referring to your change [1]:
"powerpc/xmon: Fix SPR read/write commands and add command to dump SPRs"
which introduced assembly code in the new file arch/powerpc/xmon/spr_access.S.
Unfortunately, this code contains assembly instructions which are not available
on
all ppc targets.
